Obsidian is a markdown-based note-taking app that stores files locally. Smart Connections uses AI to surface related notes and generate insights without sending data to external servers.

Obsidian provides a graph-based knowledge management system where notes link together visually. Smart Connections, a community plugin, adds semantic search and automated note discovery by embedding your content locally. Unlike cloud competitors, all processing happens on your device—your data never touches external AI services. Supports backlinks, bidirectional linking, and customizable workflows through plugins.

Cons
