Notion AIvsObsidian
Notion and Obsidian represent opposite philosophies in knowledge management. Notion is cloud-based, collaborative, and all-in-one — combining notes, databases, wikis, and project management. Obsidian is local-first, privacy-focused, and built for individuals who want to own their data as plain markdown files. Both are excellent; the right choice depends on whether you prioritize collaboration and polish or control and privacy.
