Problem[01]
“Let me start that again”
You restart a sentence until it comes out right, ten times in a bad lesson. Finding the last complete attempt means listening through every false start before it.
For Educators and course creators
The clean take of every lesson, found for you
A batch recording day: lesson after lesson to camera, a restart after every stumble, screen recordings in between. Prewatch transcribes it on your Mac, so you can ask for the last clean take of each section in module 3.
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.

Problems
What slows Educators and course creators down
Problem[02]
Fifty files named by date
A batch day leaves dozens of recordings named by date and number. Matching them to the modules and lessons in your outline happens from memory, or in a spreadsheet nobody keeps up.
Problem[03]
Captions still to do
Students expect captions on every lesson. After a week spent finding takes and cutting them, each lesson still needs a subtitle file someone has to make and check.
What Prewatch gives you
Your footage, already watched
Prewatch indexes every clip on your Mac, so Claude or ChatGPT knows what is in your footage and can build the cut with you in DaVinci Resolve Studio.
| What you get | Where it runs | What it does for you |
|---|---|---|
| Every take transcribed | On your Mac | Your words with the time of each one, so the assistant can line up your attempts at the same sentence and pick the complete one. |
| Restarts easy to spot | On your Mac | Quiet stretches of two seconds or more marked in each recording, the natural seams between one attempt and the next. |
| Subtitle files | On your Mac | Each recording's transcript also written as WebVTT and SubRip, the standard caption formats, a head start on the finished lesson's captions. |
| English subtitles too | On your Mac | Teach in Spanish, German or Japanese and each recording also gets an English translation, as text and as subtitle files. |
| Recordings by topic | Claude or OpenAI | A short description of each recording, so “the one where I explain pricing tiers” finds the right file. With your own Claude or OpenAI API key. |
| Lessons built in Resolve | Your AI app | Your assistant lays the chosen takes on a timeline in DaVinci Resolve Studio 21.1 or later, in the order of your outline. |

Ask it
One question instead of a day of scrubbing
You ask in Claude or ChatGPT. Prewatch answers with the clips, the seconds and the timecode, and your assistant builds the timeline in DaVinci Resolve Studio.
01
Which recording covers connecting the payment provider?
The recordings where you explain it, with the transcript lines and the time each one starts.
Your AI app02
In lesson 4, keep only the last complete take of each sentence.
In and out points for each kept take, with the false starts left out, and the transcript of what stays.
Your AI app03
Assemble module 2 in the order of the outline I pasted.
A timeline in DaVinci Resolve Studio with the best take of each section, in outline order.
Your AI appDoes it work with screen recordings?
Yes, if they are MOV or MP4 files macOS can decode, as the Mac's own screen recordings are. Your narration in them is transcribed like any other clip.
Can it remove my ums and pauses?
Prewatch doesn't edit audio. It gives the assistant the time of every word and the quiet stretches, so it can set in and out points around false starts; the cut itself is made in Resolve.
Can I teach in a language other than English?
Yes. Whisper detects the language of each recording and transcribes it in that language, or you can set one language for the whole folder. Recordings not in English also get an English translation.
Does it work with the free version of DaVinci Resolve?
Building timelines by chat needs DaVinci Resolve Studio 21.1 or later, whose built-in MCP server lets your assistant work in Resolve. With the free version you can still index your footage, search it and ask Claude or ChatGPT about it, then place the clips yourself. A file handoff that the free version can import is planned.
How does the free trial work?
Prewatch is an App Store subscription with a 14-day free trial: $59 a year or $7.99 a month after it. You manage or cancel it in your Apple Account's subscription settings; cancel before the trial ends and you are not charged.
