Plate 01 / 03 · Sidenote's three-pane notes layout: notebooks, note list and editor, with a note open.
Sidenote is a private notes and knowledge base that runs in your browser. Every note lives in IndexedDB, the app opens offline, and sync is optional against a Supabase you control. Free and open source under AGPL-3.0.
Nested notebooks, a note list and the editor. On a phone it collapses to one pane with back navigation; the sidebar can shrink to an icon rail.
Every note lives in your browser's IndexedDB. The app opens offline, with no account and no server, and asks for eviction protection where the browser allows it.
Set two Supabase variables to add sign-in, cross-device sync and share links. Without them every remote path is a no-op and nothing leaves the machine.
[[Note Title]] links and a backlinks panel, stored as plain text. Export Markdown, standalone HTML or a ZIP backup; import a ZIP or an Evernote .enex file.
