Changelog

A running log of what's changing inside lacuna.fm— new tools, improvements, and small details we couldn't resist polishing.

New free tools, rhyme in eight languages, and stems on the canvas

This release adds two free tools — an AI Song Name Generator and an MP3 Tag Editor — plus a dedicated AI Rap Generator, brings live rhyme highlighting to the Lyrics Writer in eight languages including Chinese, Japanese, and Korean, and lets you split songs into stems and trace your work right inside the studio.

  • Two new free tools, no account needed — an AI Song Name Generator and an MP3 Tag Editor
  • A dedicated AI Rap Generator for hip-hop styles like boom bap, trap, and drill
  • Rhyme highlighting in the Lyrics Writer now works in eight languages, including Chinese, Japanese, and Korean
  • Split any of your songs into separate stems right on the music canvas
  • A smarter studio chat that hands you tool shortcuts and shows how each song was built

This release leans into control and craft — a page built just for rap, two free tools you can use without an account, rhyme you can actually see while you write, and more you can do without leaving your project.

A generator built for rap

There's a new page dedicated to rap. Type an idea and get back a finished track — original bars, rap vocals with real flow, and a beat — in about a minute. Pick a direction like boom bap, trap, drill, West Coast, melodic, or old school, set the mood and tempo, choose your instruments, and either write your own bars or let the AI write them for you. Want just the beat? Make it instrumental. Everything you create is saved to a tracks panel where you can play, download, share, star, or open it in the full studio to keep editing.

Two free tools: name your song, tag your MP3

Two small tools, free and open to everyone — no account required.

The AI Song Name Generator turns a one-line description into a batch of title ideas, each with a note on the vibe it captures. Pick a genre and mood, ask for shorter, longer, or more poetic variations, pin your favorites, and jump straight into making the song once you've landed on the name.

The MP3 Tag Editor lets you fix up an MP3's details — title, artist, album, genre, year, and more — and swap or crop its cover art, then download the updated file. It all happens in your browser, so the file never leaves your computer.

Name a song → · Edit MP3 tags →

See your rhymes, in any language

The Lyrics Writer now shows your rhyme scheme as you type. It draws colored lines between the lines that rhyme, giving each rhyme group its own color so you can read your pattern at a glance, and it counts syllables per line to help you hold your meter. It detects the language you're writing in automatically — or you can lock it yourself — and it now understands eight languages, including Chinese, Japanese, and Korean, where before it only worked in English.

Open the Lyrics Writer →

Split any song into stems, on the canvas

Inside the studio you can now break a song into its parts without leaving your project. Choose how finely to split it — vocals and instrumental, a four-part split into vocals, drums, bass, and the rest, or a six-part split that also pulls out guitar and piano. A new card appears next to your song, and once it's ready you can play each part on its own.

Open the studio →

A studio chat that keeps up

The assistant in the studio got three upgrades. When you ask for something it can't do itself — like making a MIDI file or splitting audio into stems — it now hands you a card that takes you straight to the right tool. After it edits one of your tracks, it leaves a shortcut chip in the chat that reopens that exact edit later. And it now draws soft colored threads linking each finished track back to the recipe it came from, so you can trace how a song was built even in a long conversation.

Smaller things

  • Images across the site load faster, scaled to your screen and served in modern formats.
  • A round of visual refinements to the full-screen player and the music workspace.

Custom mode, a country song generator, and a new voice

The music studio now has a hands-on Custom mode where you set the style, lyrics, title, and vocals yourself instead of chatting. There's also a dedicated AI Country Song Generator, now live in all nine languages, and a new song model, Reverie, that sings your exact lyrics and returns two versions per run.

  • New Custom mode — set style, lyrics, title, and vocals directly instead of chatting with the AI
  • A dedicated AI Country Song Generator, now in all nine languages
  • Reverie, a new song model that sings your exact lyrics and returns two versions per run
  • Reuse lyrics you've saved from Lyrics Studio, right in the song form
  • The premium Nocturne model is cheaper now — 180 credits instead of 200

This release is about giving you more direct control over how a song gets made — a new hands-on way to create, a page built just for country, and a new voice to make it with.

