In their own words
Obsidian
Obsidian is a note-taking app for keeping notes and building a personal knowledge workspace. Its core app is free, has no sign-up requirement, and stores notes on the user's device so they remain available offline. It runs on Windows, macOS, Linux, iOS, Android, and as a Chrome extension. Canvas provides an open workspace for research, brainstorming, diagrams, and ideas; thousands of plugins and an open API allow workflow customization. Shared vaults support team work with real-time updates. Sync adds synchronization and version history: Standard costs $5 per user per month billed annually, with one vault, 1 GB of storage, a 5 MB maximum file size, and one month of history. Plus costs $10 per user per month billed annually, with 10 vaults, 10 GB, a 200 MB maximum file size, and 12 months of history. Publish is $10 per site per month billed annually and includes up to 4 GB hosting per site. It offers themes, custom domains, password protection, and SEO optimization.
