I build small, private Mac apps. The AI runs on your machine and your data stays there.

Apps

  • Tilde — a Mac keyboard that finishes your sentences. Works in every app. Nothing you type leaves your Mac.
  • Transcripted — record meetings and dictation. Everything becomes plain Markdown files you own.

Tools for building with AI

  • Antibody — flag a failure once, catch it forever. File-native evals for AI failures.
  • Nightshift — overnight repo scans, ranked into a morning brief. Drafts, not deploys.
  • BetterFeedback — a self-hosted "Give feedback" button with voice and screen capture.
