Reports, papers, and half the books people actually own live in PDF. Converting a PDF to an audiobook shouldn't mean a subscription or a robotic voice — here's the free, open-source way that produces a real listenable series.
Generation runs about 10x faster than playback: upload a PDF from your phone's browser and the first episode is ready before you've laced your shoes; a 300-page PDF finishes in the background while you listen.
Read-aloud apps play one document while the screen is on, and lose your place when it locks. A podcast-feed pipeline gives you lock-screen controls, per-episode resume, and a queue — the difference between "text to speech" and an actual audiobook.
Not directly — scanned pages have no text layer. Run OCR first (e.g. with ocrmypdf), then upload the result.
They're read as text, which works for prose-heavy documents. Heavily mathematical papers are better skimmed visually and listened to for the prose sections.
Nothing per book: the pipeline is AGPL open source, storage fits Cloudflare's free tier, and the default neural voices are free for personal use.
