# AI video editor: trim, caption, and polish clips in the browser

> Edit clips from AI video clipping in a browser-based AI video editor: cut on the timeline, add captions, text, images, and transitions, clean up with AI tools, apply a brand kit, and export a new clip.

The AI video editor is a browser-based editor for polishing clips generated by AI video clipping, with no download, re-upload, or separate editing tool. You open a ready clip, edit it, and export the result as a new clip. The original clip is never changed.

What's new for customers:

* **Edit on the timeline**: play, split, delete a section, trim with grips, add an intro or outro, and navigate with the transcript.
* **Captions**: caption a clip with a preset drawn from the transcript, which follows every cut and stays in sync.
* **Text, images, and video**: overlay text and images, insert or replace video, and add transitions.
* **Clean up with AI tools**: remove silent pauses and filler words such as "um" and "uh" in one step, driven by the transcript, with captions kept in sync.
* **Brand kit**: apply your caption style, colors, logo, intro, outro, and clean-up settings to a clip at once.
* **Save and export**: save a draft to come back to, then export the edit as a new clip to publish or download.
