Notion is an all-in-one workspace that combines notes, documents, wikis, databases, project management, and AI into a single platform. Its AI layer extends across the entire workspace, providing writing assistance, summarization, translation, Q&A over your content, and the ability to build and orchestrate custom AI agents.

Notion AI includes features like inline writing assistance (draft, edit, summarize, translate), automatic meeting notes from recordings, knowledge-base Q&A that searches across all connected content, and custom AI agents that can be configured for specific workflows. The platform integrates with hundreds of external tools via API and has a rich template ecosystem.

Notion is used by individuals for personal knowledge management and by teams of all sizes for company wikis, project tracking, CRM, product documentation, and more. It supports real-time collaboration, Markdown and block-based editing, relational databases, calendar views, and automations through buttons and formulas.
