Detect[01]
Detected per clip
Prewatch listens to each clip and picks its language, so a folder can mix an English piece to camera with a Spanish interview and a Japanese street scene.
Languages
Transcripts in 100 languages
Prewatch transcribes your footage on your Mac in 100 languages, from Spanish, German and Portuguese to Japanese, Hindi and Arabic, and adds an English translation, so Claude or ChatGPT can find a line whatever language it was said in.
14 days free, then $59 a year or $7.99 a month. Works with your Claude or ChatGPT plan; timelines need DaVinci Resolve Studio 21.1+. Clip descriptions are optional and use your own API key, billed by Anthropic or OpenAI.
How it works
Every language, the same way
Transcription and speaker recognition run on the Mac in every language. Nothing is uploaded and nothing is charged per minute.
Set[02]
Or set for the folder
If you know the language, set it once for the folder. Every clip is then transcribed in it, including clips whose language was too unclear to detect.
Translate[03]
Translated into English
Speech in another language gets an English line beside each original line, with the same times. Your AI can search either.

Is it as accurate in every language?
No. Accuracy follows how much of each language the recognizer (Whisper) learned from: it is strongest in widely spoken languages and weaker in languages with little recorded speech. Spanish, French, German, Portuguese, Japanese, Chinese and the other major languages transcribe well. For a rarer language, try a few clips during the free trial.
Does transcription cost anything per minute?
No. Transcription runs on your Mac's GPU, in every language, with no account and no per-minute fee. The speech model is downloaded once, the first time a folder is transcribed.
How does the English translation work?
With descriptions on, your own Claude or OpenAI key translates the transcript line by line, by meaning rather than word for word, for about $0.0005 a minute of talk. Without a key, Whisper translates on the Mac instead: free, but rougher.
What if one clip mixes two languages?
A clip is transcribed in one language: the one detected, or the folder's language if you set it. Speech in a second language in the same clip may come out less accurate, so keep the folder's language on the one most of the footage is in.
Is any audio uploaded?
No. Transcription runs on the Mac and no audio or video leaves it. Only with descriptions on does transcript text go to Claude or OpenAI, with your own key, to be translated and described.
