FactVerify vs Veritier

FactVerify is a web-based service that automatically checks claims, viral posts, breaking headlines, articles, webpages and documents. It returns an evidence summary, confidence percentage and linked sources. Its four-stage process identifies a testable proposition, uses primary records, examines context and counter-evidence, then produces a calibrated verdict. The retrieval engine can parse court dockets, statutory texts, peer-reviewed journals and agency datasets; listed primary sources also include SEC filings and government datasets. Confidence percentages describe the coherence and corroboration available when analysis runs, not mathematical certainty. Accounts include five automated checks each month, while the homepage offers one check without an account. Real-time checks are private by default and are not indexed by search engines. Selected checks enter a public library with ClaimReview schema, permanent audit links and freshness tracking. FactVerify notes that automated models can miss temporal nuance, sarcasm, complex statutory references or breaking developments, and says the service is informational rather than legal, medical, financial, tax or investment advice.

Veritier extracts checkable claims from text, URLs, PDFs, and images, then compares them with live web evidence or private references. Results provide a verdict, confidence score, plain-language explanation, and source links. The service is available through a REST API, MCP server over Streamable HTTP, local stdio proxy, and browser interface, with parsing and OCR built into its pipeline. The attest_action endpoint checks named records such as npm, PyPI, CourtListener, SEC EDGAR, and the U.S. Code, blocking actions when records cannot be confirmed. Attestations create Ed25519-signed Claim Credentials that can be checked through JWKS and revoked; credentials remain for 400 days. Requests can use webhooks and signed retries. Free-tier text may be retained and used to improve models, while paid-tier payloads are processed ephemerally and excluded from foundation-model training. The free tier allows 25 verifications monthly; paid plans start at $19.99 a month. Verdicts and confidence scores are probabilistic.
