Obsidian

Knowledge base with powerful AI plugins

Obsidian is a powerful local-first knowledge management and note-taking application that stores notes as plain markdown files on your device, ensuring you own your data permanently.

Researchers, writers, developers, and knowledge workers use Obsidian to build a personal knowledge graph — a "second brain" — that grows more valuable over time as connections between ideas accumulate.