Take full control with Custom mode

The studio now lets you choose how you work. Agent keeps the conversational flow where the assistant guides you step by step. The new Custom mode gives you a direct form instead: set the musical style, write or paste your own lyrics, name the track, choose vocals or instrumental, pick a model, and generate in one click. Your choice is remembered between visits, and inside a Custom project the form stays open in the workspace so you can adjust any field and regenerate — each new version lands right on the canvas.

Start creating →

A song generator built for country

There's a new page dedicated to country music. Describe a story, a place, or a feeling, pick a direction — heartbreak ballad, outlaw road anthem, small-town nostalgia, honky-tonk, or bluegrass — set the mood, tempo, and instruments like pedal steel, fiddle, and banjo, then generate a full song with lead vocals and a real band. Write your own lyrics with AI help, or keep it instrumental. Everything you make is saved to a My songs tab where you can play, download, share, or delete it. The page is live in all nine site languages.

Make a country song →

Meet Reverie

A new song model, Reverie, joins the model picker. It renders the exact lyrics you write in natural, expressive vocals, and returns two versions in a single generation so you have a choice to start from. The premium Nocturne model is also cheaper now, dropping from 200 to 180 credits.

Pick a model →

Smaller things

  • Reuse lyrics you've saved — pick from your Lyrics Studio library right inside the song form, in both the music workspace and the country song generator.
  • The model picker now shows how many songs each model produces and whether cover art is included.

A new look, a better phone experience, and a smarter music chat

The whole site got a visual refresh built around a new homepage that plays music, the player and navigation have been rebuilt for phones, the assistant in the music workspace gives better answers, pricing now spells out what your credits get you, and your tracks can ship with a downloadable commercial license.

  • Redesigned homepage with playable showcase songs, curated for your language
  • A refreshed look across the whole site — type, color, and detail
  • Player and navigation rebuilt for phones
  • The music chat assistant gives clearer, more useful answers
  • Pricing breakdown of what credits get you, plus commercial license downloads

This release is a broad refresh of how the product looks and feels — starting from the homepage, going deep on phones, and reaching into the chat where you make music.

A homepage that plays

The homepage has been rebuilt around actual music. The new hero puts an album wall and a player front and center, showcase songs are curated per language so you hear examples that fit how you'd actually use them, and a stems view lets you take featured songs apart layer by layer. New sections walk through what the studio does and who it's for.

A refreshed look, everywhere

The visual language has been upgraded across the site — type, color, spacing, and the small details in buttons, dialogs, and badges. Pages feel calmer and more consistent, and the same design carries through from the homepage to the workspace.

Built for your phone

The mobile experience got the most attention it's ever had. The player is now a compact dock that stays out of the way while you browse, navigation and the top header have been reworked for small screens, and the full-screen player is one tap away from anywhere.

Clearer answers in the music chat

The assistant you talk to while making music now answers more to the point — it's better at understanding what you're going for, and clearer about what it did and what to try next.

Pricing, spelled out

Plan cards have been reworked, and there's a new capability table that shows exactly what your credits translate to across every feature — songs, lyrics, MIDI, and more — so you can compare plans on what they produce, not just their numbers.

See plans →

Commercial licenses for your tracks

When you download a track you made, you can now download a commercial license document along with it — your name, the track, and the rights, in one PDF you can keep on file or hand to a client.

Smaller things

  • Signing in is faster: Google users get a one-tap prompt instead of a full redirect.
  • Tool hubs now share a tab bar, so switching between generators takes one tap.
  • Public pages load noticeably faster.

Your generated songs now live inside the music chat

The results you generate, the directions the AI suggests, and a heads-up when songs finish rendering now all appear right inside the workspace chat — play a track, preview it while it's still rendering, or start a new version, without switching over to the canvas.

