How it works

  1. 1. Ingest

    Paste text, a link, a reference list, or a question.

  2. 2. Extract

    Verfiai identifies individual claims or references.

  3. 3. Research and evaluate

    Verfiai searches available public sources and evaluates the evidence.

  4. 4. Review and export

    Open sources, inspect conflicting evidence, and export a traceable report.

Limitations: Verfiai can't read paywalled sources, can miss recent events, and AI engines can misread evidence. Treat results as a starting point and open the sources.

Built for research that needs an audit trail

Researchers

Validate citations and investigate the evidence behind claims before submission.

Journalists

Compare sources and preserve a clear evidence trail for fact-checking workflows.

Business teams

Verify competitor claims, validate market figures, and generate sourced intelligence briefs for decisions and presentations.

Developers

Prepare for structured research and verification workflows. API access coming soon.

Evidence, not black-box answers

  • Verfiai searches available sources and evaluates the evidence for each claim.
  • Results are labelled Supported, Contradicted, Mixed evidence or Insufficient evidence.
  • Confidence reflects the available evidence: source quality, diversity, recency and consistency of assessment.
  • AI agreement is one signal, not proof that a claim is definitively true.
  • Open the sources, review the context, and apply your own judgment for important decisions.

Designed for transparent verification

Verfiai extracts claims and gathers relevant publicly available evidence, recording source links, excerpts and retrieval times. An AI model assesses source excerpts individually; provider failover supports availability and is not independent multi-model consensus. Outputs are decision support, not definitive truth judgments. Search coverage may be incomplete due to paywalls, indexing limits or recent publication dates.

Frequently asked questions

Is Verfiai free?

Yes. Verfiai is free until October 13, 2027 under fair-use limits. After the one-year community-access period, Pro and Teams plans will be introduced. Existing users will receive advance notice.

Does Verfiai tell me what is true?

No. Verfiai provides verification support by surfacing available evidence. It does not make definitive truth judgments. Review the sources and apply your own judgment.

How are sources selected?

Fact-checks and reports use live web search, re-ranked by keyword relevance. Citation scans use Crossref's public records of published papers, including retraction notices.

What does "Mixed evidence" or "Insufficient evidence" mean?

The sources found are ambiguous, conflicting or too thin to clearly support or contradict the claim, so it needs manual review. It isn't a judgement that the claim is false.

What does confidence mean?

It reflects the strength of the available evidence — source quality, diversity, recency and whether the AI engines agreed. It is not a guarantee of truth.

Can Verfiai access paywalled sources?

No. It can only evaluate publicly accessible content. Paywalled or offline sources cannot be read.

How does Verfiai handle conflicting evidence?

Two AI engines review the same retrieved excerpts. If they materially disagree, a third engine reviews the conflicting evidence, and conflicting excerpts are shown side by side. AI agreement is one input to confidence, not proof of accuracy.

Is my submitted text private?

Signed-in reports are saved privately to your account. Your text is sent to search and AI providers to produce results. Don't submit confidential, regulated or unpublished material.

What are the free-plan limits?

A free account gets 3 reports, 3 fact-checks and 3 citation scans a month. You can try a claim check without an account. Verfiai is free until October 13, 2027, subject to fair-use limits. Academic, educator and high-volume users can request extended access at hello@verfiai.app.

Can I export or share reports?

Yes — Word, Markdown or PDF, plus read-only share links you can turn off. Community exports carry a Verfiai watermark. Paid checkout is currently unavailable.
