Obsidian is a local-first knowledge base built on plain markdown files stored on your machine. Its bidirectional linking and graph view let you see how ideas connect, turning scattered notes into a living knowledge network. With 1,500+ community plugins — from kanban boards to database queries to automated templates — it bends to fit any workflow. Unlike Notion or Google Docs, your data never leaves your device unless you choose to sync it, and there is zero vendor lock-in because every note is just a .md file.
Key features

How we use it
Our entire vault system is Obsidian — it is the knowledge graph, CRM, planning hub, and operational memory for the business. Atlas files drive daily priorities, people files track relationships, playbook files codify strategy. Claude Code reads and writes directly to the vault, making Obsidian the bridge between human thinking and AI execution.
