BuySage

Instant AI buying verdict on Amazon & 40+ shopping sites: sentiment, pros & cons, fake-review detection, buying score.

Shop smarter, not longer. BuySage reads the reviews on the product page you're already viewing and gives you a clear, honest buying verdict in seconds, so you don't have to scroll through hundreds of reviews yourself. Click the AI handle on the right edge of any supported product page (or press Ctrl+Shift+Y) and a panel slides out with everything you need to decide: ★ AI BUYING SCORE (0–100) A single, honest score anchored to the product's real star rating — not inflated by review count. A mediocre product gets a mediocre score. ★ CLAIMS VS REVIEWS Checks the seller's own marketing claims against what real buyers actually say, and flags where they don't match. ★ REVIEW INTELLIGENCE Overall sentiment, the features customers love most, and the complaints that come up again and again — pulled straight from the actual reviews. ★ FAKE-REVIEW DETECTION Flags suspicious patterns (generic one-liners, repeated phrasing, review padding) so a shiny star rating doesn't fool you. ★ PROS & CONS + RECOMMENDATION A plain-English "buy if… / avoid if…" so you know whether it's right for YOU. ★ ASK ANYTHING (voice or text) "Is it worth the price?" "How's the battery?" "Are the reviews fake?" Ask in the panel and get an answer grounded in that product's reviews. ★ COMPARE ACROSS PAGES Pin products as you browse different listings, then see which one wins. HOW IT WORKS BuySage analyzes reviews right on your device — free, instant, and private. There are no accounts and no sign-up. An optional "Pro" mode (off by default) can route analysis to your own AI backend for deeper, LLM-written summaries. PRIVACY FIRST In its default free mode, nothing you do leaves your browser. No tracking, no analytics, no data sent to us. Your pinned products and history are stored only on your device. See our privacy policy for full details. THREE WAYS TO OPEN IT • The AI handle docked to the right edge of any supported product page (it only appears when a product is actually detected) • The keyboard shortcut Ctrl+Shift+Y (Cmd+Shift+Y on Mac) • The toolbar icon (also lets you paste reviews from anywhere) WORKS WHERE YOU SHOP BuySage runs automatically on product pages of more than 40 major shopping sites worldwide, including Amazon and leading Indian and international retailers. On any other store — a brand's own shop, for example — click the toolbar icon and choose "Analyze this page" to run it on demand, on that tab only. Note: BuySage is an independent tool and is not affiliated with, endorsed by, or sponsored by any retailer it supports. All trademarks belong to their respective owners. BuySage only reads the page you are viewing to help you understand it; it never changes a site's own content, places orders, or accesses anything outside supported product pages.
