Questions

How do I turn a video into subtitles?

Sign up and upload a video or audio file. It’s transcribed into timed subtitles automatically, and you can ask for AI subtitles and an AI translation at the same time. Review online, then export SRT, VTT or TXT for your editor or your upload.

Does AI subtitle translation keep the original timing?

Yes. A large language model translates with the context in mind, and the translation is aligned word by word to the original audio, so you can check the two line by line.

How am I charged?

Transcription is charged by the length of your footage, 10 credits a minute; AI translation by usage; AI subtitles cost nothing extra. You see an estimate before you submit.

Am I charged when something fails?

No. Each step is charged only when it succeeds. If a translation doesn’t finish, you keep the transcript, and translating again doesn’t charge for the transcription twice.

Is the video I review with uploaded?

No. The local file you open while reviewing only plays in your browser, next to the subtitles.

Can I use it without a plan?

Yes. Buy credits at the base price or redeem a gift card. A plan adds credits every month and makes extra credits cheaper.
