How it works

Built around Japanese
Qwen3-ASR handles the Japanese recognition, DeepSeek handles the English translation.

About ten minutes per two-hour video
End-to-end — audio extraction, Japanese transcription, and English translation.

No charge for cached audio
We cache transcripts by audio fingerprint. If your audio matches one we've already processed, you get the result instantly — no credit, no wait. Renamed files still match.

Credits roll over
Pro credits carry to the next month, up to a 20-credit cap. A slow month doesn't cost you what you paid for.

Auto-subtitle new files in a folder
Install the subsrip CLI, pick a folder on your computer, and anything you save there gets transcribed automatically. Up to three files at once.

Re-download any time
Your subtitles stay in your account. Pull them back down from any device.
Try it on one of your files.
Five free translations to start. No card.
