Sunday vs Notion
Notion is the better tool for a wiki, tasks, and databases. It has years of work behind it, and agents can read and write its pages through MCP.
Sunday is for work that must look designed: a client document, a deck, a site. A page is free-form, not a column of blocks, and you pay for no AI in Sunday.
Facts checked on . Each fact about Notion has a source.
| Notion | Sunday | |
|---|---|---|
| Which AI can edit a page | Notion AI, and outside agents through Notion MCP: Claude, ChatGPT, and Cursor "read from and write to your Notion pages".1 | Each agent that speaks MCP: Claude, ChatGPT, Claude Code, Codex, Cursor, Gemini, and others. Each person can use a different agent on the same page. |
| Price of the AI | Notion AI is on the Business and Enterprise plans. Business is $20 per member a month on the price page. Custom Agents cost $10 per 1,000 Notion credits after a free trial.2 3 | None. Sunday sells no AI and no credits. Each agent runs on the plan that you already pay for. |
| Use the AI plan that you have | In part. On Business and Enterprise you can connect a ChatGPT plan to Notion Agent. For Claude agents in Notion, Notion says that "using your own Anthropic account isn’t possible".4 5 | Yes, for each agent. That is the only way that Sunday works. |
| Shape of a page | Blocks in a column. Since 1 July 2026 an agent can make an HTML block, which Notion renders in a sandboxed iframe.6 7 | A free-form page. It has the freedom of a site, and you edit it like a doc. |
| A page as a deck | Presentation mode, in beta. Dividers make the slides. Notion states that speaker notes and shareable presentation links are not supported.8 | One page can be a document, a deck, and a site. You do not start again for a new format. |

| People on the same page | Yes. You can edit the same page at the same time with an unlimited number of people.10 | People and agents edit the same page at the same time. This applies to each type of page. |
