Privacy-First Video Translation: Only Audio Ever Leaves Your Device

Most translation tools upload your whole video to a server. SublyAI is built the opposite way: privacy is the default, not an add-on.

Your video never reaches the AI

The video file is processed locally in your browser. Only the extracted audio track is sent for speech recognition.

Audio over a signed URL, then deleted

The audio is stored in ephemeral storage behind a signed URL. No one else can access it — only you. As soon as transcription finishes, the audio is deleted automatically.

Client-side rendering is faster

Burning subtitles into the video runs in your browser via WebCodecs — no cloud render queues to wait in. Most videos finish in about 30 seconds.

And it is free to start

You get 15 minutes of AI processing free on registration, then pay-as-you-go credits that never expire. No subscription, no commitments.
