Use Nitti in Claude or ChatGPT.

Before you start

You need a Nitti account that belongs to an organisation. You will also need this connector address:

You sign in with your Nitti account when you connect. You do not need an API key.

Claude (web, desktop, and mobile)

1. On claude.ai or in the Claude desktop app, open Customize → Connectors, click +, and choose Add custom connector.
2. Name it Nitti, paste the connector address, keep Requires sign-in on, and leave the optional client ID and secret fields blank. Click Add.
3. Click Connect, sign in to Nitti, and approve access.

You only add it once. Nitti then works in Claude on the web, in the desktop app, and in the mobile app.

On Team and Enterprise plans, an owner adds Nitti first under Organization settings → Connectors. Members then click Connect under Customize → Connectors. See Anthropic's custom connector guide.

Claude controls these approval settings; Nitti cannot change your saved choices. Ask pauses for approval before a tool runs, while Always usually skips that per-use prompt. Work accounts may restrict these choices.

To stop prompts for Read skill, open Customize → Connectors → Nitti and set it to Always. Set any other tools you trust to Always individually; switch a tool back to Ask to approve each use.

Read skill only loads Nitti's task instructions; it does not search your Nitti content or make changes. These Claude settings only control prompts; they do not change the access granted by your signed-in Nitti connection.

Claude Code

If you already added Nitti in Claude and sign in to Claude Code with the same Claude account, it is already there. Otherwise, run this in your terminal:

Then start Claude Code, type /mcp, choose nitti, and sign in to Nitti.

ChatGPT

Nitti is not in the ChatGPT app directory yet. Until it is, add it with developer mode on chatgpt.com. This needs a Plus, Pro, Business, Enterprise, or Edu plan.

1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
2. Go to Plugins and click +.
3. Name it Nitti, paste the connector address, and choose OAuth if asked.
4. Sign in to Nitti and approve access.
5. In a chat, turn Nitti on from the Developer mode tool in the message box.

Developer mode only works on chatgpt.com, not in the ChatGPT desktop or mobile apps. Use Nitti in your browser until it is in the app directory. See OpenAI's developer mode guide.

Other assistants

Any assistant that supports remote MCP connectors can use the same connector address.

What it can do

Your assistant can search and read data from the Nitti organisation you connect. With extra access to make changes, it can create projects, folders, and notes, revise existing notes, and manage research. Claude cannot edit source material or delete existing projects, folders, or notes.

Claude must show you the research cost estimate and get your approval before a research run starts.

Notes and charts

In Claude and ChatGPT, charts and notes can appear as cards in the chat. Click Expand on a chart or Open note on a note to see more. Hosts that support full screen open the card there; other hosts expand it in the conversation.

Share asks you to confirm before creating a public link. Anyone with the link can read the note, including short excerpts from private sources if you consent. Full source documents stay private. Edit in Nitti opens the saved note; sign in with an account that has access to it. Notes belong to the Nitti account that authorised the connector.

Creating or revising a note requires write access. Your assistant controls any additional prompts before tools run.

If a card looks old or does not load, refresh the Nitti connector's tools and start a new conversation. Your assistant may still cache an older card. If the problem continues, reconnect Nitti or open the saved note with Edit in Nitti.

Disconnecting

Remove the connector in your assistant's settings. This does not cancel access that was already granted: an access token issued before then stays valid until it expires, which can take up to 24 hours.

To cut off someone's access, remove them from the organisation in Nitti. Nitti denies their access from that point on.
