What We Check
Review Length
Extremely short reviews (under 20 characters) are often fake. Authentic reviews typically provide more detail.
Min 20 charsCapitalization Patterns
Excessive caps (more than 30%) is a common sign of fake reviews and emotional manipulation.
<30% capsExclamation Marks
More than 3 exclamation marks often indicates artificial enthusiasm, common in low-quality fake reviews.
≤3 marksGeneric Language
Overused phrases like "best ever" or "highly recommend" are red flags for fake content.
≤1 genericWord Repetition
Repeated words appearing frequently can indicate automated or template-based fake reviews.
No patternsSpecific Details
Authentic reviews mention specific products, staff names, dates, or experiences. Vague reviews are suspicious.

All positive or all negative sentiment without nuance is suspicious. Real reviews typically show balance.
Balanced toneWord Pattern Consistency
Mixing very formal language with slang can indicate the review wasn't written by a single authentic person.
Consistent styleWhat Are Common Questions About Fake Review Detector?
Is this tool 100% accurate?
No tool is perfect. Our detector identifies common patterns in fake reviews, but some fake reviews may slip through and some authentic reviews might flag concerns. Use it as one signal among others when evaluating review authenticity.
Is my review data saved or shared?
No. All analysis happens in your browser. We don't send your review text to our servers or store it anywhere. Your data stays completely private.
What should I do if I find a fake review?
If you discover a fake review on Google, Facebook, Trustpilot, Yelp, Amazon, or another platform, report it directly to the platform. Most platforms have clear reporting mechanisms and take action against policy-violating reviews.
Can I use this to check my own business reviews?
Absolutely! Business owners use this tool to identify suspicious reviews about their businesses and can then report them to the review platform for removal.
What's the difference between "Needs Review" and "Likely Fake"?
"Needs Review" (40-70 score) means the review has some suspicious characteristics but isn't definitively fake. "Likely Fake" (0-40 score) means multiple red flags indicate the review is probably inauthentic.
Do you support other languages?
Currently, the detector works best with English text. Some checks (like generic phrase detection) are English-specific, though pattern checks work across languages.
