What to expect from an ideal product

1. Koru syncs your notes directly between devices without a central server, so your data never touches a cloud you don't control.
2. End-to-end encryption is built into the sync layer, meaning even if someone intercepts the connection, they read nothing.
3. Because Koru is built natively in Rust, it opens instantly and runs lean on Windows, macOS and Linux without the memory bloat of Electron apps.
4. Your AI agents connect to Koru over MCP and can read, create or edit notes and files directly, no copy-pasting content into a chat window.
5. Koru works fully offline, so your notes, tasks and documents stay accessible whether you are on a plane, in a basement or on a spotty connection.
