Story arc

How this shipped

End-to-end solutions from database to deploymentThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Knowledge tools force a choice: offline-first (Obsidian) OR collaboration (Notion). CRDTs enable both but are complex to implement correctly.

II · Build

The craft

Built on Yjs CRDTs for conflict-free real-time sync that works offline. BlockNote + Tiptap editor provides Notion-like blocks. Native AI integration for intelligent queries. Supertags enable flexible organization.

III · Proof

What moved after launch

True offline-first with seamless sync. Real-time collaboration without conflict resolution headaches. Cinematic Dark Mode with snappy motion UI.
