Everything you need to know is in there. So is everything you don't.
So much to take in. What actually applies to you?
The answer you need is usually buried in documents written for everyone. Now I know works it out from your circumstances, one step at a time, and shows you every step.

Why not just use AI? Because it can't promise it's right.
Everything that matters to you. Nothing that doesn't.
AI reads it. An expert approves it. The rules decide.
That split is the whole idea. AI is brilliant at reading documents and explaining things in plain language. It just shouldn't be the one making the call.
AI may assist. Approved knowledge holds the authority.
What it changes for your organisation.
Tell the people it affects. Leave everyone else alone.
Usually a regulation changes and everybody rereads it. Now I know remembers each past case: the facts given, the rules used and the version applied. When the source changes it replays those cases against the new rules and works out exactly who is affected and how.
Illustrative only, not a forecast. Swap in your own headcount, costs and the share of people affected. Avoided errors, incidents and fines are not included and are worth measuring separately.
Anywhere the rules are written down and the answers matter.
From a ten-person practice to a national service. The size changes. The problem doesn't.
Trust comes from clear responsibility, not just clever technology.
