The Mac screenshot tool
your AI can read
Annotate any app, then send the screenshot, every region crop, and a structured manifest to Claude, ChatGPT, or Cursor — in one paste. So it fixes the right thing the first time — fewer iterations, fewer tokens. One-time, on-device.
One paste = full screenshot + every region crop + this manifest.
One click — send screen context to your favorite apps, and speak your coding agent's language over MCP
One tool from capture to context
Screenshot, annotate, record, and redact. Everything your agent needs to see, in a format it can read.
Annotated screenshots
Drag regions, label them, submit. Your agent gets the full screenshot, every region crop, and a structured manifest in one paste.
Record like Loom
Record a window or the whole screen with your camera bubble. Click to pick the target, a red border shows what is captured.
Multilingual OCR
Pull text out of any region. On-device recognition handles many languages and writing systems, straight to your clipboard.
MCP agent tools
Twelve tools any MCP agent can call. Capture, annotate, record, and read text, programmatically.
✓ screenshot + recognized text
Semantic recording
An on-device model turns a recording into a short, agent-readable summary instead of raw frames. Your agent reads meaning, not megabytes, saving tokens and time.
Spotlight redaction
Blur everything outside your pins before sharing. Keep the bug sharp, hide the secrets.
Fewer iterations, fewer tokens
Exact crops plus a spatial manifest mean your agent fixes the right thing the first time — not the fifth. Fewer round-trips means less guesswork, and less token churn.
How it works
Capture
Press the hotkey, drag regions over what matters, type quick labels.
Context
Submit and paste. Your agent gets the screenshot, crops, and the spatial manifest.
Act
It reads the manifest, sees the crops, and fixes the right thing. No more guessing.
