Grades how trustworthy Amazon reviews look, and shows the evidence. Runs in your browser: no account, no tracking. Grades the reviews on Amazon products from A to F and shows what each grade is based on. Everything runs in your browser: no account needed, and no browsing data is sent anywhere. A lightweight alternative to Fakespot, which shut down in 2025. ■ What it checks • Many reviews posted in a short period • Many reviews with similar wording • Short 5★ reviews with no real detail • Mentions of free products, refunds or other incentives • Ratings piled up at 5★ with few in between • Unverified purchases, and very high ratings from very few reviews ■ Evidence Click a warning to highlight the reviews behind it. An adjusted rating shows the average without the suspicious reviews. ■ Search results Warnings also appear on search results. ■ Free and Pro Free: grades and evidence on product pages, search warnings, 2 deep scans a day Pro ($4.99, one-time payment): grades for every search result (sponsored included), unlimited deep scans Sites: amazon.com / amazon.co.uk / amazon.ca / amazon.com.au Languages: English, Español, Deutsch, Français, Português, 日本語, 한국어, 简体中文, 繁體中文 Grades are automated estimates of how trustworthy the reviews look. They do not rate the product or prove that any review is fake. ReviewSleuth is independent and not affiliated with Amazon.
