// 01 — Private by design
Your footage never touches a server.
Most web editors sneak your video to the cloud. We run the whole thing locally, the AI only ever sees your words, not your pixels.
A
Zero uploads
Decode, edit, export, all on your machine. Kill your wifi mid-edit? Still works.
B
Safe for unreleased work
For footage that legally can’t land on someone else’s server. Teams get it.
C
No upload wait
No 400 MB progress bar staring at you. Drop it and go.

Auto-captions. 19 languages. Nothing uploaded.

19 languages, auto-detected
It works out what it is hearing on its own. English, Spanish, Japanese, Hindi, Arabic, Chinese and a dozen more, no setting to find first.
B
Nothing is uploaded
Whisper runs on your machine, not a server. Your audio, the transcript and the render all stay put. Works with the wifi off.
C
Fix the words before you burn
Every line is editable. Correct a misheard name, drop a line, re-time it. What you read is what gets rendered.
D
Place it, style it, or skip it
Drag the caption onto a real frame to place it. 7 styles, three sizes, six colors. Or take the .srt and keep the video clean.
// Word-level timing from Whisper. Burned in with libass, so they look the same everywhere you post them.
// 05 — Advanced editor
When you want the timeline, it's right there.
The prompt bar handles most of it. For the rest there's Studio: a real multitrack timeline in the same tab, with frame-accurate trims and an agent that works it with you.
Get the desktop app →// Export from Chrome, or hand it to the desktop app for the native render.
01
Multitrack timeline
Video, text and audio lanes. Drag, trim, split, ripple. Filmstrips and waveforms right on the clip.
02
Cut by deleting words
The transcript is the edit. Select a sentence, delete it, the clip cuts. Tighten every silence in one pass.
03
The agent proposes, you approve
Ask for a change and it drafts the actions against a scratch copy. Review the diff, then apply or throw it away.
04
Yours to keep
Save the whole project to a .unocut file, assets included. Open it on another machine. No cloud project, no lock-in.

// 06 — Folder suite
Point it at a folder. Walk away.
For the shoot with 40 clips in it, not the one clip you dragged in.
01
Apply to all
One prompt, every clip in the folder. They queue up locally and come back edited, one at a time, so your machine keeps up.
02
New files, edited on arrival
Save the rule once. Sync the folder and anything that landed since gets the same treatment, without you asking again.
03
Clips that talk to each other
@-mention any clip in the project to stitch it onto the end, drop it in picture-in-picture, or borrow its audio.
// Folder access uses the File System Access API: Chrome, Edge and the desktop app. The folder stays on your disk, we only read the clips you open.
// Nothing is destructive
Every prompt is a version you can go back to.
Each edit forks the one before it instead of overwriting it. Step back through the tree, branch off an earlier take to try something else, and download any version you like. The clip you started with is still sitting there, untouched.
// Just say it
If you can describe it, we can cut it.

// 09 — FAQ
Questions, answered.
Yep. Supercut decodes, edits, and exports in your browser with WebAssembly. The only thing that leaves your device is your text prompt so the AI knows what to do. Unplug mid-edit? Still works.
Nope. Any modern browser. Drop a clip and go. There is also a native desktop app if you want it.
Yes. Supercut is on the Mac App Store, and there is a notarized .dmg for Mac and an installer for Windows on the downloads page. Same editor, native 4K playback, and it works with no connection at all.
Whisper transcribes your audio on your own machine, so nothing is uploaded. You get word-level timing, 19 languages plus auto-detect, and an editable transcript, so you can fix a misheard word before anything is burned in. Then drag the caption onto a real frame of your clip to place it, pick one of 7 styles, three sizes and six colors, and burn it in. Or just download the .srt.
Yes. The Editor tab is Studio, a multitrack timeline with video, text and audio lanes, frame-accurate trims, splits and transitions, filmstrips and waveforms on the clips, and full undo. You can cut by deleting words from the transcript, ask the agent for a change and review its proposal before applying, and save the whole project to a .unocut file.
Yes. Connect a folder and run one prompt across every clip in it, or save the rule so anything new that lands gets the same edit when you sync. Folder access uses the File System Access API, so it needs Chrome, Edge or the desktop app. The folder never leaves your disk.
Nothing is destructive. Every prompt forks the version before it instead of overwriting it, so you can step back through the tree, branch off an earlier take, and download any version. Your original clip is always still there.
