Product Architecture

Productivity docked right where you work.

Modern workflows demand frictionless note-taking. Switching between browser tabs to open dedicated note apps creates cognitive friction and interrupts flow. Keep Sidebar docks comfortably in Chrome's native 320–480px side panel, remaining accessible across all websites.

Engineered with an offline-first philosophy, notes are immediately written to local browser IndexedDB. Edits never lag on slow networks, and users who prefer complete privacy can use the Extension without logging in or sending a single byte across the internet.
