About FactVerify

Evidence before opinion.
Verified in real time.

FactVerify bridges the gap between breaking headlines and primary evidence. We combine real-time AI verification with deep document retrieval to provide instant, auditable clarity on any assertion.

01Real-Time Engine

Instant AI verification

Paste any claim, viral post, or breaking headline. Our verification engine isolates the empirical assertion and cross-references authoritative records live to deliver an instant verdict, evidence summary, and confidence score.

02Deep Extraction

Beyond search snippets

We bypass shallow SEO summaries and blog consensus. Our engine directly retrieves and parses the underlying documents—court dockets, statutory texts, peer-reviewed journals, and agency datasets—directly from origin servers.

03User Privacy

Private research vault

Your real-time fact checks remain private to your account by default. Save, organize, and build an auditable personal evidence archive with 5 free automated checks every month, with no public indexing of your searches.

04Open Knowledge

Curated public archive

High-impact, peer-reviewed fact checks are curated into an open public library with structured ClaimReview schema for search engines, permanent audit permalinks, and ongoing freshness tracking.

The Architecture

How FactVerify verifies a claim.

Every check passes through a disciplined four-stage verification pipeline.

1

Proposition Extraction

Deconstructs conversational input, viral rhetoric, or articles to isolate the core testable claim.

2

Primary Grounding

Executes live web search grounding paired with full-document HTML DOM retrieval to access original records.

3

Coherence & Cross-Audit

Audits event chronology, contextual caveats, geographic boundaries, and contradictory counter-evidence.

4

Calibrated Verdict

Formulates an evidence-backed finding with an explicit confidence score and direct links to original documents.

Our standard

Clear enough to use. Transparent enough to trust.

Relevant sources. A long source list is not a substitute for evidence that directly addresses the claim. Primary documentary evidence carries the highest weight.

Visible uncertainty. Preliminary reporting and unresolved evidence are explicitly labeled with transparent confidence ratings rather than smoothed over.

Living records. Developing situations evolve. Published articles feature clear verification timestamps, revision histories, and reader update petitions.

Strict non-partisanship. Facts have no political affiliation. Evidence is evaluated purely on documentary integrity, without corporate, partisan, or ideological bias.

Verification badges

Primary source verification.

Primary Source Extraction. Applied to individual citations in our source trail when FactVerify retrieved and parsed the full underlying HTML document—such as a court filing, statute, federal register notice, or official agency record—rather than relying solely on third-party search snippets.

Primary Source Verification. Details how the assessment was audited against full document text. When deeper primary records uncover decisive context, timeline discrepancies, or qualifying details, the verdict is refined to reflect the source record.

Primary Source Verified. The top-level certification confirming that a fact check passed our comprehensive full-text document eligibility audit: primary sources were directly retrieved, audited for event coherence, and evaluated against strict domain-tiered quality standards.
