Your second brain,
one keystroke away.
Press it anywhere — Ctrl+Brain captures the text, image, or screenshot in front of you, reads it on your Mac, and saves it to your second brain.
Three steps, one shortcut
01 — 03
Capture
Text, images, and screenshots — saved with one global shortcut, from anywhere on your Mac.
Understand
Apple Vision OCRs the pixels and a local model describes them. Everything stays on-device.
Remember
One editable Markdown brain that local MCP agents can read, search, and append to. Supermemory sync is optional.
A second brain should be a keystroke —
not another app to open.
How it works
Select, press, understand, remember — and the file stays yours, in plain Markdown.
Select anything
Highlight text, copy an image, or trigger it on any screen.
Press ⌃⇧2
The selection is read via the Accessibility API — globally, in any app.
Understood on-device
Vision OCRs images; a local Claude/Codex model describes them. Nothing leaves your Mac.
Saved locally
Appended to your editable second brain, available to local MCP agents, and synced to Supermemory only if you add a key.
