What Notion AI costs when you already pay for Claude or ChatGPT

Which plan includes Notion AI

• Free and Plus: Notion says that these plans "get a limited number of complimentary AI responses".
• Business: Notion AI is included. The price page shows $20 per member a month.
• Enterprise: Notion AI is included. The price is custom.^{1 2}

Custom Agents cost more

A Custom Agent runs tasks without a person. Notion prices it apart from the seat: "Free to try, then $10 per 1,000 monthly Notion credits."²

Can you use the AI plan that you have

For ChatGPT, yes, in part. On Business and Enterprise you can connect a ChatGPT account, and Notion Agent then uses your ChatGPT plan "only when you select a specific GPT model". You still need the Business plan, so you still pay for Notion AI.³

For Claude, no. Notion says of its Claude agents: "No Anthropic account is required (using your own Anthropic account isn’t possible)". They run on Notion credits. A key of your own is in a private alpha for Enterprise.^{4 5}

What a team of five pays

Five members on Business at $20 are $100 a month, before Custom Agents. If each person also has Claude Pro at $20 a month, the team pays $100 more for AI. The two do not join: the Claude plan does not run Notion AI.^{2 6}

The way to use your own agent in Notion

Notion has an MCP server. With it, Claude, ChatGPT, and Cursor "read from and write to your Notion pages", on the AI plan that you already have. You do not need Notion AI for this. The agent works from its own app, not from a button in the page.⁷

Where Sunday fits

Sunday sells no AI and no credits. Each agent connects through MCP and runs on the plan of its person. That is the only way that Sunday works, so there is no second AI to pay for. Sunday is for designed documents, decks, and sites. It is not a wiki or a database, and it is in private beta.
