GPAtlas Ask Expert · The Evidence Standard

Ask Expert is built to find published UK guidance and show you exactly where every point came from. Here is what that produced across our most recent answers, and how we measured it.

How Ask Expert works differently from other AI tools

This is a difference in how they are built, not a score. It is the reason the numbers above are even possible.

Other AI tools

You ask a question

It writes an answer from what it learned during training

It may then look for citations that fit the answer

Those citations may not exist, or may not be UK guidance

How many sources sit behind an answer

Nearly nine in ten answers are supported by the full set of eight retrieved sources, so the median above is the norm and not an average hiding a long tail.

From our pilot to now, we keep measuring and fixing

These are the same three measures during our pilot study and after our most recent rebuild of how Ask Expert finds its sources. We publish the pilot figures too, because a number with nothing to compare it to proves very little.

What these figures are not.

They describe where our answers come from and how well they are attributed. They are not a measure of clinical accuracy, and nothing here is a claim that Ask Expert reaches a better clinical judgement than anyone or anything else. Ask Expert finds and presents published guidance; the clinical decision is always yours.
