Turn PDFs into audiobooks in your browser. Upload a PDF, listen to it, and follow along with highlighting.

Live: https://audiobook.vedgupta.in/

What it does

• Upload PDFs and keep them in your library
• Listen with the offline neural voice or your browser voice
• Follow word and sentence highlighting while listening
• Click text to start reading from that point
• Resume where you left off
• Read scanned PDFs with OCR
• Works locally in the browser without API keys

Run locally

bun install
bun run dev

Open http://localhost:5173, upload a PDF, and press play.

Build

Requires Python 3 only when regenerating the voice model locally. The pre-built ORT bundle in public/kitten-model/ is committed so Cloudflare Pages can deploy without Python.

To rebuild the model (after a Kitten update):

rm -rf public/kitten-model .venv
node scripts/fetch-kitten-model.mjs

Then commit the updated public/kitten-model/ files.

bun run build
bun run preview
