Fake Review Checker — Free & Transparent
Paste a review page URL and the reviews themselves, and get a transparent signal checklist — every check shows exactly how it was computed. No verdicts, no black box, no sign-up. Everything runs in your browser.
This tool shows transparent signals — never a verdict, and it cannot remove or report reviews for you. Everything runs in your browser; no checks are uploaded. Free and unlimited.
The signals behind fake reviews
Rating distribution shape
Natural review distributions spread out. A wall of 5-star reviews with almost nothing below is the strongest public red flag.
Wording & specificity
Real buyers mention what they used the product for. Copy-paste phrases and short generic praise cluster around paid review schemes.
Timing & bursts
A sudden burst of near-identical reviews within days of a launch — or after a rating dip — is worth a closer look.

Can this tool tell me if a specific review is fake?
No — and neither can any tool, honestly. Fake-review detection from public signals is probabilistic. What we give you is a transparent checklist of patterns that research has linked to review manipulation, with the exact computation shown for every signal, so you can judge for yourself.
Can you remove fake reviews from my listing?
No. Paying for review removal violates Amazon's terms of service, and we don't offer it. If you believe reviews violate Amazon's policies, report them through Seller Central — that's the compliant path.
Does this work on reviews from other sites?
The URL-level checks are tuned for Amazon. The paste-based checks — rating distribution, generic praise, repeated wording — work on reviews from any marketplace: just paste them in.
Is my data uploaded anywhere?
No. Every check runs locally in your browser. Nothing you paste is sent to our servers, and nothing is stored.
