BrickGauge is an AI LEGO grading tool for sealed-box collectors and resellers. Snap six guided photos of any sealed LEGO set and get a six-axis condition report, damage heatmap, reseal flag, and a calibrated SEND / MAYBE / HOLD / SKIP verdict — before you pay the $25–$40 AFA / CGC slab fee.
Each axis is scored 0–10 with calibrated weights matched to the subgrades AFA, CGC, and WATA actually publish. The overall condition rolls up into the standard MINT (M) / NEAR-MINT (NM) / EXCELLENT (EX) / VERY GOOD (VG) collector vocabulary you’ll see on BrickEconomy and BrickLink.
Factory adhesive, sticker geometry, reseal artifacts, double-pass marks, mismatched paper fibers along the seam.
All four primary-face corners. Compression depth in mm, whitening at the fold, dents from shelf weight or stacking.
Eight perimeter edges. Whitening, paper lift, color fade — the first defect a grader sees with the box flat on the table.
Six major faces. Dents, scratches, dust shadows, pressure marks, fingerprints burned into the print.
Print registration, ghost printing, UV fade. The silent killer — sun damage costs ~1 grade per 3 years on a shelf near a window.
Box geometry — squareness, paper lift, factory shrinkwrap state, box-flap alignment. Hard pass / fail at the bottom end.
Every inspection returns four artifacts: the headline 0–10 condition score, a defect heatmap with (x, y) coordinates per pin, per-image grades with each photo’s primary concern, and a clear verdict with predicted grade ranges at AFA, CGC, and WATA.
An AFA submission costs around $25–$40 and takes 3–6 weeks. If your box comes back AFA 80 instead of AFA 85, you’re out the fee, the wait, and now “graded 80” lives on its provenance — which can permanently hurt resale. BrickGauge tells you the answer in 38 seconds for $0 on your first two inspections.
Trusted by collectors on Whatnot, eBay, StockX, BrickLink, and BrickEconomy. Reports are shareable as a read-only public link or downloadable as a multi-page PDF.
You upload six guided photos (front, back, top seal, bottom seal, and two corners). BrickGauge's vision model scores six axes — seal integrity, corners, edges, surface, print, structural — and rolls them into a single 0–10 condition score plus a SEND / MAYBE / HOLD / SKIP verdict and likely AFA / CGC / WATA grade ranges. End-to-end in about 38 seconds.
Calibrated on 240,127 sealed sets, BrickGauge matches the published AFA / CGC grade within ±0.5 in 94.2% of cases and within ±1.0 in 99.1%. Reseal-detection recall against confirmed-resealed boxes is 97.4%. The remaining ~1% are typically MAYBE calls we flagged honestly, not over-confident misses.
Yes — that's the entire point of BrickGauge. Official AFA / CGC submissions cost $25–$40 and take 3–6 weeks. We tell you what the verdict will likely be before you ship, so you only spend the slab fee on boxes that earn it back. Save the money on the ones that wouldn't.
Seal integrity (factory adhesive, sticker geometry, reseal artifacts), all four front corners (compression in mm, whitening), eight edges (paper lift, edge wear, UV fade), the major faces (dents, scratches, dust shadows, pressure marks), print registration and color drift, plus overall box geometry (squareness, paper lift, shrinkwrap state).
No. BrickGauge is purely photo-based — you stay home, the box stays on your shelf. We're pre-grading intelligence, not a grading authority; the official grade still comes from AFA / CGC / WATA if you ultimately ship.
Two free inspections on signup, no credit card. After that, credit packs (10 / 50 / 200 credits) start at $29 and never expire, or a monthly subscription resets a credit pool each month (Starter $29, The Vault $79, Vault Elite $199).
Yes — adhesive bleed past the sticker boundary, double-pass marks, off-axis sticker placement, glue residue, and mismatched paper fibers along the seam are all flagged. When seal integrity drops below 5.0 / 10, the verdict softens regardless of how good the rest looks.
