Most translation tools upload your whole video to a server. SublyAI is built the opposite way: privacy is the default, not an add-on.
The video file is processed locally in your browser. Only the extracted audio track is sent for speech recognition — the original footage never leaves your device.
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.
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.
You get 15 minutes of AI processing free on registration, then pay-as-you-go credits that never expire. No subscription, no commitments.
