Cuts to the music
videoFn finds the beats and the changes in energy in your track. Claude times cuts and titles to them, so the edit lands on the beat rather than somewhere near it.
Claude video editor for Mac
Claude, now with a timeline.
Tell Claude who the video is for and what it needs to do. It plans the story, builds a first cut in videoFn and checks it over before you watch. Then you give notes.
videoFn is a Mac video editor that Claude or ChatGPT can drive. Describe the video, watch it come together in the preview and give notes. If you'd rather fix something yourself, the editor is right there.

What Claude was missing.
Ask Claude for a launch video on its own and you'll get a lovely script, a sensible shot list and no video. It knows what a good edit looks like. It just has nothing to cut with.
videoFn is the thing to cut with. It gives Claude a timeline, a transcript with a time for every word, the beats in your music, a preview it can look at and a renderer on your Mac. Claude does the editing and you do the directing.

Brief Claude the way you'd brief a person: what the video is for, how long it should be and where the files are.
It builds a first cut and checks it before you see it. The preview updates as it works, so you can step in the moment it heads somewhere odd.
Notes go in plain English, and each one builds on the last. Rather do a fix yourself? Drag it in the editor and tell Claude to carry on.
What Claude actually does in there.
Puts the words on screen
Speech is transcribed on your Mac with a time for every word. Claude turns it into captions and titles that arrive when someone says them, not a second later.
Finds a narrator
No one to read the script? Claude can generate a voiceover on your Mac and build the scenes around it. Nobody has to re-record the intro eleven times.
Marks its own homework
Claude checks rendered frames for text you can't read, cuts in the middle of a word and titles that leave too early. Then it fixes them and checks again.
Setting up takes about a minute.
Download videoFn and open it. The launch screen finds the Claude app and Claude Code, so click Connect next to whichever you use. Claude opens its extension installer, you glance at the permissions and choose Install. Claude Code users start a fresh session instead.
Start a new chat and ask for a video. That's the whole manual. You'll need a Mac with Apple Silicon.
Questions, answered.
- Which Claude apps work with videoFn?
- The Claude app for Mac and Claude Code. Click Connect in videoFn, choose Install when Claude asks, and either one can start editing. If you already use Claude on your Mac, you're most of the way there.
- Do I need a paid Claude plan?
- videoFn doesn't ask for a particular plan. A video takes a fair amount of back and forth, though, so higher usage limits make for fewer interruptions.
- What can I make with it?
- Launch videos, product demos, explainers, captioned talking heads, social clips, lyric videos. If it's a short video with a point to make, Claude can probably help. See some examples.
- Where does my footage go?
- The files stay on your Mac, where videoFn transcribes and renders them. Claude only sees what videoFn reports, such as transcripts and preview frames, and those go to Anthropic as part of your chat.
- Does it only work with Claude?
- No. ChatGPT works too, and so does OpenAI Codex. See edit video with ChatGPT.
The small print, in normal print.
Claude edits what you bring: footage, photos, music and words. It can make titles, charts and a voiceover from scratch, but it can't film the product shot you forgot to record.
You buy videoFn once. Claude runs on your own Anthropic account, so a long edit with plenty of notes uses some of your usage. And while Claude checks the details, whether the video is any good is still up to you.
