What's a fact that sounds fake but is actually true?
Threads, now a podcast.
Reddit, read aloud on your phone.
Built for listening, on your phone
Everything that matters happens on your device.
- Free
A voice for every commenter
ThreadCast hashes each username to a consistent voice, so the same person always sounds the same across every thread. Long discussions read like a real conversation instead of one flat monotone.
- Premium
Local AI neural voices
Premium unlocks on-device neural voices (Lite, Plus, and Studio) that read far more naturally than your phone's system voices. Nothing streams; every voice renders locally. System voices stay free.
- Premium · v1.2
Save a thread as an MP3
Export any thread to an MP3 with chapter marks and cover art, then play it in any podcast app, send it to a friend, or keep it for the flight.
- Free
A podcast-style queue
Queue threads, drag to reorder, and let them auto-advance. Queued posts and their comments cache on your phone, so playback keeps going on the subway or the plane. Lock-screen and Bluetooth controls included.
- Free
Sleep mode
Slow the narration over one of ten ambient soundscapes, or add your own. Set a fade timer and the screen goes dark. The quietest way to end a scroll.
- Free
Private and on-device
No account, no tracking. Reddit content is fetched from Reddit's public API to your device, and the AI voices run 100% on your phone, so nothing you listen to ever leaves it.
On-device AI voices
Pick your voice. It runs on your phone.
Premium unlocks three neural engines, from light and fast to studio quality. Browse and preview the voices, then let author-aware narration give every commenter their own. Everything synthesizes locally, with no cloud and no signal needed.
- Lite, Plus, and Studio engines, all on-device
- Up to 11 distinct English voices to assign
- Downloads once, then runs fully offline
Drift off to a thread.
Slow the narration over one of ten ambient soundscapes, or add your own. Set a fade timer and the screen goes dark while the audio eases to silence. The quietest way to end a scroll, free on Android.
- Ten ambient soundscapes, plus your own track
- Independent voice and ambient mixing
- Fade-to-silence timer on a dark screen
Built to be heard, by everyone.
ThreadCast ships full TalkBack support on Android. Every control is labeled, every screen is navigable by screen reader, and listening is the whole point of the app. Accessibility is the product, not a setting bolted on at the end.
Every control labeled
Transport, queue, comment selection, and settings all announce clearly under TalkBack.

Wait until you hear about their blue blood — copper-based hemocyanin instead of iron.
OP here — so it literally bleeds blue? That sounds made up.
Bright blue when oxygenated — hemocyanin just carries oxygen with copper instead of iron.
And they can taste with their suckers. Evolution went absolutely wild on cephalopods.
Taste AND touch with the same suckers feels like a cheat code.
About 10,000 chemoreceptors per sucker — they basically see flavour.
Three hearts too. Two pump blood to the gills, one to the rest of the body.
They edit their own RNA on the fly to adapt to cold water — basically rewriting their own code in real time.
