Built to earn the signature, not just the click.
Anyone can run a citation past a search box. CiteProof exists for the moment a partner signs a brief: every flag is evidence you can inspect, every limit is stated on the page, and the checker itself cannot hallucinate — no AI model ever sees your brief.
What you get that a search box doesn't
- Whole-brief gate. Paste the brief once; every citation and quoted passage is extracted and checked in one run, with a counts line proving what was read.
- Identity, not just existence. A fabricated citation can land on a real reporter location occupied by a different case. We compare the name, court and year your brief claims against the record — and show both sides when they differ.
- Quote forensics (paid). Side-by-side passages with pin cites, match confidence, guardrail reasons, and word-level diffs for dropped negations and changed numbers.
- A sign-off workflow. Flags become review tasks with a progress count, a copyable review log, and a downloadable Verification Record for the file.
- Honest boundaries. Good-law verdicts, support-for-proposition and unpublished/state-trial coverage are things we don't do — and the report says so instead of guessing.
Measured, not promised
Project measurements, October 2026 runs against real case text. Read them with the caveats — a small holdout bounds the false-clean rate; it does not certify it.
- 0 false cleans on 6 bad dev items and 15 bad holdout items (rule-of-three bound reported, never a rate).
- 18 of 18 planted citations extracted across 6 synthetic briefs.
- Identity comparison judged on ~37.5% of full citations where a usable party name is available — the rest get existence-only checking, stated as such, never a silent pass.
How this compares
Capability by capability, against the industry standards attorneys actually use. Competitor cells describe vendor-published features and third-party reported pricing, October 2026 — confirm current details with each vendor. We publish the rows where we lose on purpose: knowing what CiteProof doesn't do is part of using it safely.

Reading the table: CiteProof wins the single row of checking one brief tonight with no procurement. The subscriptions win every row about depth. Buy us for the gate before filing; keep the citator for good law.
When not to pay us
- You need to know whether authority is still good law — buy the citator check, or use our citing-history links as the starting point.
- Your brief is mostly statutes, regulations or secondary sources — we check reported opinions.
- You need a certificate of diligence — our record documents what was checked; it proves nothing about your review.
