TrustStars — Trustworthy Ratings

See the star rating you can actually trust. A Wilson confidence score reveals when a high average is just too few reviews.

A 4.8 from 12 reviews looks better than a 4.4 from thousands — but it isn't. With few ratings, a star average is just noise. TrustStars applies the Wilson confidence score to a product's rating and review count, so you see the rating you can actually trust: • On Amazon product pages, a badge appears next to the rating showing the confidence-adjusted "trusted score," a confidence level (High/Medium/Low), and the likely star range. • Click the toolbar icon to compare products side by side — add them manually, or hit "Scan this page" to pull the rating off the current Amazon tab. They're ranked by trusted score, with the safest pick highlighted. Private by design: no accounts, no analytics, no ads, no tracking, and no network requests. It only reads the rating numbers already shown on the page you're viewing, and your comparison list is stored locally on your device.
