What is Obsidian?

The application also offers templates, daily notes, and custom CSS theming.

Obsidian is free for personal use with all core features included. Optional add-on services include Obsidian Sync at $5/month (billed monthly) for synchronizing notes across devices, and Obsidian Publish at $10/month (billed monthly) for publishing notes online. For commercial use, a Commercial license is available at $50 per user per year, while enthusiasts can support development with a one-time $25 Catalyst license that provides early access to beta versions.
User Experience
Users praise Obsidian for its flexibility and power in connecting information. The graph view feature receives particular acclaim for providing visual insight into the relationships between notes.

Bottom Line
Obsidian represents a paradigm shift in personal knowledge management, moving beyond simple note collection to creating an interconnected knowledge base. Its local-first approach ensures privacy and data ownership, while its extensibility through plugins allows for highly personalized workflows. Though it may require more initial setup than other note-taking apps, Obsidian rewards users with a powerful system for capturing, connecting, and retrieving information in a way that enhances understanding and creativity.
