Downloadbro i was opening like 6 tabs every time i wanted to check a listing 😭 this just tells me what i'm looking at instantly. PSA, CGC, raw — it gets them all. huge time saver for eBay scrolling
i sell a lot of sealed stuff and the variation detection is genuinely impressive. it catches things that aren't even in the title. saves me from having to manually dig every single time
didn't expect it to work for comics and sealed games too but here we are lol. i collect a bunch of different stuff and it handles all of it. actually super versatile 👌
late night eBay browsing hits different with this on. used to have 10 tabs open trying to figure out what i was looking at. not anymore. just works in the background and tells me what i need to know
picked up a Beckett slab from a listing that didn't even mention Beckett in the title 👀 that's when i knew this thing actually works. been using it every flip since
flipping sealed is way less of a headache now. variations used to take forever to track down manually. this just surfaces them automatically while i browse 🔥
sellers leave out so much info lol. this fills in the blanks for me. i've been able to make faster decisions without second guessing myself as much. really cuts down the research time
simple concept but the execution is solid. blurry photos, bad titles, missing info — it still figures it out most of the time. that's genuinely hard to do and it just... does it
i don't have to stop and think "wait is this PSA or CGC" anymore lol. it's just right there. doesn't mess with my flow at all which is exactly what i wanted
runs quietly while you browse and just... catches stuff. caught a detail on a listing i totally would've glossed over. worth having on just for that 🙌
use it for graded games and sealed stuff too not just cards. speeds up research a lot when you're hopping between categories. didn't realize how much i needed it until i tried it
i go through a LOT of listings and this keeps up no problem. pulls up the important stuff without lagging or getting in the way. exactly what you want from a browser extension tbh 🚀
