The only domain-specific piece is the source of record. Two verticals are proven; three more are in active build; the rest are a registry away.
Fabricated & mis-cited case law — the Mata mode. 366 cites, frontier 7–56% bad, gate 0.
We verify a citation exists, is correctly identified and is accurately quoted — not that it supports the proposition it is cited for. Scope.
Figures that don't match the filing — or don't match your own model, where no public registry exists. 5,000+ claims, frontier 33–67% on dirty data, gate 0/6,000.
Fabricated PMIDs & trial ids; real id, wrong finding; invented studies.
Fabricated DOIs; real DOI attributed to the wrong paper.
Hallucinated CVE ids and invented packages ("slopsquatting") — a distinct error mode.
Fabricated patent/docket numbers, wrong approval status, mis-stated official figures.
A new vertical is a new source of record — not a new product. The gate, the model-independence, and the compounding memory are shared across every one of them, and each is held to the same standard before we call it proven.

When a wrong citation isn’t an option. AttestAlly.
A citation can be checked against the court’s docket. A portfolio company’s capacity factor cannot — no registry holds it. So upload the report and the model, accounts or exhibits behind it, and we reconcile the figures against your own records: what agrees, what disagrees (quoted against the source row), and what we could not check and why.
Corroboration against your own documents — a narrower claim than verification against an external register, and the certificate says so. From $5.50, capped at $9. Pricing · Try it
Strongest where an authoritative registry exists — but valuable anywhere accuracy matters and facts can be checked.
Every citation resolved to the real case. Catches the Mata-class error before a judge does.
Registry: CourtListenerEvery reported figure checked against the filing of record. A wrong number can't propagate into the valuation.
Registry: SEC EDGAR / XBRLClaims, figures, and citations verified end-to-end before they reach the deal team.
Multi-registryEvery study, statistic, and identifier checked. Fabricated or mis-attributed references flagged.
Registry: PubMed / FDAFacts and figures reconciled to source before submission, with a full audit trail.
Multi-registryCited literature and reported data verified — reviewers won't find an error you missed.
Registry: PubMedEvery quote, statistic, date, and citation fact-checked. We verify the facts — we don't write or grade the argument.
Fact & citation checkIf it contains claims that can be checked against a source of record, AttestAlly can verify it.

A deal memo, fund letter or board pack usually has nothing an external registry can resolve — no ticker, no filing reference, no reporter citation. Most verification tools stop there. We check the document against itself.
Segment figures that don’t add to the stated total, and balance-sheet identities that don’t hold.
A share stated as a percentage of a number that is also in the document — and doesn’t reconcile.
A stated change that the two figures either side of it do not produce.
Measured on our benchmark corpus: 0 false accusations across 107 registry-free documents that were correct, and 89.1% of documents carrying a planted arithmetic error were caught. Those figures are ours, from our own corpus — treat them as indicative.
