FactJudge
AI fact-check that shows the evidence, not just a verdict
Paste a claim. FactJudge splits it into checkable points, cross-references each with trusted web sources + existing fact-checks, and returns per-point verdicts + confidence scores + ranked sources. Runs in background with push. Free, 4 languages.
Hey Product Hunt! 👋
I built FactJudge because I kept hitting claims online and not having a fast way to check which specific parts are supported.
FactJudge takes any claim, article, or social post and:
→ Splits it into checkable points so you see which bits are actually in question
→ Cross-references each point against Google Search grounding + Google's Fact Check Tools API
→ Returns TRUE / FALSE / PARTIAL / UNKNOWN per point — and UNKNOWN really means UNKNOWN (no forced verdict when evidence is thin)
→ Ranks sources by credibility: official → major media → reliable → mixed → low
→ Shows a confidence score so you know when to trust the result
Built on Cloudflare Workers + Workflows. Long analyses run in the background and push a notification when done. Available in Japanese / English / Chinese / Korean.
What I care about: FactJudge doesn't claim to "know the truth." AI judgments are probabilistic — it shows you the reasoning, sources, and confidence so you can decide. It's a support tool for your own checking, not a verdict machine.
Would love feedback — especially edge cases where the verdict felt wrong or over-confident. That's exactly what I want to tune.
