What a workspace for people and AI agents is

Why this is possible now

MCP gives each agent one way to connect to a tool. Claude adds a custom connector on each plan. ChatGPT adds a custom MCP server on its Business, Enterprise, and Edu plans. Codex, Cursor, and the Gemini CLI add one with a command or a file.^{1 2 3 4 5}

The tools answer in kind. Notion, Gamma, and Google Workspace each have an MCP server.^{6 7 8}

Four tests

1. Each agent can write. The agent of one person is Claude, and the agent of the next is ChatGPT. Both edit the page.
2. A person can change each part by hand. No part of a page needs a prompt.
3. People and agents work on the same page at the same time.
4. The work has a home: folders, links, versions, and limits on what an agent can open.

What it is not

• A chat with a canvas. The page belongs to one AI, and other agents cannot open it.
• A document tool with an AI inside. You pay for that AI, and it is the first-class agent.
• A host for HTML files. It gives a link, but no editor and no second author.

How the products of 2026 do

• Claude artifacts: people edit a template doc by hand and together. A designed page changes by prompt. The agent is Claude.
• ChatGPT Space and Sites: people edit a Space page by hand and together. A Site changes by prompt. The agents are ChatGPT and Codex.
• Notion: outside agents write through MCP, and people edit together. The page is a column of blocks, and an HTML block has no editor.
• Gamma: outside agents write through MCP, and people edit together. The page is a set of cards.
• Sunday: made for the four tests, with a free-form page. It is in private beta.^{9 10 11 12 6 13 7 14}

Questions to ask before you choose

• Which agents can edit a page, and on whose plan do they run?
• Can I change a designed page by hand, or only by prompt?
• Can I limit an agent to one page?
• What happens to a page when an agent makes a bad change?
• Can a person with no account open a link?
