ThreadCast

ThreadCast turns any Reddit thread into a podcast.

Every text-to-speech app reads a thread in one flat robot voice, so a 40-comment thread becomes an unlistenable monotone wall. ThreadCast fixes that: each commenter gets their own on-device AI neural voice (up to 11), so the post and top comments play like a real conversation.

What it does:
• Multi-voice: a different on-device AI voice per commenter
• Comment control: pick which comments and how deep
• Queue + local save for offline listening
• Sleep mode: 10 ambient sounds + a fade-out timer
• Lock-screen, Bluetooth, and media controls, no account
• Full TalkBack support for eyes-free and screen-reader use

Private by design: everything runs on your device. No cloud, no account, no tracking, no ads, and it works offline (even on a plane).

Free vs Premium:
• Free: your phone's system voices, browsing, queue, comments, sleep mode
• Premium (live on Android): on-device AI voices + MP3 export, so you can drop any thread into any podcast app

Also free: a full-featured Chrome extension with the same multi-voice narration, four on-device engines, side panel, and sleep mode, and its AI voices are free too.
Coming soon to the extension: MP3 export and reading beyond Reddit (PDF, DOCX, EPUB, web articles, your own text).
