Adds price history charts and the option to be alerted on price drops to all supported Amazon sites.
See the star rating you can actually trust. A Wilson confidence score reveals when a high average is just too few reviews.

Track rating movement over time to see whether quality signals remain stable.
Compare 1-day, 7-day, and 30-day net growth and growth rate.
Review publication date, version, supported languages, and crawl timestamps.
Review the store description, core capabilities, and common use cases.
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.
Inspect the latest comments and rating distribution.
