Add fact-check comments to claims
River's Fact-Check Comment Adder reads your document, identifies factual claims, and adds verification comments. For each claim, the AI indicates whether it found supporting sources or if the claim appears disputed or unverifiable. Whether you're fact-checking articles before publication, verifying sources, or reviewing content accuracy, you get systematic verification comments throughout your document.
Unlike simple spell-checkers, we focus on factual accuracy. The AI understands what constitutes factual claims (statistics, dates, attributions, historical facts, scientific assertions), distinguishes facts from opinions, and adds comments noting verification status. You get focused feedback on accuracy, not style or grammar. This is a verification aid, not a replacement for thorough fact-checking.
This tool is perfect for fact-checkers reviewing articles, editors verifying claims before publication, journalists self-checking their work, and anyone responsible for accuracy. If you need systematic verification but face time pressure, or if you want to catch obvious errors before human fact-checking, this tool helps. Use it on every piece before publication as part of quality control.
What Makes Fact-Checking Essential
Fact-checking protects credibility and serves readers. One unchecked error damages trust that takes years to build. Effective fact-checking means verifying every factual claim (statistics, dates, quotes, historical facts, scientific assertions), checking primary sources when possible, confirming spelling of all names and titles, verifying attributions, and noting when facts are disputed or unclear. Weak fact-checking relies on secondary sources, accepts obvious facts without verification, or skips claims that seem minor. Strong fact-checking treats every factual assertion as requiring verification.
The best fact-checking follows systematic process. Identify every factual claim in the piece. Find primary sources (original studies, official documents, direct statements). Verify exact numbers and dates. Confirm proper names and titles. Check for missing context that would change meaning. Note when sources disagree or facts are disputed. Use trusted reference sources. Never rely on single sources for important claims. When facts can't be verified, flag for reporter or delete claim. If something seems wrong, it probably is. Trust your instincts and verify thoroughly.
To improve accuracy, build fact-checking into the workflow (not afterthought before publication). Give fact-checkers time to work properly. Maintain relationships with reliable sources. Keep updated reference materials. For breaking news, publish what you can verify and update as more confirmed. Label disputed claims clearly (X claims, but Y disputes). Correct errors promptly and transparently. Credibility is journalism's currency. Protect it through rigorous verification. Readers may forgive bad writing. They won't forgive false information presented as fact.

Frequently Asked Questions
Is this a replacement for human fact-checking?
No. This is a verification aid that speeds initial review. You still need human fact-checkers to verify thoroughly, check primary sources, understand context, and make judgment calls. Use this to catch obvious issues and identify claims needing verification. Never publish based solely on AI fact-checking. Human verification is essential for accuracy.
How accurate is the web search verification?
It provides starting points, not definitive verification. Comments note what sources were found or if claims appear disputed. You must verify all important claims through primary sources and trusted references. The AI can miss nuance, misinterpret context, or find incorrect information. Treat comments as flags for human review, not final verification.
What types of claims does this check?
Factual assertions like statistics, dates, attributions, historical facts, scientific claims, and verifiable statements. It doesn't fact-check opinions, predictions, or subjective statements. It focuses on claims that can be verified or disputed through sources. Opinions and analysis require editorial judgment, not fact-checking.
What if the AI marks something as disputed that's actually true?
Investigate thoroughly. Sometimes true facts appear disputed online due to misinformation. Sometimes the AI found conflicting information requiring deeper verification. False positives happen. Your judgment as fact-checker is essential. Research claims flagged as disputed to determine actual accuracy. The tool identifies potential issues. You determine truth.
Can this verify quotes and attributions?
It attempts to find sources for attributed statements, but verifying quotes requires checking original sources, recordings, or transcripts. Never rely solely on web searches for quote verification. Contact original sources when possible. For important quotes, verify through multiple methods. The tool flags attributions needing verification. You do the thorough checking.
