Anthropic's Claude is one of the best writing and reasoning models available, and for non-confidential work it's hard to beat. The single thing to know for confidential UK work is the same as for ChatGPT and Gemini: who can be compelled to hand the data over.
On 12 June 2026 a US government export-control directive ordered Anthropic to suspend its newest models, Claude Fable 5 and Mythos 5, for every foreign national. To comply, Anthropic disabled them for all customers worldwide. The company publicly objected — and complied anyway, because a US company has to.
That's not a knock on Anthropic; it's one of the most safety-focused labs there is, and it pushed back. It's the whole point of this page made concrete: a US-owned AI, however good and however well-intentioned, can be ordered by its government to cut off your access overnight. Hush runs on hardware a UK company owns — there is no US entity to serve such an order on. Read our full take →

Rows describe ownership and jurisdiction from public terms and filings as of June 2026. Anthropic is a US-incorporated company; the CLOUD Act (H.R.4943, 2018) applies to US providers wherever data is stored. Anthropic's commercial/API terms state inputs are not used to train its models by default — check the product and tier you use. Spot an error? Tell us and we'll correct it within one working day.
Claude is exceptional at long-form writing, careful reasoning and working over large documents, and it has a polished interface and developer tooling. For drafting, analysis and coding on work that isn't confidential, it's an outstanding choice and we won't pretend to match its raw capability.
Anthropic is a US company and Claude runs on US-owned cloud infrastructure, so it falls under the CLOUD Act wherever the data sits. For confidential UK work your DPIA can't truthfully say no US authority could be compelled to access the data. Hush runs on hardware a UK company owns in England — no US entity in the chain — which is what lets your paperwork say so plainly. A Microsoft executive conceded this exact point under oath; it applies to every US-owned provider, Anthropic included.
Check where your current tools land with the free CLOUD Act exposure checker — seven questions, no email, no tracking.
Choose Claude for the strongest writing and reasoning on work that isn't confidential, where your governance lead is comfortable with the jurisdiction position.
Choose Hush when you're drafting documents with patient, client or employee data and need a tool on UK-owned hardware outside US jurisdiction, with an audit trail you own. Hush drafts under your review — not a frontier-capability rival, and not an ambient scribe.
