Hi, I'm Henry.

I build and ship local-first AI tools solo, on one idea: you should own the model of yourself, and it should show its work rather than guess.

Right now that is Footnote, a personal AI memory you own, with a citation for every claim; Study Surfers, an LLM study app on iOS with 2,250+ downloads; and Agenteria, a menu bar app for Claude Code sessions.

Most of it is open source, and all of it is checkable. More about me, or find me on GitHub.
