Check AI hallucinations on Chrome before you trust or share an answer.
Start with one factual sentence from a ChatGPT answer, AI summary, or generated citation list, keep the exact wording and source context, then run a FactSentinel check before you forward, cite, edit, or publish it.
Do not verify the whole AI answer at once.
AI answers can mix solid background, plausible filler, stale facts, invented details, and citations that do not support the sentence. A practical browser workflow starts with one risky claim and checks whether the source trail supports it.
1. Pick the claim
Select one factual sentence, citation, quote, statistic, legal statement, medical statement, or source summary from the AI output.
2. Run FactSentinel
Use the extension or web checker to review verdict, confidence, model agreement, reasoning, caveats, and source links.
3. Inspect sources
Open the evidence trail and decide whether the AI answer is supported, mismatched, incomplete, outdated, or unsafe to share.
AI answer claims worth checking first.
The best first checks are concrete enough that you can inspect source evidence after FactSentinel gives you a structured pass.
Generated citations
- Article titles, books, reports, journals, or cases that look real but may not exist.
- Sources with missing authors, dates, publishers, or working URLs.
- Citations that point to a real source but support a different claim.
High-impact advice
- Medical, legal, tax, financial, safety, or compliance statements.
- Instructions that cite policy, law, scientific findings, or official guidance.
- Answers that sound certain but give no primary source.
Shareable claims
- Numbers, rankings, dates, quotes, and named attributions.
- Summaries you plan to publish, email, teach, or put into a report.
- Claims copied from an AI answer into a public page or social post.
What a useful hallucination check should show.
The result should make the next action obvious: trust with caveats, open a source, rewrite the claim, ask for stronger evidence, or stop before sharing.
Evidence
- Source links tied to the exact AI sentence.
- Caveats when the source trail is thin.
- Reasoning you can inspect and challenge.
Agreement
- Visible confidence and model agreement signals.
- Reasons for disagreement or uncertainty.
- Warnings when the answer needs manual review.
Decision
- Keep, edit, remove, or escalate the claim.
- Replace weak citations with primary sources.
- Share only after the evidence supports the wording.
