Free online video-breakdown tool: local files, Shot Detection, storyboard

Updated 19 Sep 2026

If you do not want to install software first, and you only need to drop in a local file for frame stepping, Shot Detection, and storyboard work, use CutGo Studio on the web. No install, entirely free, no sign-in, processed in the browser. It includes a program monitor, waveform, full timeline, shot list, and Storyboard Desk. It is not a no-install timeline for YouTube or TikTok originals—those need the extension.

Local files only. Not a downloader. Not a full NLE. The homepage covers web Timeline; this page covers Studio on the web.

What to click

  1. Open CutGo Studio on the web.
  2. Drag a local video into the program window.
  3. Frame-step, set In/Out, run Shot Detection.
  4. Organize on Storyboard Desk. Optional AI Image Analysis with your own key.
  5. Projects autosave in this browser. Clearing site data or switching machines drops them unless you export.
