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 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.

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
It is not where your data sits. It is whether there is any data to take. ChatGPT keeps your conversations, and because OpenAI is a US company, the US CLOUD Act can compel disclosure of what it holds no matter where it is stored, so a "UK" or "Europe" region setting changes the geography, not the reach.
Hush keeps nothing you type. Your prompts and answers are processed on privately owned hardware and then gone, with no transcript kept on our side for anyone, in any country, to compel, subpoena, or leak. There is nothing to hand over, because there is nothing kept.
For a regulated UK professional, that is the difference between a DPIA that has to weigh third-country access and one that can say, plainly, that there is no retained content to access. A Microsoft executive conceded the jurisdiction point to the French Senate, under oath; Hush sidesteps it by keeping nothing.

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 privately owned hardware, 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.
What is a private alternative to ChatGPT?
Hush AI is a UK-owned alternative that runs on privately owned hardware, 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.
