Grade.IQ uses advanced AI to analyse your Pokémon cards and estimate professional grades before you submit — saving you time and money. PHOTO-BASED GRADING Simply photograph your card and our AI analyses centring, corners, edges, and surface condition to give you an estimated grade in seconds. MULTIPLE GRADING STANDARDS Get estimated grades for PSA, Beckett (BGS), ACE Grading, CGC, and TAG — built around each company's published standards, all in one scan. CLAHE ENHANCEMENT FILTERS Grade.IQ doesn't just look at your photo. It applies professional CLAHE imaging filters (adaptive histogram equalisation) to reveal micro-scratches, edge whitening, and surface texture invisible to the naked eye — for a sharper, more accurate grade. REAL MARKET VALUES See actual eBay sold prices for graded copies of your card, so you know exactly what it's worth at every grade level — and which company gives you the best return. TCG ADVISOR Chat with your own AI card expert for instant answers on values, grades, deals, and whether a card is worth submitting. DEEP GRADE MODE Capture up to 16 photos including close-ups of all 4 corners for the most accurate AI assessment possible. BULK GRADING Grade up to 20 cards at once — perfect for sorting through a collection quickly. CROSSOVER GRADING Already own a graded slab? Estimate how it could score with a different grading company before you cross it over. JAPANESE CARD SUPPORT Full support for Japanese sets with Cardmarket EU pricing. Whether you're a collector, trader, or serious grader, Grade.IQ gives you the edge before your cards go in the post. BUILT BY THE COMMUNITY, FOR THE COMMUNITY I'm a solo developer and a collector just like you — and this is the very first app I've ever built. I made Grade.IQ for our community because it's something I wanted myself. As a one-person team you may run into the odd bug, but I'm fully committed to fixing them quickly and making the app better with every update. Your feedback means everything — thank you for giving Grade.IQ a try.
