Obsidian is a local-first Markdown knowledge base — link notes, visualize a graph, and extend everything with plugins. This Obsidian review updates July 2026 versus Notion for teams and Microsoft 365 for documents.
What Is Obsidian?
A free personal knowledge management (PKM) app that stores notes as plain Markdown folders on your device. Optional Obsidian Sync encrypts across devices; Publish shares selected vaults as websites.

Linking, Graph, and Daily Notes
Bidirectional links and unlinked mentions turn writing into a network. Graph view helps discover forgotten connections. Daily notes and templates support journaling, research, and Zettelkasten-style workflows popular with students and writers.
Plugins, Themes, and Pricing
Community plugins add kanban, calendars, AI assistants, and spaced repetition — power users build custom IDEs for thought. Core personal use stays free. Sync and Publish subscriptions fund the company without locking your files behind a proprietary format.
