If you want the strongest general-purpose model for work you would be comfortable seeing on a billboard, buy ChatGPT. If you handle patient, client or employee data under a UK regulator, there is one fact about ChatGPT that belongs in your records — and it is not about quality.
| Hush AI | ChatGPT (OpenAI) | |
|---|---|---|
| Company ownership | UK company | US company (OpenAI) |
| Where inference runs | Hardware we own, in England | US-owned cloud (Microsoft Azure) |
| US CLOUD Act jurisdiction | Outside it | Within it |
| Audit-log export for your IG lead | ✓ one click, all plans | Enterprise tiers |
| Content used to train models | Never | Opt-out; on by default for free/Plus |
| Frontier model capability | Strong for drafting tasks | Class-leading |
| App / plugin ecosystem, voice, free tier | No | Yes |
Rows describe company ownership and jurisdiction from public terms and filings as of June 2026. OpenAI is a US-incorporated company; the CLOUD Act (H.R.4943, 2018) applies to US providers wherever data is stored. Training behaviour differs by tier — ChatGPT's free and Plus tiers may use conversations to improve models unless you opt out; Team, Enterprise and API do not train by default. Check the tier you are on. Spot an error? Tell us and we will correct it within one working day.
Frontier-class reasoning, the largest ecosystem of apps and integrations, image generation, voice mode, and a genuinely useful free tier. For brainstorming, coding, learning and any work that is not confidential, it is an outstanding tool and we are not going to pretend otherwise.
OpenAI is a US company, and ChatGPT runs on US-owned cloud infrastructure. Under the US CLOUD Act, a US provider can be compelled to disclose data in its possession regardless of where that data is stored. Choosing a "UK" or "Europe" data setting changes the geography, not the jurisdiction.
For a regulated UK professional, that means your DPIA for ChatGPT cannot truthfully say "no third-country authority could be compelled to access this data." You may still decide the residual risk is acceptable for non-sensitive work — but the assessment has to be honest. A Microsoft executive conceded exactly this point to the French Senate, under oath; the same logic applies to every US-owned provider.
Want to see where your current setup lands? The two-minute CLOUD Act exposure checker asks seven questions, stores nothing, and gives you a result you can forward to your DPO.
Choose ChatGPT if your priority is raw capability and breadth on work that is not confidential, and your information-governance lead has signed off the jurisdiction question for any sensitive data you put through it.
Choose Hush if you routinely draft documents containing patient, client or employee information and you need to be able to write, truthfully, that the tool sits on UK-owned hardware outside US jurisdiction, with an audit trail you own. Hush drafts under your review — it is not a frontier-capability competitor, and it is not an ambient scribe.
