About HeimWall

Signal, not surveillance. See how your engineers use Cursor, Claude Code, and Copilot: catch leaked secrets, PII, and confidential data, without blocking them or reading their prompts. Nothing sits in your send path, your prompt reaches the tool untouched, and what you type into an AI tool is never sent to us. To read your prompt before it is sent, the app reads the composer through the macOS Accessibility API and watches the clipboard. Accessibility is a wide permission and macOS does not offer a narrower one for this.

About MetaBrain

metaBrain is open-source local document memory for AI tools, coding agents, and humans, with searchable notes, metadata, tags, links, version history, and an optional local daemon. Give every agent one durable, searchable place for notes, source snippets, task context, metadata, tags, links, and version history. The quickest path is the `mb` CLI: initialize a local store, write a note, search it, and keep moving. The optional server is there later when several tools need concurrent access.
