Subtitles in your browser. In any language. And every player on Mac.
Stack up to three subtitle tracks at once. AI translation and subtitle search coming soon.
One email at launch. No spam, ever.
Three tracks, one glance.
Overlay sits on top of whatever you're watching. No player to switch to. Just captions, exactly where they should be.
The boring parts?
Soon enough.
Today: bring your own .srt and sync with a hotkey. Coming next: AI finds the right files, translates to any language, and explains the tricky words — all while you watch.

Likely answered below.
What apps does it work with?
Anything that plays video on macOS — Netflix, YouTube, Apple TV+, Disney+, HBO Max, VLC, IINA, QuickTime, local files. The overlay is click-through, so your player handles play, pause, and fullscreen as usual.
Do I need to download subtitle files first?
No. AI finds them for you when you start watching. You can still import your own
.srt or .vtt if you have something specific —
both work, side by side.
Does syncing happen automatically?
Not at launch — sync is manual: one hotkey nudges all tracks until they line up with the video. AI auto-sync is on the roadmap for a later update, and manual will always stay available.
What about DRM-protected streams?
The overlay doesn't touch the video stream. It reads subtitle sources separately and draws captions on top of your screen — so Netflix, Apple TV+ and friends keep working exactly as they do today.
When's launch?
Launching spring 2026. Add your email above — one message the day it ships, nothing else.
