AI captures
Your agent takes a screenshot and uploads it through BlindSpot's MCP server.
You annotate
Open the URL on your phone. Draw, circle, arrow, and comment with touch.
AI fixes
The agent reads your annotations — shapes, coordinates, comments — and updates the code.
You're on your phone, remote-controlling Claude Code. You tell it to fix a layout bug. It takes a screenshot… but you can't see it. The terminal doesn't render images. You're debugging blind.
BlindSpot gives your screenshots a shareable URL. Open it on your phone, draw circles and arrows, add comments like "move this left". Your AI reads the structured feedback and fixes the code.
Workflow
Three steps, zero context switching
AI uploads a screenshot
Your AI agent captures the screen via Playwright or any screenshot tool, then uploads through BlindSpot's MCP server. A secure, temporary URL is returned.
"Take a screenshot and upload it for me to review"You annotate on your phone
Open the URL on your phone browser. Draw arrows, circles, rectangles with touch. Add comments to each shape — "change this color", "remove this button". Touch-optimized editor, zero learning curve.
AI reads and fixes
Your agent calls get_annotation to read structured data — shape types, coordinates, and your comments. It knows exactly what to change.
