Use Screenshots And Screen Context
Capture screen context when the question involves code, a diagram, slide, terminal, or browser page. The analysis provider may receive the actual screenshot image, as well as extracted context.

Choose The Capture Scope
Section titled “Choose The Capture Scope”| Screenshot | How to use it |
|---|---|
| Active window | Enable Capture active window only in Settings → Screenshot. |
| Whole screen | Turn that setting off; the capture can include the menu bar, Dock, and other visible content. |
| Region | Use Capture Region Screenshot or its shortcut, then select the area you need. Both direct-download and Mac App Store builds support regions. |
| Before analysis | Enable Take a screenshot before starting analysis, also available in Quick Settings. |
Capture And Ask
Section titled “Capture And Ask”- Grant screen recording permission.
- Put the relevant content on screen and choose the capture action.
- Confirm the screenshot entry appears in the current session context.
- Click Ask or type a question describing what to examine.
A region capture can start analysis immediately when the active profile’s behavior enables it. Otherwise, capture and analysis are separate actions.
Earlier Screenshots
Section titled “Earlier Screenshots”ExtraBrain can search screenshot evidence within the selected session. Ask a specific question such as “Compare this error with the screenshot from earlier in this session.” Search is session-scoped; it does not mean every past screenshot is attached to each request or that another session is automatically available.
Remove Unwanted Images
Section titled “Remove Unwanted Images”Delete an accidental screenshot from its entry controls. Review the image before using cloud analysis. Deleting local history does not retract content already sent to a cloud provider or analytics service.
