Brainstorm
Brainstorm is a desktop operating system designed for knowledge management that runs entirely on the user's machine. It features a real desktop environment with sandboxed apps for notes, databases, files, graphs, calendars, and code editing, all operating on a single local data store. AI assistance is available but only accesses data the user explicitly allows, with optional end-to-end encrypted synchronization. The system is free and open source, emphasizing user control, privacy, and composable applications over traditional cloud-based note-taking tools.
