Why Claimer exists
Truth shouldn't need gatekeepers
In 2026, truth is fragmented. Fact-checkers write editorial verdicts. Prediction markets let you bet on outcomes. Community Notes works — but only on X. Source ratings grade outlets, not individual claims.
No platform combines all four. Claimer does.
The Two Dimensions
Every claim on Claimer separates two independent reader questions so the source trail stays distinct from the support and challenge evidence:
Did this person actually say this?
Verified through the original interview, tweet, article, or statement. A claim can be accurately attributed but still false.What support and challenge sources exist?
Shown through supporting and challenging evidence from multiple sources. A claim can have strong source coverage while its attribution remains uncertain.How it's different
vs. Fact-checkers
Snopes and PolitiFact use editorial teams. Claimer is community-driven — anyone can submit evidence. No editors issuing final truth verdicts.
vs. Prediction markets
Polymarket uses money to discover truth. Claimer uses evidence and sources. No betting, no financial instruments — just source-backed reasoning.
vs. Community Notes
X Community Notes works great — on X. Claimer is platform-agnostic. Any claim from any source can be assessed here.
vs. Source ratings
NewsGuard rates outlets. Claimer rates individual claims AND tracks individual contributor reputation over time.
Evidence quality matters
Not all sources are equal. Every piece of evidence is graded:
What we are NOT
❌ Not a social network. The primary UX is claim-centric, not people-centric.
❌ Not a prediction market. No financial instruments or betting.
❌ Not a news site. No editorial content or articles.
❌ Not a fact-checking org. The evidence record grows through source entries, not editor verdicts.
Transparency
🤖 AI disclosure
All AI-assisted analysis is clearly labeled. Every automated element is disclosed. We never hide when AI helps.
Source trail record
No black-box verdicts. Source entries show what supports, challenges, or contextualizes a claim.
🔗 Source chains
Every claim links to every source. Every source links to a URL. Nothing is hidden.
⚖️ Legal framing
All analysis uses "evidence suggests" — never "this is true/false." We present evidence, not verdicts.
