Projects
shotsync
Your own cross-device image and text pool, self-hosted on Cloudflare's free tier. Drop a screenshot on one device, pick it up on another — hours later, on a different network, with the first device asleep. Live demo, no install.
day-monitor
macOS menu-bar app that answers what you were doing, not which app was open. Two hours in an editor comes back as "wrote a React component", "chased an API error" — activity-level, comparable across apps, written up as a daily report. Runs locally.
screen-coach
macOS English reading coach. Frame any region of your screen and get a translation, a clause-by-clause breakdown, and usage notes in a floating window — for people who know the words but not the sentence.
