Key Features

  • Local AI Speech Generation: High-quality, natural-sounding voices powered entirely on-device (Kokoro-82M, ~310MB one-time local download).
  • PDFs Read In The Right Order: Open any PDF, including local files on your own machine. Two-column papers read down one column and then the other, running headers and footers are left out instead of interrupting a sentence, and bullet lists read as lists.
  • Read Exactly What You Want: Right-click to read the whole page, just your selection, a single section, or from any point onward.
  • Smart Skip Extraction: Automatically strips clutter, ads, cookie banners, and navigation menus.
  • On-Page Controls: A compact player bar on the page itself — play, pause, skip a sentence — without opening the popup.
  • One-Click MP3 Export: Generate offline audio files in one click to listen anywhere.

Frequently Asked Questions

Does Audister work offline?

Yes. After a one-time model download of about 310MB, the natural AI voices run entirely on your own computer — no internet connection is needed to read a page.

Do I need an account to use Audister?

No. There is no sign-up and no login. Install the extension and press Alt+R on any page.

Is there a subscription?

No. Audister is free to use with your built-in system voices, and the local AI voices are a single one-time purchase of $19 with no recurring fees.

Can Audister read PDFs aloud?

Yes. PDFs open in a built-in reader that highlights each sentence as it is read, including PDF files stored on your own computer.

Is my reading data sent anywhere?

No. Page text is extracted and spoken on your own machine. Audister has no analytics and uploads nothing, unless you deliberately connect your own cloud API key in the options page.

Which browsers does Audister support?

Chrome 124 or newer, and Chromium-based browsers that install extensions from the Chrome Web Store.
