Every response grounded in HMRC and GOV.UK guidance — checked, linked and confidence-scored. If we can't cite HMRC for it, we won't say it. It's the difference between an AI that sounds right and one you can put in the client file.

Hallucination is the one objection that kills AI tax research. Footnote engineers it out — every answer passes four gates, and quality is enforced by a golden-evaluation CI gate, not vibes.
Your question searches a grounded corpus built exclusively from official HMRC and GOV.UK guidance.
The answer is drafted strictly from retrieved guidance — never from the model's memory of the open internet.
Every citation is checked against allowed official domains. Unverifiable sources never reach you.
Confidence is scored on every answer. Below threshold, Footnote says "I don't know" — and that's a feature.

Answers come from official HMRC and GOV.UK guidance only — a retrieval corpus curated for UK tax, kept fresh as guidance moves.
Every source is checked against allowed domains and linked. Drop citations straight into the client reply or the working papers.
See exactly how strong the evidence is behind each answer. Judgement stays with you — with the data to exercise it.
Low-evidence answers get refused, not invented. An AI that says "I don't know" is one you can actually trust with client work.
A golden-evaluation suite gates every release in CI. Answer quality is measured and enforced — not hoped for.
Nobody in this category has a decent mobile experience. Answer the client from the car park, with citations.
