How it works

Three steps. Zero effort.

01

Visit an Amazon product page

Open any product on Amazon.com. LegitScore activates automatically — no button to click.

02

We analyze the reviews

We examine review patterns, verified purchase ratios, language signals, and rating distribution using AI and static analyzers.

03

See your verdict instantly

A badge appears with a verdict — Strong, Moderate, Weak, or Unreliable — and a plain-English summary of what we found.

What we analyze

Six signals that reveal the truth

✓

Verified Purchase Ratio

We measure what percentage of reviews come from verified purchases and flag outliers against category averages.

◷

Review Velocity & Timing

A flood of reviews in a narrow window is a red flag. We detect unnatural spikes in review submission dates.

≡

Language Pattern Analysis

Repeated phrases, templated language, and unusual sentence structures across reviews are signs of manipulation.

▲

Rating Distribution

Healthy products have organic 1-to-5 star distributions. We flag suspiciously polarized or J-curve patterns.

◎

Reviewer Profile Signals

We look at reviewer history patterns to detect accounts that only leave 5-star reviews across unrelated products.

✦

AI Synthesis

GPT-4 reads the top reviews and produces a plain-English badge line capturing fit, quality, and caveats — without the fluff.
