Obsidian

★ 4/5 · Business Productivity

Obsidian is a local-first knowledge base and note app beloved for linked thinking and plugins.

Pros

• Free forever core app with unlimited vaults
• powerful linked thinking and graph view
• extensive plugin ecosystem
• strong local privacy (end-to-end encryption for Sync)

Cons

• Sync and Publish are separate paid add-ons
• steep learning curve for advanced features
• limited built-in collaboration (requires third-party workarounds)

Cost

Free (core app); Sync $48/year or $60/year; Publish $120/year or $96/year annual billing; optional Catalyst $25 one-time; commercial license $50/year

Verdict

Best for knowledge workers and researchers who prioritize privacy and networked note-taking, and don't mind managing a personal knowledge system.
