Turn long text into an audiobook

Paste your text or drop a Word file. Lines that start with Chapter or # begin a new chapter. Authors use this to hear a draft before recording it properly.

Or drop it here. PDF, EPUB, DOCX, TXT or Markdown.

Or paste text instead

The first time, your browser fetches the voice (about 90 MB) and keeps it. After that it starts in seconds.

Want subtitles or a transcript instead? Transcribe audio free, also in your browser. Building an app? The text to speech API takes OpenAI and ElevenLabs request formats, no account needed, card from $1.

How it works

Questions

Is it really free? Yes. Your own computer makes the audio, so there is no account, no monthly hour limit and nothing to pay.

Is my book uploaded? No. The file is opened and read aloud inside your browser. It never reaches our servers.

How long does it take? It depends on your computer, because your computer does the reading. A recent laptop handles a chapter in a few minutes; an older or busy one takes longer, so start with a chapter or two. Tick Graphics card mode if you see it: it is usually much quicker. The page shows the time left, and you can stop and carry on later in the same tab.

Which files work? PDF, EPUB, Word (DOCX), TXT and Markdown, or pasted text. Scanned PDFs that are only pictures of pages have no text to read; run them through text recognition first.

Can I keep the tab in the background? Yes, but keep it open and the computer awake. Some browsers slow down background tabs, so a visible tab finishes sooner.

Which languages? English, with American and British voices. More languages are planned.
