Taking and Saving Screenshots

How to capture and save screenshots with AI-powered visual descriptions.

BrainTube can capture screenshots and use AI to generate rich visual descriptions, making visual content searchable.

How to Take a Screenshot

  1. Click the BrainTube extension icon
  2. Select "Capture Screenshot"
  3. Select the area you want to capture (or capture the full page)
  4. The screenshot is saved to your Library

AI Visual Description

Unlike regular screenshots, BrainTube uses Gemini 2.5 Flash vision to analyze the image and generate a detailed description of what's shown, any text visible in the screenshot (OCR), key concepts and entities depicted, and contextual tags.

This means you can search for screenshots by describing what's in them — e.g., searching "architecture diagram" will find your saved whiteboard photos.

Use Cases

  • Capture diagrams from presentations or whiteboards
  • Save code snippets from editors or terminals
  • Document workflows with step-by-step screenshots
  • Archive social media posts before they disappear

Screenshot Groups

Multiple screenshots from the same session are automatically grouped together, making it easy to find related captures.

Tips

  • Screenshots are excluded from topic clustering to reduce noise
  • Add manual tags to screenshots for better organization
  • Use the detail view to edit or enhance the AI-generated description
