Notion is an all-in-one workspace that combines documents, wikis, databases, project management, and AI tools into a single interface. Teams use it to write, plan, and organize work without jumping between apps. It started as a flexible note-taking and knowledge-base tool but has expanded to include meeting notes, calendar, search, and now AI agents that can automate multi-step workflows. The product is sold via tiered SaaS subscriptions — Plus, Business, and Enterprise — with AI features (writing assist, enterprise search, meeting summaries, custom agents) bundled into the higher tiers. Buyers range from individual freelancers to Fortune 500 enterprises. The core GTM motion is product-led growth: users adopt Notion for free, then teams expand and upgrade. Notion is now repositioning itself as an AI orchestration layer — a place where human teams and AI agents collaborate on the same knowledge graph.
