ThreadCast turns any Reddit thread into a podcast.

Every text-to-speech app I tried read a thread in one flat robot voice, so a 40-comment discussion became an unlistenable monotone wall. So I built ThreadCast: it plays the post and the top comments aloud, and gives each commenter their own on-device AI voice, so the thread actually plays like a conversation.

The whole thing runs on your phone. No cloud, no account, nothing leaves your device, and it keeps working offline once a voice is downloaded. Built for long threads you'd rather listen to on a commute or at the gym than read on a small screen.

Free to start with your phone's system voices, browsing, queue, comment control, sleep mode with 10 ambient sounds, and lock-screen controls. Premium adds the on-device AI voices (up to 11) and MP3 export, so you can save any thread for any podcast app.

Live now on Android, with a full-featured free Chrome extension too (multi-voice, four on-device engines, side panel, sleep mode). MP3 export and reading beyond Reddit are coming to the extension.

I'm a solo founder building this under Pixel Labs. What would make you actually listen to a thread instead of scrolling past it?
