Custom connector · MCP
Connect Notebook once, and your assistant can build real HTML documents from your sketches — dashboards, reports, decks, flow boards — with your data, your logo, and full version history.
Takes about two minutes · Works with Claude and ChatGPT
Sketch it
Draw the layout on the Notebook canvas, or just type what you want.
→Send it
One tap sends your prompt, pages and files to your assistant.
→It builds
Claude or ChatGPT writes the document and saves it straight to your project.
→Use it
Edit on the canvas, share a link, export a PDF. Every version kept.
Three ways in: the Claude connector, the ChatGPT connector (needs Developer Mode), or a Custom GPT with your Notebook API key — the Custom GPT route works on ChatGPT Plus.
Free to start. You'll need it so the connector has somewhere to save your work.
In the Claude app or claude.ai, go to:
Leave the optional OAuth fields empty — Claude fills those in itself.
Notebook shows a “Connect to Notebook?” page with your account name. Click Approve and you're done.
Claude lists your projects, helps you pick one, and gives you a direct link. From there, ask it to build anything.
Free to start. The connector saves everything it builds into your Notebook projects.
Custom connectors live behind Developer Mode. In ChatGPT:
On Business, Enterprise or Edu, a workspace owner enables it under Settings › Connectors — look for “Connected data / Developer mode”.
Choose Create (or “Add custom connector”), name it Notebook, and paste this MCP server URL:
Set authentication to OAuth and leave client details blank — ChatGPT registers itself automatically.
Notebook shows a “Connect to Notebook?” page with your account name. Click Approve.
ChatGPT asks you to turn connectors on per conversation — open the tools menu in the composer and switch Notebook on. Then say “open Notebook”.
The API key that authenticates your GPT is generated inside Notebook — there's no key without an account. Free to start.
Sign in, open any project, and click the plug icon in the toolbar:
You can generate a fresh key from the same place at any time — the old one stops working the moment you do.
In ChatGPT: Explore GPTs › Create, open the Configure tab, then Create new action › Import from URL and paste:
Six actions appear: getCanvasRequest, submitBuild, sendResponse, readArtifact, listProjects, createProject.
Click the gear next to Authentication and choose:
Drop this into the GPT's Instructions field so it knows the Notebook workflow:
In Notebook's co-pilot, attach a sketch or pages, switch the route-to-ChatGPT toggle on, and hit Send. Then tell your GPT “go” — it picks the request up, images arriving as rich text interpretations.
Notebook does the parts a chat window can't: a real canvas, real files, and documents that keep their history.
Draw a layout on the canvas, hit Send, and get back a working HTML dashboard or report built to your sketch.
Attach a CSV or spreadsheet and the artifact queries the actual rows — no invented numbers.
Upload a logo and it's embedded as the real file, never redrawn or approximated.
Every build and edit is a version you can compare, restore, or roll back — from either side.
Publish a share link, download a self-contained HTML file, or export a clean PDF.
Switch Build off and your assistant answers questions or returns files right in the Notebook chat.
Yes — the connector saves work into your projects, so it needs an account to link to. If you start from Claude or ChatGPT without one, the approval page will point you to sign-up; you can create the account there and then approve. Signing up is free and takes an email address.
You can add the connector in both, but only one drives a Notebook at a time. Choose which in Notebook's side panel under Settings › Connect to Claude / Connect to ChatGPT. The Send button in the co-pilot follows whichever is switched on.
Your assistant writes the documents, so that work runs on your Claude or ChatGPT plan. Notebook credits are only used if you ask Notebook's own builder to do the work instead.
Assistants can only listen for a few minutes per turn. When it goes quiet, work in Notebook, press Send, then type go in the chat — it picks up whatever is waiting.
No. The connection is scoped to your account: your assistant sees only the projects and files in your Notebook, and you can revoke access at any time from Notebook's settings.
Create a free Notebook, connect your assistant, and turn your next rough idea into a real document.
