AI fact-check claim extractor
AI writing tools are excellent at sounding authoritative and terrible at being reliably correct. The dangerous parts of an AI draft are its specific factual assertions — a precise statistic, a date, a named source, a quoted line — any of which can be confidently hallucinated. The fact-check claim extractor scans AI-generated text, pulls out every sentence that contains a verifiable claim, and presents them as a checklist so you can confirm each one against a real source before you publish. It runs entirely in your browser.
How it works
The extractor splits your text into sentences and scores each one for fact-check signals: numbers and percentages, calendar dates and years, capitalised named entities (people, organisations, places), text inside quotation marks, and citation or reference markers. Sentences carrying these signals are surfaced as claims, grouped by the type of evidence they contain, so you know what kind of source you need to confirm them. Sentences that are purely opinion, transition, or generic filler are left out, keeping the checklist focused on the statements that actually carry factual risk.
Tips and notes
- Prioritise numbers and citations. Invented statistics and fake references are the most common and most damaging hallucinations — check those first.
- Confirm against primary sources. Verify a date or quote at its origin, not against another AI summary that may share the same error.
- It is a first pass. Subtle claims phrased without numbers or names can slip through; read the full text too.
- Keep the checklist. Attaching the extracted claims to an editorial review gives you a defensible record of what was verified.
