Hush AI vs ChatGPT, Copilot and Gemini
They are excellent products made by the best-funded AI companies on earth, and for many tasks they will be faster and smarter than us. This page is about the dimensions where we are structurally different: we keep no conversations or documents, we process what you send, then it is gone, so there is no conversation or document to leak or be compelled to hand over, and the machines that do the processing are owned by us, with no US parent, beyond the reach of foreign courts. We also say plainly what each product does better than we do.

Competitor rows describe what each company keeps about you, based on public terms and filings, reviewed July 2026. On their consumer tiers ChatGPT, Copilot and Gemini keep a copy of what you type by default and may use it to train the next model; paid business tiers offer training opt-outs, so check the tier you are actually on. "Configurable"/"Commercial terms" rows reflect that paid business tiers of these products offer training opt-outs, check the tier you are actually on. Spot an error in this table?

ChatGPT (OpenAI)
What it does better than us: frontier model capability, the largest plugin and app ecosystem, voice mode, and a free tier. If raw capability on non-confidential work is the only criterion, buy ChatGPT.
The structural difference: OpenAI is a US company; whatever tier you pay for and wherever your data is stored, it remains within reach of US legal process under the CLOUD Act. For a regulated professional handling patient, client or employee data, that fact belongs in your DPIA, and "we selected the UK data residency option" does not remove it.
Microsoft Copilot
What it does better than us: deep integration with Word, Outlook, Excel and Teams, AI inside the documents you already have open. If your organisation lives in Microsoft 365 and your IG lead has signed off the jurisdiction question, Copilot is the convenient choice.
The structural difference: in June 2025, Microsoft France's director of public and legal affairs told a French Senate inquiry, under oath, that he could not guarantee European data would never be handed to US authorities without European consent, while noting it had never happened. We wrote about exactly what that testimony does and does not mean. It is the clearest public statement that residency commitments do not move jurisdiction.
Google Gemini
What it does better than us: integration with Google Workspace, very long context windows, and strong multimodal features. Same logic as Copilot: if you live in Workspace and the jurisdiction question is answered in your paperwork, it is a capable product.
The structural difference: Google is a US company; Gemini runs on Google-owned infrastructure. The CLOUD Act analysis is identical to the other two, the postcode of the data centre is not the variable that matters.
Claude (Anthropic)
What it does better than us: exceptional writing and reasoning, a very long context window, and strong coding. For non-confidential work where raw quality is the only criterion, Claude is excellent, and we say so.
The structural difference: Anthropic is a US company, so whatever tier you pay for and wherever data is stored, it stays within reach of US legal process under the CLOUD Act. That fact belongs in your DPIA, and a data-residency setting does not remove it.
Lumo (Proton)
What it does better than us: it is cheaper, with a genuinely useful free tier, it is backed by Proton's privacy reputation, and like us it never trains on your data. For a private personal assistant where the data is your own, it is excellent value and we say so.
The structural difference: Lumo is genuinely private, but by Proton's own account it still keeps your conversations, saved with zero-access encryption. Hush keeps no conversations or documents, runs on hardware we own in the UK, and ships profession-specific drafting plus a one-click audit-log export. For confidential regulated work, "no conversations or documents kept, in the UK, with a trail you own" is the distinction that matters.

Hush is a small company. Our models run on hardware we own, which is precisely why we can make the jurisdiction claims above, and also why we cap free trials at five at a time. We have no Word plug-in, no voice assistant in your earbuds, and no free tier. Conversation history is stored encrypted on your own device until you delete it, we do not pretend otherwise, and it is never used for training. If the comparison above matters to your organisation, that trade is the entire product.

What is the main difference between Hush AI and ChatGPT, Copilot or Gemini?
What they keep. On their consumer tiers, ChatGPT (OpenAI), Microsoft Copilot and Google Gemini keep a copy of what you type and may use it to train the next model, on cloud infrastructure you never see; their paid business and enterprise tiers offer training opt-outs or do not train by default, so check the tier you are actually on (reviewed July 2026). Hush keeps no conversations or documents: it runs its own models on its own hardware, not Big Tech, and never trains on what you type.
Is there a private alternative to ChatGPT?
Yes. Hush is a private alternative that runs on its own hardware, not Big Tech, never uses your content for training, and keeps none of your conversations or documents. Your chat history lives only on your own device, and you can wipe it in one click.
Is Hush AI more capable than ChatGPT?
No, for raw general-purpose capability, ChatGPT and the other frontier US models are stronger, and we say so. Hush's advantage is structural: it keeps no conversations or documents, runs on its own hardware not Big Tech, and never trains on your data. Choose Hush when it is private; choose a frontier model when it is not.
Does Hush AI use my data to train its models?
No. We keep no conversations or documents on our servers, we process what you send, then delete it, and never train on it. Documents and API requests are never stored; the web-chat history you choose to keep is encrypted on your own device and deleted the moment you delete it.
