SecondBrain.fyi
SecondBrain.fyi runs from your Mac menu bar, captures what you actually see on screen, stores it encrypted locally, and hands that memory to Claude, ChatGPT, Raycast, or any MCP client. OCR, browser text, accessibility trees, and on-device meeting transcripts feed a local BrainStore so you stop re-explaining context every time you switch AI apps.
Cloud memory tools log window titles and URLs. SecondBrain saves the body text behind them and serves three MCP tools: search_memory, latest_context, and active_threads. Password managers, banking screens, and incognito windows are skipped before capture. Nothing syncs to a remote server unless an app explicitly requests specific rows over MCP.
Developers and power users who live in multiple AI assistants use it as a shared memory bus. SecondBrain Pro adds unlimited history, meeting transcripts, and full-text search for $12 per month or a $120 lifetime license, with a 3-day trial and a founding lifetime offer at $84.
