Cut it yourself. Or say what to change.
A real timeline editor that runs in your browser — clips, text, captions, music, overlays — and exports an MP4. The unusual part: an AI assistant can work the very same timeline for you, and you can take the mouse back at any point without losing anything it did.
The parts of a cut, all here.
Nothing to install. Bring a file from your computer or paste a link, and work on a timeline that behaves the way you expect one to.
Trim, split, reorder
Drag clips, cut at the playhead, nudge a boundary by a single frame.
Text and titles
Place words on the frame, choose the font from your own uploads, time them to the second.
Automatic captions
Speech turned into subtitles you can edit afterwards, line by line.
Music and levels
Add a track, duck it under speech, fade it in and out along a curve.
Overlays, motion, colour
Logos and stickers, pan and zoom with keyframes, transitions, colour adjustment, fit and crop.
Export MP4
Preview first, then render the real file — including a vertical profile for shorts.
An assistant that edits, not one that guesses.
You can connect an AI assistant — Claude, or another one that speaks MCP, a standard way for assistants to use outside tools — and ask it to do the tedious parts: "cut the first eight seconds", "put the title over the opening", "add subtitles". It does not generate a video and hand you a mystery. It performs the same named edits your own mouse performs, on your timeline, one at a time.
You can see what it did
Every edit is a named entry in the project's history — read it, and undo any of it.
You can take over
Open the project and keep cutting by hand. Nothing is locked to whoever made the edit.
You hold the key
An assistant connects with a token you create and can revoke in a click. No token, no access.
It is optional
The editor is complete without it. Ignore this section and nothing is missing.
Setting an assistant up is a copy-and-paste of one config block — the tool reference spells out exactly what it is allowed to call.
From a raw file to a finished MP4.
Bring the footage
Upload from your computer, or paste a link and let the server fetch it.
Cut it
Trim, arrange, add text, captions, music and overlays on the timeline.
Watch it back
Preview before rendering, so a mistake costs seconds instead of minutes.
Export and download
Render the MP4 and save it. What renders is what you saw.
What this is not, yet.
Worth knowing on the way in rather than on the way out. Access is free while the service is in preview, and free has edges.
Daily limits
Renders, previews and imports are capped per day and per account, and long or very high-resolution sources may be refused. The editor tells you where you stand before it refuses, not after.
Finished files expire
Exports are kept for about a day, downloaded footage for about two. Download anything you want to keep — this is an editing workspace, not storage.
One render at a time
Rendering is real work on a real machine. At busy moments your export waits in a queue rather than failing.
Desktop browser
A timeline needs room and a pointer. There is no mobile app, and a phone screen is not the place to use this one.
Your projects and uploads are yours: you can delete any of them, or the whole account, from inside the app. The privacy policy says what is stored and for how long.
