GRAILS Companion

QC photos, seller trust, the real cost with shipping and Discord ratings on Kakobuy, ZentBuy, Sugargoo and sellers’ Yupoo albums.

Check QC photos, convert links and check sellers before you buy. GRAILS adds QC photos, a seller trust score and the real cost with shipping to KakoBuy, ZentBuy and Sugargoo item pages, and to sellers' Yupoo albums. What you get: • QC photos for the exact item, without opening another tab • Link converter: any Weidian, Taobao or 1688 link to ZentBuy, KakoBuy, LitBuy and more agents • Seller check: trust score and ratings from real orders • Real cost: item plus shipping to your country, in your currency • Price drop alerts on items you save • Search 270,000+ finds from the toolbar • Quiet mode: closes KakoBuy's login popup • English, Polish, Spanish, German, Italian and Romanian Free. Made by grails.fit. GRAILS Companion adds the things reps shoppers actually check, directly onto Kakobuy product pages. It works on any listing, not a curated list of them. A home screen you will actually open. Click the GRAILS icon on any site, not just Kakobuy. One box searches the GRAILS catalogue (270,000+ pieces, real photos, prices in your currency) or turns a pasted Weidian, Taobao or 1688 link into a Kakobuy link and its QC photos. Below it: what GRAILS buyers are ordering today, refreshed every few hours. Seasonal drops. In October the panel goes Halloween: Spooky picks hand-chosen by the GRAILS team, a Trick or treat button that hands you a random piece, and the bag in a witch hat. December brings the Christmas version. On the seller's Yupoo too. Open any album on a seller's Yupoo and GRAILS puts one card under the header: the catalogue price, how many QC photos exist, whether the seller is vetted, what people on the GRAILS Discord rated them, and a Buy on KakoBuy button. Album grids get a small price badge on every album the catalogue knows, so you can see prices without opening each one. Sellers GRAILS has never heard of get nothing added. The numbers, on Kakobuy's own page. Above Kakobuy's Buy buttons, GRAILS adds the answers you would otherwise work out by hand: the price in your currency, the total once it is shipped to your country, how many QC photos exist, the seller's trust score, the parcel weight, and how many other agents carry the same item. Nothing to open, nothing to ask. All of it is worked out from the page and the GRAILS catalogue, not from an AI. Save the things you like. A heart on any Kakobuy listing keeps it, on the page and in the panel at the same time. The real payoff: one tap weighs everything you saved as a single parcel and prices it, which is the question you actually have. It also remembers what you paid attention to, so coming back to something you kept tells you whether the price has moved since. Every six hours the extension re-checks the catalogue price of everything you saved; when one gets cheaper, the number of drops shows on the toolbar icon and the saved list says what it was and what it is now. Seller ratings from real orders. People on the GRAILS Discord rate sellers they ordered from. The average, the count and the latest note show on the seller card, next to GRAILS' own trust score, with a link to add yours. It shops with you, and it remembers. The bag has a read on each listing ("this seller checks out, and there are 12 QC pics to look at"), notices when it is the third thing you have looked at from the same seller today, answers when you add something to the cart, and knows the difference between a seller it has history on and one it has never met. What it remembers stays on your machine and is never sent anywhere; one button in settings forgets all of it. It asks how much you have done before. First time, a few orders in, or you know the drill. That answer decides how much it explains, which tips it bothers you with, and how often it speaks at all. Change it any time in settings. New to buying through an agent? It walks you through the six steps of an agent order, from pasting a link to paying for shipping, and it marks the step you are standing on. The two that catch people out (the first payment is for the item only, and QC photos are the moment to speak up) are spelled out. A companion that talks while you browse. The bag drops what it finds as you go: what the item costs you landed, whether the seller is vetted, how many QC photos there are, and the occasional tip. Tap it and the same read continues as a conversation you can join, with the assistant at the end of the same thread rather than in a separate box. It speaks a few times per page at most, and one tap on the cross stops it for that page. The mascot, on the page. A small companion floats on every product page. Tap it and it reads the listing to you: seller trust, QC photos found, and what the item costs with shipping. The full details sit right below, no side panel needed (though there is one too). Weigh your whole haul, or your cart. On your Kakobuy cart, one tap weighs everything in it, using the real quantities, and prices the parcel landed. Not on the cart page? Paste rows from your haul spreadsheet instead. Either way each item is weighed from its real QC batch where one exists, the rest get an honest default, and the whole parcel is priced as one shipment. Every listing, in your currency. The item's title in English, its photo, its price in your own currency and what it costs landed, read from the page you are already on. QC photos. See quality-check photo batches for the exact item you're looking at, without opening another tab or pasting the link somewhere else. Seller trust. If the seller is in GRAILS' curated set, you get a score with the reasons behind it: community reputation, price/quality tier, how many of their products GRAILS catalogues, and curator notes. If they're not in the set, we say so plainly rather than inventing a rating. Shipping estimates. The parcel weight is picked up from the QC batch, and you get cost and transit estimates across MuleBuy, Sugargoo and Superbuy. What it actually costs you. The item price plus shipping to your country, in your currency, worked out from the QC batch weight, and always shown as both halves: what the item costs and what it costs to ship. That total is the number Kakobuy never puts in front of you. Buy via other agents. One-click links to the same product on other shopping agents. Ask GRAILS. An AI assistant grounded in the GRAILS catalogue, for questions about the item or seller. A quieter Kakobuy. Kakobuy throws a login popup over the listing and reminders you never asked for. GRAILS closes them as they appear, unlocks the page so it scrolls again, and tells you what it removed. A popup that follows your own click is always left alone, so logging in still works exactly as before. Optional extras: the promo banner above the header and the floating buttons. All of it is a switch away from being off. Dark theme for Kakobuy. An optional dark restyle of Kakobuy's own pages. Off by default, and reverts instantly when switched off. ### How this is funded (please read) This extension is free. On Kakobuy it applies GRAILS' own referral code only when you do not already have one, and GRAILS earns a commission on orders you place at no extra cost to you. You pay exactly the same price. It never replaces another creator's code. If you arrived through someone else's link, or a code from an earlier visit is already set, that code stays. The code is written into Kakobuy's own referral cookie. The links you click are never changed and nothing is added to the address bar. On Sugargoo and ZentBuy, the extension shows a "Use the GRAILS sign-up link" button on the sign-up page when you have no invite code yet. GRAILS' invite is only used if you tap it. This is how the extension is paid for. It can be turned off in the extension's advanced options, and everything else keeps working. ### What leaves your browser Only what's needed to answer your question: the product link (to look up QC photos and the seller), the parcel weight and destination country (to estimate shipping), and any question you type into the assistant. If you turn on "Help GRAILS grow" (off by default), the name and item link of sellers GRAILS does not know yet are sent too, once per seller. No account data, no browsing history, no analytics on you.
