Your AI tools, working from the project.

Anything that speaks MCP. In practice that is Claude, ChatGPT, Cursor and Codex. Each connects to the same projects, so it does not matter which one you open. What that looks like across a working day is in how to share context between ChatGPT, Claude and Cursor.

• Read a project. Its spaces, its assets and their statuses, and the facts the project treats as current.
• Search it by meaning, and open any single asset in full rather than working from an excerpt.
• Save what it writes (notes, scripts, prompts, briefs, images) into the project and the space you name, as drafts, marked with what they were made from.
• Revise what it wrote. The previous version is kept in that asset’s history, so nothing is lost by letting it edit.
• Create a project or a space when the work needs one, so a conversation can be filed without leaving the conversation.
• Record what the project settles. A fact the project did not know yet, such as a launch date you just agreed, is recorded straight away. One that contradicts a fact already in force is filed as a suggestion instead, and waits for you.

It cannot overrule what the project already treats as true: a contradiction waits for you in Review, and the value in force stays in force until you decide. It cannot delete anything either; if something should go, it says which one and you remove it. And it holds no access of its own. It acts for you, with the same reach you have, until you disconnect it in Settings → Connections, which ends it immediately.

Settings → Connections in Seylo shows one address. Paste it into the tool’s connector settings, and Seylo opens in your browser to ask you to sign in and approve the tool, once. The tool then keeps a connection that renews itself; nothing else is copied. The steps for Claude, ChatGPT and Cursor, with what to do if the tool cannot see your projects afterwards, are in the help centre: connect Claude, ChatGPT or Cursor through MCP.

A tool that cannot open a browser can use a token instead, made on the same screen. A token acts as you, so it belongs in the tool’s own configuration and nowhere else. If one ever ends up somewhere it should not, revoke it from the same screen.

Connecting an assistant is part of Pro, at $5.99 per month, billed annually. The free plan keeps three projects, the browser extension and search, and everything you save there stays yours to export. The full comparison is on the pricing page.
