Dani Postma
I build local-first AI tools. Hundreds of builds in a year, most of them private — the loudest one is EVOLV, a workspace that rewrites its own interface while it runs.
Currently building EVOLV with Aaron Wise.

EVOLV
A self-evolving AI workspace: one Go binary that thinks, writes real components into its own source tree, and pushes them over WebSocket so the interface changes while you watch. No refresh, no rebuild, no restart.
It started as a question — what if the app could rewrite itself while you watched? — and became the biggest thing I've shipped: local-first, no signup, works with Ollama or any API key, and it keeps an append-only ledger of every change it makes to itself.