  • Generated songs appear as playable cards in the chat, in the order you made them
  • Preview a song while it's still rendering, then play the finished version in place
  • AI-suggested directions show up as cards you can generate from with one tap
  • A reminder gathers up any results that finished while you were looking away

Until now the workspace chat was where you talked to the AI, and the canvas was where the music showed up — so after asking for a song you had to look somewhere else to hear it. This release brings the results back into the conversation.

Hear your results where you asked for them

Every song you generate now appears as a card in the chat itself, placed in the order you created it rather than pushed to the bottom. While a song is still rendering, you can play an early preview of each take straight from its card; the moment it finishes, the card turns into the final, playable version in place — no jumping around, no hunting on the canvas. If a generation fails, the card says so right where you expected the song.

Start a new song →

Generate from a direction, right in the chat

When the AI lays out creative directions for you, each one now shows up in the chat as its own card — with its style, tempo, and vocal at a glance. Tap to generate a song from it on the spot, or open the matching card on the canvas to fine-tune it first. Directions carry the same number and color in the chat as they do on the canvas, so the two always line up.

A heads-up when results are ready

Kick off a few songs, scroll up to keep working, and the ones that finish out of view collect into a single reminder at the top of the chat: how many are ready, with a tap to preview each or jump to it. It clears itself as you catch up.

Smaller things

  • Songs drafted in ChatGPT and sessions opened from someone else's link now display in your own language instead of defaulting to one.
  • The scroll-to-bottom button in chat is easier to see against busy conversations.

A data study on who is really making AI music

A first data study of ~650,000 AI music generations, plus a blog you can read and hear in one place.

  • A study of ~650,000 AI music generations, in nine languages
  • Charts, callouts, and audio you can play inside the article
  • Polished navigation, footer, and mobile menu

Who is really making AI music

We read about 650,000 AI music generations from across the space to answer the question the "AI slop" headlines skip: who actually writes the music? On the creation side, people bring their own lyrics, mark up the structure section by section, cast a specific voice, and come back to do it again — one-click-and-leave is a small slice. It's our first full data study, in nine languages. Read it →

Smaller things

  • The blog now has charts, callouts, and audio you can play right in the article.
  • Polished the navigation bar, footer, and mobile menu.
  • Tightened spacing and timeline details in the music chat.

Edit your music — remix, extend, and rewrite any section

The biggest update to the music workspace yet — remix a track into a new style, continue it past the ending, or rewrite just one section by selecting it on the waveform, with an AI lyrics assistant working alongside you.

  • Remix a finished track into a new style with AI-suggested directions
  • Extend a song past its ending, with the continuation visualized on the waveform
  • Rewrite the lyrics of one section by selecting it directly on the waveform
  • An AI lyrics assistant that edits your draft live while you chat
  • Redesigned cover art regeneration and a more capable assets library

Until now, a generated track was final — if the second verse bothered you, your only option was to regenerate the whole song. This release changes that.

Remix, extend, or rewrite a section

Every finished track in your workspace now carries three editing actions, each opening a new editing dock at the bottom of the canvas with the track's waveform front and center.

  • Remix reinterprets the whole track in a new style while keeping its character. Instead of typing a style prompt, you pick from chips — we split out the original track's style tags and suggest three remix directions tailored to the song.
  • Extend continues the song past its ending. Drag the start point on the waveform, and a ghost segment shows where the new section will go.
  • Edit a section rewrites the lyrics of just one part. Drag to select the section on the waveform — everything outside stays untouched.

Edited results appear on the canvas as new tracks, linked back to their source with a colored ribbon so you can always trace where a version came from.

Open your workspace →

Lyrics that know where they are

When you select a section on the waveform, the lyrics editor shows the full original lyrics with your selection highlighted and editable — the surrounding lines stay dimmed for context, so you always see exactly which words will change. Move the selection and the editable part follows.

Behind this, every vocal track now gets time-aligned lyrics — so synced lyric scrolling in the fullscreen player works on all models, not just some.

