Runs on your machine, not our servers

Turn one video into every language your audience speaks.

Automatic bilingual subtitles, processed locally on your own computer — no cloud video uploads, no per-minute fees. Translate using your own DeepL/Google/Azure key, or the built-in free offline engine.

Import step in Polyglot Studio

Drag in a local video file — mp4, mov, mkv, or avi. These are real screenshots, not mockups.

Why it's different

Built for people who edit video, not upload it.

Runs locally

Your videos never leave your computer. Transcription and rendering happen entirely on-device — no cloud upload, no privacy tradeoffs.

Bilingual by default

Original and translated text, stacked cleanly in one caption block — not two competing subtitle layers fighting for space.

Pay once, own it

No subscription treadmill. Buy a license, use it on your own hardware for as long as you like.
