In Zeffy, go to Settings → Organization → API key (Beta). Tell us about your use case in a short form. Our team sends your API key back shortly after.
For ChatGPT: search "Zeffy Assistant" in the GPT Store, click "Use," and enter your API key. For Claude: add Zeffy as a connector and paste your API key. Both take under a minute.
Type a question in plain English. "Who are my top 10 donors this year?" "Which campaigns raised the most last quarter?" "Who's been giving monthly for over a year?" You'll get names, amounts, and dates back in seconds, pulled live from your Zeffy account.
You're connected. Ask anything about your donors, donations, or campaigns and get answers back in seconds, pulled live from your Zeffy account.
Your data stays in Zeffy
The connection is read-only. When you ask a question, only the answer comes back. Nothing else leaves your Zeffy account.

The Zeffy AI Assistant connects your fundraising data to ChatGPT and Claude, tools millions of people already use. No spreadsheets, no formulas, no CSV exports. Just type a question and get a specific answer.
Ask about your donors: "Who are my top donors this year?" "Who gave for the first time last month?" "Who's been giving monthly for over a year?" Ask about your campaigns: "Which campaigns raised the most last quarter?" "How much did we raise at the Spring Gala?" Ask anything you'd normally need a spreadsheet to figure out, and get names, amounts, and dates back in seconds.
The assistant pulls live data from your Zeffy account using the same secure, read-only API. No external tool can modify your Zeffy data. You can ask follow-up questions to dig deeper, just like a normal conversation.
No other nonprofit platform offers this today. Zeffy does, and it's free.
Other fundraising platforms don't offer this at any price. Zeffy's AI assistant is completely free. No subscription, no hidden costs, no per-query charges. We stay free thanks to optional tips from donors. Nonprofits keep 100% of what they raise, and there are no platform, transaction, or credit card fees, ever.
Yes, safely — with Zeffy. Most guides tell nonprofits to export a spreadsheet and paste donor info into ChatGPT, which risks leaking private data. The Zeffy AI Assistant works differently: it connects your account directly, so ChatGPT can answer questions about your donors without ever seeing your full database. Your data stays in Zeffy. Only the answer comes out.
Your data stays safe. The connection is read-only and runs over a secure, encrypted channel. No tool can modify, create, or delete anything in your Zeffy account. When you ask a question, only the data needed to answer it is pulled live from your Zeffy account.
