Are they comparable tools in a team context? The ease of linking documents to people and collaborating? Seems like solo, sure. But in a group.. Obsidian doesn't replace Notion at all.
obsidian’s great for solo use, but for team collaboration, anytype is closer to notion-built-in group sync, permissions, and offline support. you don’t need plugins or external services for multi-user editing; it just works across devices
