Become a sponsor to Vincent Jacobs
AIrail
A barely-there hairline on the edge of your Mac's screen that fills and warms as your nearest AI limit does — Claude Code, Codex, Cursor, Copilot and API keys — with a glass card behind it for the details.
It's free and MIT. It reads only the sign-ins your tools already keep, never writes anything back, and talks to seven allowlisted hosts and nothing else. Settings › Privacy lists every one of them.
What sponsorship pays for. The first $99 is the Apple Developer Program: notarized builds that macOS opens without the "can't check for malware" warning, and in-place updates. After that, it's the time to keep the parsers honest as the tools change their billing under everyone.
What it never changes. Everything already shipped stays free, and privacy features are never paid.