An AI lyrics assistant, while you edit

While an editing dock is open, the workspace chat becomes a lyrics assistant for that edit. Ask it to rewrite a verse, polish the wording, or continue the lyrics — its edits stream straight into your draft, line by line. Three one-tap shortcuts (inspire, polish, continue) work on whatever you've selected.

Redo your cover art without leaving the workspace

A new cover dock lets you regenerate a track's album art in place — write a prompt or let AI suggest one based on the track's title and style, browse style ideas, generate up to four candidates, and apply the one you like. The new cover updates everywhere at once.

Your library, reorganized

The assets library now covers everything you've made across six tabs — songs, stems, lyrics, MIDI, sheet music, and covers — with search, starred filtering, and pagination. Songs can be grouped by project, and edited tracks carry a small chip showing how they were made.

Smaller things

  • Every player control now has a proper tooltip, and volume moved into a compact popover with precise control.
  • Like and dislike buttons stay visible in the player bar instead of disappearing after rating.
  • The fullscreen player now slides up smoothly from the bottom bar.
  • Clicking a waveform while paused cues the position instead of unexpectedly starting playback.
  • Tracks generating on the canvas now appear where they'll end up, so nothing jumps around when they finish.

A more polished fullscreen player

We refined the fullscreen player — synced lyrics that scroll with soft fading edges, and an audio visualizer that stays graceful even when a track can't be analyzed.

  • Synced lyrics now scroll with softly faded top and bottom edges
  • The audio visualizer falls back gracefully instead of hanging on "Analyzing"
  • Small refinements across the player and music workspace

We spent this release sweating the details of the fullscreen player.

Lyrics that read better

When you open a track fullscreen, the lyrics follow along line by line, and now the top and bottom of the view fade out softly so your eye stays on the line that's playing.

Open the player →

A steadier audio visualizer

The visualizer behind a playing track is more resilient — if a track's audio can't be analyzed, it settles into a calm decorative pattern instead of getting stuck on a loading message.

Smaller things

  • Refinements to the music workspace — the track panel, sidebar, and model picker.
  • Each model now has its own accent color so you can tell them apart at a glance.

A clearer credit history, and examples you can tidy away

Your credit history now uses color to tell top-ups, everyday usage, and the rare error apart — and the example showcases on each creation tool can be dismissed once you've found your footing.

  • Credit history is color-coded by what each entry means, so top-ups and errors stand out
  • Everyday feature usage no longer shows up in alarming red
  • The example showcases on each tool page can now be dismissed and stay hidden

A credit history you can read at a glance

Your credit history used to paint nearly every entry red, which made an ordinary track generation look the same as an error. Now entries are colored by what they actually mean: top-ups and purchases stand out, everyday usage stays neutral, and only genuine failures show up in red. The amounts are quieter too — additions in green, everything else in plain text.

See your history →

Tidy away the examples once you know your way around

Every creation tool opens with a row of example showcases to give you a starting point. Once you've got the hang of it, you can dismiss them — click the close button in the corner, confirm once, and that page stays clean from then on. Each tool remembers its own choice.

Smaller things

  • Better screen-reader labels across the chat input and its buttons.

A reimagined music workspace — multi-DNA creation, a new canvas, and streaming AI

Explore several musical directions in one project, arrange your tracks on a canvas that remembers your layout, and watch the assistant respond in real time — plus a smoother lyrics editor, paginated history, and redesigned plans.

  • Multi-DNA creation — chase several directions in a single project
  • A canvas that remembers your layout, with richer track details
  • Streaming AI responses as they are written
  • A smoother lyrics editor with live syllable counts
  • Paginated history for tracks and lyrics, plus a redesigned pricing page

This release rebuilds how you make music in Lacuna — from a single back-and-forth into a workspace where you can explore several directions at once and shape each one on its own.

Explore several directions at once

Every project now supports multiple musical DNAs, so you can chase more than one idea without starting over. Pick references with the new context picker and let each direction evolve independently.

