Secure AIPrivate AI in n8n,
in two minutes.
Your workflows send customer names, emails, phone numbers and account numbers to OpenAI and Claude. Point your OpenAI credential at Secure AI and they are swapped for stand-ins before the model sees them, then put back in the answer. Your own model key, your own model, no workflow rebuilt.
Your workflow sends
Refund Maria Gonzalez, account 00893312,
reach her on (512) 555-0148 or

The model receives

Your workflow gets back
the reply, with Maria's real details in itEven the numbers with no label.
“Payment will be made from 10972500” never says the number is an account, so filters that look for labels send it as written. Secure AI reads the sentence, sees an account number, and swaps it out before the model sees it. The same goes for ID numbers and postcodes, while dates, prices and years stay as they are.
Set it up once.
One credential covers every workflow that uses it. Your model key is passed on to the one call that needs it and never stored.
