The problem
The science is settled and the tests are being done. What fails is the end of it — where a result has to become a decision, made by one person, quickly, with no way to check what the literature says.
Projected annual cost to NHS England of admissions caused by adverse drug reactions.

Nobody reads a long page. So none of this is a long page — choose the part that matters to you.
AI is about to be pointed at a great many problems. This is one of the ones that matters. The knowledge that would prevent a large amount of avoidable harm already exists — it is simply not reaching the person holding the pen.
National pharmacogenomic testing is already being rolled out, and prescribing alerts are already being built. We are not trying to replace any of that. We are the layer underneath it.
Everything Generesis says is retrieved from published literature and guidelines. Nothing is generated from a model’s memory, and nothing unsourced is allowed through.
The first study needs no prospective trial and no identifiable patient. That is deliberate: it means a partner can say yes without a two-year approval.
Advanced does not mean clever. It means you can check it — every number on this page has a source, and every decision the system makes can be traced back to one.
