Compare prices, reviews and promotions across stores with on-device AI (Gemini Nano). No API key, data stays on your device. Shopping assistant that compares one product across the major online stores in Vietnam and the United States and tells you where to buy — without sending your data anywhere. The full list of supported stores is shown in the extension's Settings, where you can turn each one on or off. • Type a product name, or open any product page and click the floating "Find a better price" button. • Best overall / best price / best reviewed / best selling / best after-sales policy, with a plain-language verdict, pros & cons and buying tips. • Each listing shows the store's promotions (0% instalments, bank offers, gifts, fast delivery, free shipping). • Suspiciously cheap listings (used, grey import, counterfeit) are flagged, not hidden. • "Cheaper at other stores" card right on the product page you are viewing. • Save products, get a notification when the price drops, see the price history. • Coupon wallet: codes you see on store pages are remembered and can be tried at that store's checkout with one click — the extension only fills the promo field and presses "Apply"; it never places an order. • Ask the AI follow-up questions about the results. • Vietnamese and English interface, light / dark theme. Private by design: the AI is Gemini Nano built into Chrome and runs on your computer. There is no server, no account, no analytics. Searches go straight from your browser to the stores' public search pages, exactly like searching there yourself. AI features (verdict, review summary, chat) use Chrome's built-in Gemini Nano when it is available (Chrome 138+, ~2 GB one-time model download; the extension shows a one-click "Enable AI" step). Everything else — price comparison, ranking, promotions, price alerts, coupons — works on every Chrome without it, and verdicts fall back to built-in rules. Affiliate links are OFF by default. You can enter your own affiliate templates in Settings; when enabled, the footer says so and prices are unchanged. Prices are read live from the stores at search time and can change — always check on the store page before buying. Not affiliated with any of the stores. What's new in 1.2.0 • On-page card on the product pages of supported stores: "Compare now" fills in the other stores' prices right on the page. • Two more US stores, off by default: turn them on in Settings. • Prices in US dollars in the English interface; share a comparison as an image. • Used, refurbished and open-box items are labelled and never picked as "best price". • Fixed: the AI verdict could stay on "writing…" forever.
