Notion AI
Excellent AI glue if your work already lives in Notion — outside the workspace it reads far better than it writes, and the credits meter is the price of the agent dream.
Element scores
Strengths
Context is the moat: Q&A, Enterprise Search and agents grounded in the workspace you already maintain, with connectors into Slack, Drive, GitHub, Jira and Linear. The multi-model picker (GPT-5.x, Claude Opus, Gemini) is unusually open for a workspace tool, AI Meeting Notes is best-in-class, and the hosted MCP server plus the May 2026 Developer Platform (Workers, External Agent API) turned Notion into a genuine agent hub. Business at $20/seat including full AI undercuts stacking separate AI subscriptions.
Honest dings
Full AI requires the Business plan — Free/Plus get a one-time trial widely described as a trap, and solo users lost the $10 add-on in May 2025. Custom Agents meter at $10/1,000 credits on top of seats, with fair-use throttling that isn't clearly published. Q&A reliability degrades in deep or messy workspaces, agents read external tools far better than they write to them, there's no eval surface at all, and first-draft writing quality trails Claude/ChatGPT.
