Why Check Claims Before Publishing?
AI-generated content has a 17-34% claim error rate. The claims that look most confident are often the ones most likely to be wrong — AI uses 34% more confident language when hallucinating.
Paste your claim
Any statistic, quote, factual assertion, or sourced claim you want to verify.
AI evaluates the evidence
The model checks the claim against known facts, assesses whether cited sources are real, and flags overclaiming.
Get a clear verdict
Verified, Partially Verified, or Challenged — with the correct version and an explanation of what's wrong.
Research shows 47% of ChatGPT-generated citations are inaccurate or completely fabricated (PMC 2024). Checking claims before publishing prevents the correction email nobody wants to send.
Example Check
"Intermittent fasting reduces inflammation by 70%"
Published studies show 28-30% reduction in CRP markers specifically, not 'inflammation' broadly. The 70% figure appears nowhere in peer-reviewed literature. This is a common overclaim in health content.
Intermittent fasting has been shown to reduce CRP inflammation markers by approximately 28-30% in clinical studies.
No specific source is cited. The claim appears to conflate multiple studies with different findings.
Frequently Asked Questions
Paste any factual claim — a statistic, a sourced quote, a number. The AI evaluates it against known evidence and tells you if it's accurate, partially accurate, or wrong. You get the correct version if it needs fixing.
ChatGPT tends to agree with claims you present to it — a phenomenon called sycophancy. This tool is specifically prompted to challenge claims, not confirm them. It checks evidence, not vibes.
A single model catches obvious errors but has blind spots. This free tool uses 1 model. TrueStandard's paid version uses 4 independent models to cross-verify every claim in your entire article — catching errors that any single model would miss.
We record submission metadata for rate limiting. Your claim text is not stored. We use enterprise API agreements — your content is never used for model training.
This tool checks 1 claim with 1 model. TrueStandard checks every claim in your entire article with 4 models, shows where they disagree, flags sycophancy, and generates a shareable verification report. It's the difference between checking one ingredient and having the whole dish reviewed.
