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.

AI output seldom meets the intent on the first prompt, so iteration is necessary. Today, iteration usually means providing feedback in a follow-up prompt, which leads to a rewrite of the whole document.

That is absurd, this workflow has been solved for decades by comments and tracked changes in Word, or by Suggesting mode in Google Docs. Let's play through the process of creating a document, and iterate once.
