Obsidian is a capable local-first knowledge base and note-taking app that stores notes as plain Markdown files, with AI features delivered through popular community plugins like Copilot for Obsidian and Smart Connections. These AI plugins enable users to chat with their entire note vault, surface semantically related notes, generate content using GPT-4, and visualise knowledge connections across thousands of linked notes. Obsidian's plugin platform makes it one of the most extensible and customisable AI-improved knowledge management tools available.

Best for: Power users and researchers who want maximum customisation and AI capability over a large personal knowledge base.
