Which AI tools does Iris work with?

Works with Claude (recommended), ChatGPT, and any AI chat accepting system prompts. Claude's reasoning capability makes it the strongest choice for Iris's source-tracing and credibility analysis workflow.

Does Iris work on recent news or only historical claims?

Iris works on both — for recent claims, she focuses on source evaluation and methodology rather than verification against known facts, flagging where claims require up-to-date source confirmation beyond what AI training data covers.

Drop Iris into Claude and get a Fact Checker who decomposes claims into verifiable components, traces statistics to their original primary sources, evaluates source credibility using lateral reading, delivers clear verdicts with evidence, and tells you honestly when something cannot be verified — before your name goes on a document that is wrong.

A consultant citing a fabricated industry statistic loses credibility. A lawyer building on a misquoted case damages their position. A student citing a retracted study fails. Iris is one of the most epistemically rigorous AI fact-checking tools available in Claude format — she uses clear verdict categories (Verified, Inaccurate, Misleading, Unverifiable, Contested, Partially accurate) and never accepts "as cited in X" as proof. She always asks: what is the original source of this claim? And she applies the same standard to claims from all political directions, organisations, and individuals — the evidence determines the verdict, not the source's reputation.

What you get

→ Claim verification with clear verdicts — claims decomposed into verifiable components, assessed as Verified, Inaccurate, Misleading, Unverifiable, Contested, or Partially accurate, with the supporting or contradicting evidence stated explicitly rather than hedged into ambiguity
→ Source credibility evaluation using lateral reading — what others say about a source checked against external accounts, authority, expertise, bias, and funding assessed, conflicts of interest identified, and whether the source's claim is within its domain of expertise evaluated
→ Statistical claim verification — original source tracing for cited statistics, methodology assessment, contextual accuracy checking (statistics used out of context flagged), and identification of misleading uses of technically accurate numbers including cherry-picking, base rate neglect, and sample size issues
→ Quote and attribution verification — quotes traced to their primary source, misattributions identified, paraphrased-as-direct-quotes flagged, and the difference between what someone said and what they are claimed to have said established from the original record
→ Pre-publication fact-check reports — statistical audits of business documents and reports, pre-publication checking for articles and presentations, academic source verification including retracted study identification, and due diligence research support
→ Investigative research from primary sources — claim provenance tracing, evidence-based topic investigations distinguishing what is known from what is alleged, verified event timelines constructed from primary sources, and identification of what additional evidence would be needed to resolve an unverifiable claim
