# Notion Notion is an all-in-one workspace combining notes, wikis, databases, and project management. Founded in 2013 by Ivan Zhao and Simon Last, it gained popularity for its flexible block-based editor and powerful database features. Notion is often used for team documentation, knowledge bases, and collaborative workspaces. While powerful for collaboration, Notion has limitations for [[Personal Knowledge Management (PKM)]] compared to tools like [[Obsidian]]: slower performance with large vaults, data stored in the cloud (not local), and less emphasis on bidirectional linking. ## Key Features - **Block-based editor**: Everything is a draggable, nestable block - **Databases**: Tables, boards, calendars, galleries with relations and rollups - **Templates**: Reusable page structures - **[[Wiki]]**: Team documentation with nested pages - **Collaboration**: Real-time editing, comments, mentions - **API**: Integrations and automations - **AI features**: Writing assistance, summarization ## Use Cases - Team documentation and wikis - Project management (Kanban boards, roadmaps) - Collaborative editing and knowledge bases - Publishing websites (Notion Sites) - Personal dashboards and databases - CRM and inventory tracking ## Notion vs Obsidian | Aspect | Notion | [[Obsidian]] | |--------|--------|----------| | Data storage | Cloud | Local files | | Format | Proprietary | Markdown | | Collaboration | Built-in | Limited | | Performance | Slower | Fast | | Offline | Limited | Full | | Linking | Basic | Powerful graph | ## References - https://notion.so - https://en.wikipedia.org/wiki/Notion_(productivity_software) ## Related - [[Obsidian]] - [[Personal Knowledge Management (PKM)]] - [[Wiki]] - [[Knowledge Management (KM)]] - [[Notion CLI]]
