Notion AI

Freemium

4.0

Notion's native AI layer that operates across your entire workspace — pages, databases, projects, and meeting notes. Updated in 2025 with full workspace Q&A (ask questions across all your notes), automatic action item extraction from meetings, and smarter database queries using natural language. Available as an add-on to any Notion plan at $10/user/month.

Category:Productivity

Features

Workspace Q&A: ask questions across all pages, databases, and team wikis
Action item extraction from meeting notes with automatic assignee detection
AI database queries: filter, sort, and analyze data with natural language
AI writing assistant with context-awareness across the current page
Autofill database properties using AI from page content
+3 more

Pros

Workspace Q&A replaces manual search for teams with large wikis — answers come with source citations
Action item extraction from meeting transcripts saves 10-20 minutes per meeting of manual note cleanup
Database autofill allows structured data entry at writing speed — describe a project and properties populate automatically
Native integration means no data leaves Notion to a third-party service for AI processing

Cons

Costs $10/user/month on top of the Notion plan ($8-18/user/mo) — total cost is $18-28/user/mo for AI-enabled teams
Workspace Q&A quality drops when pages are poorly formatted or lack structure — garbage in, garbage out
AI writing suggestions are less capable than dedicated writing tools (Claude, ChatGPT) for complex creative work
Database queries via natural language still fail on multi-join queries and complex aggregations
Action item extraction requires clean meeting transcripts — works poorly with speaker-unattributed raw notes
