“Is It Safe to Use with My Customer Data?”
This is always the first question. Always.
In a recent workshop, a director of an estate agency with hundreds of thousands of customer records put it bluntly: he wanted to understand AI, he could see the potential, but the idea of feeding client data into a system he did not fully understand made him deeply uncomfortable.
He is right to be cautious. And the answer is more nuanced than most AI enthusiasts care to admit.
The short version: consumer AI accounts (the free versions most people start with) offer limited privacy guarantees. You often cannot control whether your data is used for training. Business and enterprise accounts from the major providers — Anthropic, OpenAI, Google — contractually commit to not training on your data, encrypting it, and not allowing human access.
But “contractually commit” is not the same as “guarantee.” The only true guarantee is running AI models locally on your own hardware, which is becoming more feasible but still requires significant investment.
The first wins come from internal documents, reporting, email drafting, and strategic planning. None of that requires customer records.
