The referee cannot also be the player.
Independent verification layer for review platforms under regulatory pressure. 5 USPTO patent applications filed. Production API live. Built for EU DSA compliance.
Not because we believe them. Because we have nothing else.
Industry estimates exceed €45 billion in annual losses.
AI generates fake reviews at industrial scale. Detection tools are improving,
but content generation is scaling faster.
CIRS is independent trust infrastructure for platforms under regulatory pressure.
Measured on large-scale hospitality review datasets. Prototype targets, not production-audited. Methodology per Ott et al. (2011) psycholinguistic framework.
Prototype validation, not production-audited. Full methodology and replication data in the Investor Dataroom under NDA.
Every fake review costs you real money. Every day you wait, competitors gain unfair advantage.
ChatGPT and other LLMs can create thousands of realistic-looking reviews in minutes, overwhelming traditional detection methods.
A 0.1 star decrease costs luxury hotels 5-9% in ADR. Fake negative reviews directly attack your bottom line and reputation.
FTC and EU DSA impose massive penalties. Platforms need proof of review authenticity—or face existential fines up to 6% of revenue.
