We use AI-powered technology to protect trust and platform integrity

At trustrating.ai, we use advanced technology to help protect the integrity of our platform and support reliable TrustScores and customer reviews.

We do not fact-check every individual review or verify every specific claim, because reviews reflect each customer’s personal experience and opinion. However, we may mark a review as “Verified” when we can confirm that a genuine interaction with the business took place.

To help keep reviews trustworthy, every review on our platform — verified or unverified — is screened by our automated systems. These systems are designed to detect content that may breach our guidelines, including reviews that appear not to be based on a genuine customer experience.

While our technology helps us identify and remove suspicious or non-compliant content, no system is perfect. If you notice a review that you believe we may have missed, you can report it for further review.