Open the workspace →

A canvas that remembers your layout

Your tracks live on a canvas you can arrange however you like, and your layout is saved between visits. Open any track for a richer detail panel that keeps everything in one place.

Real-time responses

The assistant now streams its replies as they are written, so you watch ideas take shape instead of waiting for the whole answer to land.

A smoother lyrics editor

Writing and refining lyrics is calmer now — your edits stay in sync as the assistant suggests changes, and syllable counts update as you type.

Write lyrics →

Browse your full history

Music and lyrics history is now paginated, so you can scroll back through everything you have made without the page slowing down.

Clearer plans, bigger batches

We redesigned the pricing page to make plans easier to compare, and you can now generate up to 16 songs in a single run — with larger batches on Pro and Ultra.

See plans →

Smaller things

  • A new top navigation that is cleaner and easier to move around.
  • Inline help hints next to less obvious labels, so you are never guessing what something does.
  • Refreshed buttons, backgrounds, and polish across the landing pages.

Watch each track take shape as it generates

Open a track while it's generating and follow along live — a placeholder while it composes, a playable streaming preview the moment one is ready, then the finished track in place. Plus a badge on every track showing which model made it.

  • A live detail view while a track generates, with a playable streaming preview
  • The canvas focuses the track being generated, then frames the result
  • Every track shows which model created it — Aether, Echo, or Nocturne

A follow-up to the new workspace: now you can watch a track come together while it generates, instead of waiting for it to land.

Follow a track as it generates

Open a track while it's still generating and the detail panel keeps up in real time. It starts with a placeholder while your track is composed, switches to a playable streaming preview the moment one is ready, and seamlessly turns into the full track once it finishes — no clicking around to find the result.

Open the workspace →

The canvas stays with you

When you start a track, the canvas focuses on it so you can see progress where it's happening, then reframes to fit the finished result.

Know which model made each track

Every track now carries a small badge for the model behind it — Aether, Echo, or Nocturne — so you can tell at a glance how each one was made.

Smaller things

  • Track styles now read as individual tags instead of one long line.
  • When the assistant lays out your first DNA, it opens automatically so you can dive straight in.

Smoother music workspace — live updates, multi-take previews, accurate history

A round of fixes to the music generation workspace — generation progress reaches the UI as soon as it happens, every take from a multi-take generation is playable while the rest finishes, and version history now highlights the snapshot you actually restored.

  • Generation status updates arrive reliably the moment a track finishes
  • All streaming previews from a multi-take generation are playable, not just the first one
  • Version history highlights the snapshot you actually restored
  • Restoring a lyrics version no longer leaves a duplicate entry in history
  • Several dialogs no longer overflow on mobile screens
  • Three Lacuna GPTs are now linked from the footer — Lyrics Generator, Music Generator, and Song Creator

Generation updates feel live again

Progress and "ready to play" state now reach the workspace immediately when a generation finishes, even after the server restarts. If you noticed the canvas occasionally getting stuck on "rendering" when the audio was already ready, that is fixed.

Hear every take while the rest is still rendering

When a generation produces multiple takes, all of them now appear as live preview buttons on the loading card the moment they are ready — not just the first one. Pick whichever take you like and start listening while the others continue rendering.

Version history points at the right snapshot

Music DNA and lyrics history now highlight the snapshot you actually restored, and update correctly after you create a new one. Restoring a lyrics version also no longer creates a duplicate entry in history.

Three Lacuna GPTs on ChatGPT

Prefer to work inside ChatGPT? Three custom Lacuna GPTs are now linked from the site footer:

Smaller things

  • Share, pricing, recipe, and a couple of showcase dialogs no longer overflow off-screen on phones.
  • Chat replies in the music workspace no longer occasionally show raw JSON for suggestion chips or DNA fields inline.

Stem separation, with a live mixer

A new tool that splits any song into its parts — vocals, drums, bass, and more — plus a real-time mixer to play with the result. The global audio player has been reworked, and ChatGPT GPT sessions can now be forked into Lacuna.

