Agentic Inbox |
- Agentic Inbox: an AI agent sorts a shared inbox; sensitive mail always waits for a human, and every action can be reviewed and undone.
- Pully: a native Android app for reviewing pull requests, with two panes on foldables. Design book
- Inventory: a private library for everything you save, where every save feels like loot. An Android app on a Rust server on Cloudflare Workers. Design book
- octaviantocan.com: my site and its interactive details. Design book
Design books
I keep one Figma file per product, in the same format: foundations, every component and its states, full-screen examples, and the decisions behind them. See them all, including the design system I built at Ojin.
Also building Pawrrtal, my own AI agent workspace.
