One App. Any Structure. Yours, Offline.
A local-first knowledge base on HTML5 + SQLite — zero dependencies, pure speed. Pick who you are and watch the workspace become yours.
Most tools make you fit their template. CacheYourBrain gives you a fast, private database that fits you — whatever shape your knowledge takes.
Offline-first, always
Your data lives in a SQLite database on your machine. No cloud, no account, no tracking — works on a plane, still works if we disappear.
Any structure
Hierarchies as deep and as odd as your subject demands — modelled your way, not a template's way.
Zero dependencies
Native HTML5 and SQLite WASM. No frameworks, no bloat, no supply chain. Instant startup, instant search.
Portable & shareable
Import and export whole databases. Grab a community starter, make it yours, share your structure back.
