ChatGPT is the more powerful product. It is also a US company.
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.

Rows describe what each company keeps about you from public terms and filings reviewed July 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.

What ChatGPT does better than us
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.
The one structural difference
OpenAI is a US company, and ChatGPT runs on Big Tech 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 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 AI privacy checker asks seven questions, keeps no answers on our servers, 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 hardware we own, not a Big Tech cloud, 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.
Frequently asked questions
Is ChatGPT (OpenAI) in the habit of keeping a copy of what you type?
OpenAI is a US-incorporated company and ChatGPT runs on Big Tech cloud infrastructure. The US CLOUD Act applies to US providers wherever the data is stored, so selecting a UK or EU data region does not remove the jurisdiction question; it belongs in your DPIA for any confidential UK data.
Does ChatGPT train on my conversations?
It depends on the tier. OpenAI's free and Plus tiers may use conversations to improve models unless you opt out; Team, Enterprise and the API do not train on your content by default. Check the tier you are on. Hush never trains on your content, on any plan. For the exact terms, run our AI training checker.
What is a private alternative to ChatGPT?
Hush AI is a private alternative that runs on hardware it owns, outside US CLOUD Act jurisdiction, never trains on your content, and gives a one-click audit-log export. For raw general capability ChatGPT is class-leading; Hush's advantage is jurisdiction, governance tooling and drafting-under-review for regulated work.
