VideoContext App — Chrome Extension

Turn screen recordings into AI-ready context. Record your screen, extract the most useful frames, and paste them into Claude, ChatGPT, or Gemini.

Video isn't a supported input in any major LLM today. VideoContext records a portion of your screen, extracts the most useful frames as PNGs, stitches them into a single grid image, and copies that to your clipboard. One paste delivers the whole sequence to the model.

The extension is free and open source (MIT). Find the project at videocontext.app.

Features

• Tab / Window / Screen capture via Chrome's native picker.
• Optional area select — draw a rectangle to crop every frame.
• Three duration presets, all targeting 10 frames:
  • Quick — 5 seconds at 2 fps.
  • Standard — 10 seconds at 1 fps.
  • Slow — 20 seconds at 0.5 fps.
• 3-2-1 countdown before capture starts.
• Copy as Grid — selected frames stitched into one watermarked PNG and written to the clipboard. One paste sends the whole sequence.
• Save PNGs (zip) — bulk export selected frames as frame-001.png, frame-002.png, … inside a single archive.
• 100% offline. No accounts, no servers, no telemetry. Frames live in browser memory and are dropped when you close the widget.
