About
Brainstorm is a local-first knowledge-management workspace modeled as a desktop OS. An Electron shell hosts sandboxed apps — notes, databases, graph, whiteboard, calendar, browser and more — that all share one interoperable data layer built on Block Protocol, Yjs CRDTs and Lexical. Your data lives in an encrypted vault you own, syncs across devices, and stays editable offline.
