Lecture notes and textbooks
Turn a reading list into something you can review on the walk to class.
Upload a PDF, check the text, then turn it into MP3.
Drop in a text PDF or a scan, up to 500 pages. Headers, page numbers and footnotes are left out, so you don't hear them read aloud.
Read what will be spoken, chapter by chapter. Delete anything you don't want, fix a name, or untick whole chapters. You only pay for the text you keep.
Choose one of 30 voices. Every chapter becomes its own MP3 you can play here or download, one by one or all at once.
Anything you'd rather hear than read on a small screen.

Turn a reading list into something you can review on the walk to class.

Get through long documents on your commute, or send the audio to your team.

Hear your own draft read back, or make a chapter-by-chapter listen of a public-domain book.

Citations and footnotes are skipped, so a research paper reads like an article.
Upload the PDF and wait while it's read, about two seconds a page. Check the text, choose a voice, tone and pace, then press Generate audio. Each chapter becomes its own MP3 in your history.
Reading the PDF and seeing the text is free with an account, up to 100 pages a day. Generating audio costs 5 credits per 100 characters, and free accounts get 120 credits a month, about 2,400 characters. Listening is free; downloads come with paid plans.
A typical page is about 2,000 characters, so 100 credits a page. A 300-page book is about 30,000 credits. Your cost is shown before you generate, and you can pick just the chapters you want.
Yes. Scans and image-only PDFs are read directly, with no separate OCR step. Old or faded pages can have the odd mistake, which is why you see the text before you generate.
Yes. Reading the PDF comes first and costs nothing. You get the text back chapter by chapter, and you can change or delete anything, or untick whole chapters. You're only charged for what you keep.
Yes. Once a chapter is generated, press play and it's read out loud on this page, on a computer or a phone. It doesn't highlight words as it goes. You get audio files instead, and on a paid plan you can download the MP3s and play them anywhere.
Here they're the same thing. PDF text to speech, PDF to speech and PDF TTS all name the step where a voice reads the text, and PDF to audio is what you end up with: an MP3 for each chapter.
Yes. Each chapter becomes its own MP3, so a PDF to audiobook conversion gives you a folder of chapters to play in order, rather than one long file. Download them all at once as a ZIP on a paid plan.
Yes, on a paid plan. Each chapter downloads as MP3 or WAV, or you can get them all at once as a ZIP. This tool gives you files to keep rather than a reader you have to stay inside.
Up to 500 pages and 100 MB per file. There's no limit on how much of it you turn into audio at once; long chapters are split so each MP3 runs about 30 minutes at most.
Headers, footers, page numbers, footnotes and reference lists are skipped. Each table row is turned into a short sentence you can follow by ear, which makes those pages a little longer. Pages where this happened are flagged so you can check them.
Only for the words on the slides. Slides usually have very little text, and images and charts are skipped, so the audio will be short. We warn you when a PDF has almost nothing to read.
More than 130, including English, Spanish, French, German, Japanese, Korean and Chinese. You don't choose one: the voice reads whatever language the PDF is written in.
The original file is deleted as soon as it's been read. The text stays in your account so you can edit and generate, until you delete it.
Upload a PDF, check the text and turn it into MP3. Reading it costs nothing.
