Notion

Notion is an AI-integrated workspace for teams and individuals who need a single place for docs, wikis, projects, and knowledge management.

Key AI capabilities include:

• Custom Agents (Notion Agent) that can autonomously complete tasks such as creating and editing pages, databases, and charts using workspace context.
• Enterprise Search with AI connectors to query knowledge across Notion plus connected tools like Slack and Google Drive (Docs, Sheets, Slides).
• Writing and editing assistance for generating, rewriting, translating, structuring essays, and brainstorming within documents.
• Database AI Autofill to generate summaries, keywords, and other fields from custom prompts.

Pricing: Freemium; Notion AI is an add-on that requires Business or Enterprise plans for workspace-wide access.

What makes it notable: It combines agentic task execution, cross-app search, and workspace-aware AI in the same system used for documentation and project tracking, and it supports integrations via API and tools like Zapier. Available on Web, Desktop, iOS, and Android.
