What Video Goblin does

Video Goblin is a video editing application. You import video, audio and image files, arrange them on a multi-track timeline, trim and split clips, apply effects, transitions and colour correction, add titles and captions, and export the finished result as an MP4 file. All editing, preview and rendering happen locally in your browser — your footage is never uploaded to our servers.

What makes it different is the built-in AI agent. Instead of performing every edit by hand, you can describe what you want in plain language and the agent carries it out using the same edit operations available to you. It runs on an OpenAI or Google Gemini API key that you supply and control.

Signing in with a Google account is required for two features only: exporting a video and using the AI agent. Connecting Google Drive is entirely optional, and is used so you can import footage you select from your Drive and save your project files there to continue an edit on another computer. Everything else works without an account.

The agent

Say it. It edits.

Describe the change. The agent performs the same edit operations you would — every one typed, undoable, and recorded against its name.

  • It cannot do anything you can't
  • Undo works on its edits too
  • Every change says who made it, and why

100% in your browser
0 bytes of footage uploaded
0 trackers or analytics

Your media and projects live in your own browser. Editing, preview and export all happen on your machine — we never receive your footage.

Optional

Google Drive, if you want it

Import footage you pick, and save projects so you can pick an edit back up on another machine.

  • You choose the files, in Google's own picker
  • Projects saved to a folder the app creates
  • Uses drive.file — the narrowest scope there is. It cannot browse or read anything else in your Drive
  • Files move browser-to-Google, never through our servers
