AI Music Generator — Turn a Spark into Sound
AI music agents for songs, lyrics, MIDI and live coding
Describe what you want in plain words. Each agent works on the real thing (the song, the lyrics, the notes or the code), and you can still edit the lyrics, notes and code yourself.
AI Music Agent
Describe a song and the agent drafts two directions and starts on the first. Then remix, extend, edit or master any track on a visual canvas.
AI Lyrics Agent
Chat with an AI songwriter that writes and rewrites your lyrics in an editor beside the chat, a line or a section at a time, then take them to the Music Agent to make a song.
AI MIDI Agent
Ask for a melody or an edit in plain words. The agent writes the notes into the piano roll, and each request can be undone in one click.
Strudel AI Agent
A Chrome side panel for live-coding music on Strudel. It reads your pattern, explains it and rewrites it when you describe the sound you want.

One Lacuna account and one credit balance work across every agent.
Your AI Music Team, on One Canvas
Connect every step — writing, arranging, generating, and stem-splitting — on one visual canvas
- One idea
- Two directions
- Four tracks
- Every edit, its own branch
Edit, Remix and Extend Every Track — Without Starting Over
Remix, extend, rewrite a section, split stems, or master — directly from the track node
Change the lyrics of one section with AI
Region Edit is an AI music editor for one section of a song. Select the section on the waveform and write the new lyrics; Lacuna regenerates only that part, and the rest of the song stays as it was. Use it as a song lyrics changer for a few lines, a chorus or a verse, without generating the song again.
- The original lines are pre-filled when lyrics are synced
- A built-in lyrics assistant helps draft the new lines
- Saved as a new version; the original stays on the canvas
Remix a whole song in a new style with AI
Remix is an AI song remixer that reimagines the whole track. Describe the sound you want, or start from style directions suggested for the song, then keep the lyrics or rewrite them. Your original audio serves as the reference, so the AI remix starts from your song, not from scratch.
- The style prompt starts from the song's own style
- Up to three versions per run on higher plans
- Each remix is saved next to the original
Create album art without leaving the track
Generate new album art for the song you're working on. The prompt starts from the track's style, and an AI prompt helper can write one for you. Apply the image you like and it replaces the track's artwork, while the audio stays exactly as it was. For reference images, other aspect ratios or upscaling, use the Album Cover Generator.
- Square artwork, applied to the track in one click
- Example covers you can reuse as a starting prompt
- Results also appear in your Album Cover Generator history
Extend a song with AI from the point you choose
Extend works as an AI music extender: it writes a new section for your song instead of looping what's already there. Write the lyrics for the new part yourself, or let AI continue them from the lines that come before. Use it as an AI song extender for an extra chorus, a bridge or an outro.
- Add a section at the end, or rework the ending
- The new section's length follows its lyrics
- The extended version is saved next to the original
Split a song into vocals, drums, bass and more
Stems uses AI to split the track into two stems (vocals and instrumental), four (vocals, drums, bass and other) or six, adding guitar and piano. Solo, mute, pan and rebalance each part in the mixer, then download the stems or render a version without one part, such as the vocals. To split a file from your computer, use the Stem Splitter or the Vocal Remover.
- Choose between the Lacuna Pro and Lacuna Basic models
- Download each stem as its own MP3
- Removing a part can reuse stems you've already split
Master a track and compare every version
Mastering polishes loudness, dynamics and tone by matching your mix to reference presets such as Balanced & Clear or Loud & Punchy. Each preset you pick becomes its own mastered version, and you can switch between the original and every master on one timeline. To match a reference song of your own, open AI Mastering.
- Readings for LUFS, true peak (dBTP) and loudness range (LU)
- Limiter on by default, or off to keep headroom
- Output as WAV (16- or 24-bit) or 320 kbps MP3
AI agents handle the busywork while you stay in the director's seat
Keep every result connected to its source, so the original is always in reach
How to make music with AI
Make a song with AI in four steps, from a first idea to a finished track.
Describe your idea
Tell the Music Agent what you want: a genre, a mood, a story, or lyrics you've already written. Ask for an instrumental if you don't need vocals. Have finished lyrics? Paste them into Lyrics to Song, or start from a one-line brief with Text to Song.
Get two directions
The agent drafts two directions for your idea, keeping what you asked for and varying what you left open, then starts generating the first. Adjust either one, or ask for something different.
Listen and compare
Play the takes on the canvas as they finish; most models return two per run. For more options, generate the second direction or switch models.
Refine, then release
Edit a section, remix, extend, split stems or master the track, then turn the finished song into a lyric video.
Words in time, visuals on the beat.
Sync lyrics to any song word by word, turn them into a lyric video, or give the track an audio-reactive visualizer for any screen.
