Assistant

The assistant is the first thing you see in nullish. There's no dashboard full of charts: if you want to know something, ask.

• "Which invoices are still open?"
• "What's left on the bank account?"
• "How much VAT do we owe for this year?"

Your conversations are kept under History, and New starts a fresh one.

Read only or read and edit

By default the assistant is Read only: it looks things up but changes nothing. Click the label to switch to Read and edit when you want it to create or update things for you, and click again to set it back.

Note

The assistant can never do more than you can. If your role is reviewer, it stays read only.

Connect your own AI agent

Prefer your own AI, like Claude or ChatGPT? Connect it to nullish over MCP and do your bookkeeping from there.

1. Open the menu with your name and go to API keys, then choose Create API key.

2. Give it a Name, pick an Expiration, and choose MCP server as the Resource.

3. Pick the Access: Read to let your agent look things up, Read and write to let it create and update things too.

4. Copy the key. It isn't shown again.

5. In your AI agent, add nullish as an MCP server with this key. The MCP page shows how.

Your agent works with your own access, across all your organizations, and the same limits apply as in the app. Delete the key and it loses access immediately.
