AI Video Editor Online

Tell StarCut what the cut should feel like. The agent trims clips, places captions, adds graphics and music, and leaves everything on a timeline you can open and adjust. It all runs in your browser.

Enter a prompt before starting creation.

Runs in a modern browser. Nothing to install.

An editor that makes the first pass and lets you finish it

01

Describe the cut, get a timeline

Write what you want in plain language: the length, the pace, the mood, and what to keep. The agent lays the clips on video, graphics, and music tracks instead of rendering a flat file.

Every cut, caption, and sticker is a separate clip you can move, trim, or delete.

Generate what the footage is missing

Need a b-roll shot, a sound effect, a sticker, or a title card? Ask for it in the same chat. StarCut calls video, image, audio, and motion graphics models and drops the result into the project.

No install, any machine

StarCut is a browser video editor: no download, no hardware upgrade, nothing to keep updated. Open the project again and keep working where you left off.
