The evidence, in brief
Head to head with big AI
It gives fewer wrong answers than the big models. Roughly one ninetieth as many.
Same general-knowledge questions for every system. When Kinesthetic isn't sure, it says so instead of guessing. It gives the same answer every time, and every step can be checked.
Wrong answers, same test
In a sealed blind test, 99% of the answers it gave were right, with a 0.7% error rate and 0 made-up answers. 0 fabricated citations, 0 invented medical codes.
Faster, cheaper, and it doesn't want your data
About 4,000
answers a second on one ordinary workstation, no GPU. About 350 million a day.
~8,000x less energy
per question, estimated: about 0.00003 Wh against Google's own published 0.24 Wh for a median Gemini text prompt (Google, Aug 2025).
An order of magnitude cheaper per question than frontier AI APIs. As a search layer: 1 wrong answer against 14 for standard AI search, and 50 to 456 times faster.
Its own language
We're moving the engine onto a programming language we wrote ourselves. On the parts moved so far it gives exactly the same answers, 5 to 45 times faster.
Your questions are answered from public, authoritative knowledge. It does not need, keep or learn from your data.
Who it's for
Every field it has reached so far.
Government and the public
Every rule of government, in plain English and Welsh. Ask what the law says today, and get the answer with the law it came from.
Already held: tax, pensions, benefits, employment and immigration rules and tables; national planning guidance; workplace guidance; online safety; building safety.
Being added from GOV.UK: tax, benefits, pensions, work, housing, immigration, planning, transport, environment, health, justice, education, defence and international. Every HMRC manual, about 37,000 guidance pages, 4,900 forms, travel advice for 226 countries, medical safety alerts, drug safety updates, product recalls, accident reports, statistics releases and 1,700 international treaties.
Health
Medical Prism reads, sees, simulates and watches. Its coder, Clinfound, reads a clinical note and proposes the right codes, showing the words each one rests on. It never invents a code. A person always decides; it proposes.
Every penny of profit we make from government contracts goes back into NHS trusts where it's needed most. The NHS pledge →
147 health coding systems across about 90 countries mapped. Medicines knowledge: 14,500 medicine labels, interactions, lab tests, gene-based prescribing guidance, 30,000 clinical trials and NHS condition information, all cited.
Business analytics and research
Kin Analytics knows every UK company: who owns it, who advises it, how it is growing, what it has won, and who has a reason to hear from you today. The same joined-up, sourced picture of the UK is open to research: where public money goes, how a change in the law lands, which places are growing. Every fact marked with its source.
Also for AI agents: Guard stands in front of an agent and blocks hijack attempts without reading your private data. Hijacks fell from 43% to 0% with the guard in front, on an independent open benchmark with a live agent.
Learning
Lessons for every key stage of the national curriculum, and university-level knowledge across 40 subjects. Safe for children, because it only answers from sources it can show. For schools, built with teachers, we make learning tools better and cheaper than what they pay for today, and every penny of profit goes back into the schools that need it most, the same pledge we make to the NHS.
Translation, too: human-quality phrasing, scoring 86 in Italian, 75 in German and 74 in French on the standard translation-quality scale (chrF, out of 100), about twice the quality of word-for-word translation. 51 languages, with numbers, names and terms guaranteed unchanged. A new language takes minutes.
Creators and the studio
A studio that builds a brand and keeps it consistent across everything a business needs, with mockups and assets ready to use. Bashy and the cast are its own characters, owned by Archez. Our own light, physics and animation engines run on ordinary computers, with no GPU farm.
Science
The same method works beyond law and language: maths, astronomy, water, chemistry, climate, imaging, physics and translation, with every number traced and every caveat beside its figure.

Our charter
The A.I. we were promised, and the promises it keeps.
“This is the AI people were promised.”
Ten plain commitments for Prism and for Archez, the company that makes it. Not legal text. Written down so you can hold us to them.
- Mission over money. Money funds good work; it never comes before human dignity.
- The same help for everyone, whoever they are and whatever they can afford.
- We never take people's work. We cite our sources and credit everyone whose freely given work we learn from.
- Your data is yours. Never sold, never shown to advertisers, no addictive design.
- A tool, not a mind. It proposes, never acts on its own, and every answer is explainable.
- One hard line: it will never be used to kill.
