A self-hosted AI system that remembers, works in the background, and runs on hardware I own. What it does, and the design decisions behind 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.

About Pacific Slate

A self-hosted AI system that remembers, works in the background, and runs on hardware I own. What it does, and the design decisions behind it. I was in the first year of an MBA, trying to manage a firehose of information while applying to internships and keeping up with my wife and two kids, and I kept re-explaining my whole situation to whatever AI program I was using that week. I built this website to share the structure for anyone looking to do something similar.
