Octo is a web-based note-taking and knowledge management application ('second brain') that syncs privately across devices using client-side end-to-end encryption. It works offline via Service Workers and IndexedDB, and offers import/export tools to avoid vendor lock-in. The team emphasizes transparency by making the source code freely available.
