Per-claim verification. Citations in your style. Evidence for every verdict. Built for journalists, editors, book publishers, longform writers, podcast producers, and screenwriters.
KSJ Three-Model Fact-Checking · ICD 203 · UK PHIA · ALCOA
These are the kinds of names that cross a reporter's desk every week. Enter one and MentionFox returns a profile where every claim links back to where it came from — a verdict, the evidence behind it, and citations in your house style.
"I ran that program for eight years and we never missed a single audit."
"There's no connection between me and that company. I've never had any involvement with them."
"I have always supported this position. My view on it has never changed."
No black box. You start with a name and end with a sourced, cited profile where you can stand behind every line.
Type the source, subject, or public figure you're writing about. One name is enough to start.
MentionFox assembles roles, dates, affiliations, and the record into one profile — every claim linked to the evidence behind it.
Each factual claim gets a verdict and confidence tier. The network around the subject is mapped, with the timeline laid out so contradictions surface.
Export the profile with citations in your house style. Ship the piece knowing each line points back to where it came from.
Each surface returns a sourced, cited result — never a guess, never an unattributed claim.
Turn a name into a structured profile: roles, dates, affiliations, reputation, and sentiment — every line cited. Run a person profile.
A reader-ready profile that lays out the verdict, the evidence behind it, and citations in your house style. See a sample dossier.
For the person at the center of a story or a deal: claim-by-claim verification with a confidence tier on each. Open the vetter.
A home base tuned for reporters — the surfaces you reach for on deadline, in one place. Open the journalist den.
A profile pulls from many surfaces at once, so the network and timeline come back whole rather than one thread at a time. See coverage.
Every verdict ships with citations pre-formatted in APA, MLA, Chicago, Bluebook, or AMA — paste straight into your draft. See all features.
Working a name by hand means hours across tabs with nothing linked together. Generic people-search sites hand you an unsourced data dump you can't put in print. MentionFox returns one profile where every claim carries its evidence.
Hours of open tabs, scattered notes, and a network you're holding in your head. The facts may be right, but nothing is linked, nothing is dated, and you rebuild it from scratch for the next name.
An unsourced dump of addresses and relatives with no verdict, no confidence, and no citation. You can't stand behind a single line of it on the record, so it never makes the piece.
One sourced profile: claims verified with a confidence tier, the network mapped, the timeline laid out, and a citation on every line in your house style. Vet a subject or see a sample.

The Verification Vetter scales from a 1,200-word filing to a 280-page manuscript. Three tiers map to budget and rigor.
You paste it into Verification Vetter. In under 3 minutes, you see 23 factual claims, 19 verified with primary sources, 3 flagged "low confidence — verify by hand," and 1 flagged "citation broken — author claims a 2019 study, link is dead." You ship the piece with confidence.
Traditionally you'd skip fact-checking or pay a freelancer $5K-$20K. Instead, you run the manuscript through Verification Vetter at $40/page = $11,200 — but with primary-source-callback simulation, every claim flagged for human pre-pub verification, and citation suggestions in Chicago style. Same rigor as the New Yorker's fact-checking department.
You upload the audio. Verification Vetter transcribes it, identifies every checkable claim by speaker, verifies against public sources, and returns a timestamped report. "Claim at 14:32 ('the company had 12,000 layoffs that year') — verified by Reuters Aug 2024." Ship without legal fear.
Verification Vetter cross-checks every factual claim against public record, flags defamation risk per claim (is this person a public figure? Does this claim imply criminal or immoral behavior? Is it sourced?), and produces a "dramatic license inventory" showing what's documented vs what would require invention. The entertainment lawyer's job goes from $500/hour to a final review.
No black-box scoring. Each verdict shows the source URLs, the matching passage, the confidence tier, and citations pre-formatted in the style you picked.
One page = 250 words. Drop in either words or pages and the calculator handles the rest.
Upload the whole book at once and the per-page rate drops. Bulk discounts apply automatically to manuscript-mode uploads.

A 280-page book at Magazine tier: 280 × $32 = $8,960 (was $11,200 at flat rate — save $2,240). Cached re-runs of the same manuscript are free for 90 days.
Same engine, different surface. Each vertical gets its own walkthrough plus pre-set tier defaults.
