What SlimSnap does

SlimSnap is a free screenshot and screen recording app for Mac and Windows. Every capture saves the image plus a JSON file with each piece of on-screen text, its position and color, and any arrows or boxes you drew, linked to the element they point at.

Why: coding agents like Claude Code and Cursor read screenshots as downscaled images, so small text blurs, and they can't watch a video at all.

Features:

  • Region, window and scrolling capture with autoscroll

  • Screen recording with voice: talk while you record, your words become text on your machine, the video saves as MP4

  • Interactions: every click that changes the screen becomes a step (dashboard, click "Invoices", invoice list), so an agent can follow the exact path to a bug. Keystrokes are never recorded

  • Annotations: Arrows, boxes, highlights and text, on screenshots and recordings

  • Copy as PNG, as JSON, or both

  • MCP connector for Claude Code, Claude Desktop and Cursor

  • Works offline, nothing is uploaded

Free, no account, signed for Mac and Windows.

Turning screenshots into JSON for coding agents sounds useful. Does SlimSnap preserve layout coordinates, text, and component relationships so agents can identify UI issues without processing the original image?

Yes for coordinates and text. Every element comes with its text, a bounding box and a color, and your marks (arrows, boxes) are linked to the element they point at. It's a flat list though, no parent/child tree, so component relationships are inferred from positions. The agent can work from the JSON alone for text and layout, the image is there if it needs to look closer.
