Built for GPs, solicitors, accountants, HR and others who handle confidential work. It runs on privately owned hardware, keeps nothing, and never trains on what you type, so client and patient data never becomes training data or someone else's court order. A Microsoft lawyer told the French Senate, under oath, he could not promise that. Here just for yourself? You are welcome too.

Most providers guard your data with a promise. We guard it by not having it: we process what you send, then it is gone, so there is nothing stored to leak, sell, or be compelled to hand over. And what does run, runs only on privately owned hardware, never a Big Tech API. In June 2025 a Microsoft lawyer told the French Senate, under oath, that he could not guarantee data would never be handed to US authorities. Microsoft says it has never happened; the point is they could not promise it would not. We are a UK company on privately owned hardware, with no US parent, so that question does not arise here. Read what was said.
No third-party AI sub-processors. Our AI sub-processor list is public, and it is empty. (Stripe handles payments and never sees your prompts; Cloudflare provides edge TLS and DDoS protection and is not an AI sub-processor, so no AI service other than privately owned hardware ever receives your prompts or responses.)

Every query runs on privately owned hardware. No cloud providers, no third-party AI APIs, no AI sub-processors, our list is public and it is empty. Because no one else's policy is imposed on us, we set our own: your work is processed, then wiped, and the only thing we keep is the chat history you choose to save. (Stripe processes payments and never sees your prompts; Cloudflare provides edge TLS and DDoS protection and is not an AI sub-processor.)
