What you get

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.