  • Split any song into vocals, drums, bass, and other stems
  • A live mixer to mute, solo, and rebalance the parts as they play
  • A library of showcase songs to try before you upload
  • Global audio player reworked, with a new full-screen view and smoother cross-page playback
  • Fork ChatGPT GPT sessions for music and lyrics into a Lacuna workspace

Stem separation

A new tool that splits any track into its core parts — vocals, drums, bass, and other instruments. Upload a song, or pick one from your library, and Lacuna gives each stem back as its own audio file.

Try it →

A live mixer

Splitting is just the start. The stems page comes with a built-in mixer — mute, solo, or rebalance each part while the song plays. The fastest way to hear what a track sounds like without vocals, with drums solo'd, or with everything but the bass dropped out.

We've also seeded a showcase library across genres so you can try the whole flow without uploading anything of your own first.

A reworked global audio player

The player at the bottom of the app has been rebuilt:

  • Persistent across pages — keep listening while you browse to a different hub
  • A new full-screen view with bigger artwork and cleaner controls
  • Track-type badges so you can tell at a glance whether you're playing a generation, a stem, or an upload

Fork from ChatGPT

If you use the Lacuna GPT inside ChatGPT to draft lyrics or songs, you can now fork that session straight into a Lacuna workspace — lyrics, prompt, and context preserved — and continue refining from there.

Smaller things

  • All hub cards now show relative times ("3 minutes ago") instead of static timestamps
  • Polished the showcases, segmented controls, and scroll fades across the app
  • Tightened the music workspace layout and global player bar

MIDI to sheet music, plus a faster assets library

A new MIDI to sheet music converter, full-screen previews for sheets and covers in the assets library, and the ability to star your favorite generations.

  • Turn any MIDI file into clean printable sheet music
  • Preview sheets and album covers in full screen without leaving the library
  • Star your favorite generated covers for quick access

MIDI to sheet music

Upload a MIDI file and get a clean, printable score back — not just notes on a grid, but real engraved sheet music. Keep a history of conversions, preview the output inline, and export as PDF or image when you're ready.

Try it →

A better assets library

Your assets library now has full-screen preview dialogs for sheet music and album covers, so you can inspect anything without downloading first. Cover generations can be starred for quick recall later, and the grid has been tightened up for easier browsing.

Open library →

Smaller things

  • Polished the top navigation, mobile menu, and music sidebar
  • Refined the album cover generator hub

Album covers, lyric inspiration, and a redesigned hero

A new album cover generator, an AI lyric muse to break writer's block, a redesigned music creation hero with vocal modes and inline lyrics, plus live task status in your browser tab.

  • Generate album covers from a prompt, lyrics, or your mood
  • Lyric muse — turn fragments into verses without leaving the page
  • Redesigned music hero with vocals/instrumental toggle and model picker
  • Live task status now shows on your browser tab favicon
  • A friendlier 404 with a hidden surprise

Album cover generator

A new tool dedicated to artwork. Describe the vibe, drop in lyrics, or pick a style — Lacuna composes a cover that matches the song you're writing. Try it →

Lyric muse

Stuck on a verse? The new lyric muse turns half-formed lines into something you can sing. It lives right inside the music creation flow — no extra page, no friction.

A redesigned music hero

The home and music pages now share a single, focused entry point:

  • Inline lyrics expansion — paste or write lyrics without leaving the box
  • Vocals vs. Instrumental — explicit toggle, no guessing
  • Model picker — pick your preferred model up front
  • Attachment menu — image, audio, and reference files in one place

Task status on your tab

Running a long generation in the background? Your browser tab favicon now turns blue while a task is running, green when it succeeds, red on failure. Switch tabs freely — Lacuna will quietly tell you when something's ready.

Smaller things

  • A new Tools page collecting everything Lacuna can do
  • Mobile menu redesigned with smoother transitions
  • A redesigned 404 page — try playing with it
  • Contextual nudges to help you discover features as you explore
