About Brainstorm

Brainstorm is a local-first, AI-native operating system for knowledge management. Your apps, your data, and your AI all run on your machine, with optional end-to-end encrypted sync, and every app and every agent only touches what you allow. Nothing is kept until you choose, and you can change your mind whenever you like. Brainstorm is free and open source, if it's useful to you, star it on GitLab. Install what you need, keep every file on your disk, and let AI help, only with the parts you hand it.

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.
