Before connecting, review financial data privacy and security: where your token is stored, what your AI receives, and how to stop access.

Step 1

Sign in

After installing, sign in when asked. The sign-in at auth.n3wth.com is for this plugin, separate from your Lunch Money login.

Step 2

Link Lunch Money

Ask your AI to connect Lunch Money, then open the link it gives you.

Step 3

Add your API token

Request a new access token in Lunch Money, then paste it into the connection page. Never paste it in chat.

Step 4

Start a conversation

Once connected, try asking something like “How much did I spend this month?”

Stay in control.

Nothing gets changed

Your AI can read your finances, but can’t change records or move money.

Your AI receives records

Retrieved records are sent to your AI app. How it stores and uses them depends on your AI provider’s policies and settings.

No financial history stored

This connection looks up your records when you ask. It doesn’t keep a copy of the financial details it returns.

You can stop access

Revoke your token in Lunch Money to stop access. Ask your AI to disconnect to delete the saved connection.
