GradeWise Comics is a decision-support tool for comic collectors. Log the books you own, pull in market values and rarity, and let the grading engine answer the question that actually costs money: is a raw copy worth more than the graded upside once you account for fees, condition uncertainty, and market risk?
What It Does
Portfolio & Valuation
Track your collection with purchase price and estimated grade, alongside current raw values and CGC price tiers.
Rarity Scoring
A 0–100 rarity index from print run, census population, age, variant ratio, and key significance.
Grading Decision Engine
Expected graded value, ROI, break-even grade, and a plain-English recommendation — with a Monte Carlo view of best- and worst-case profit.
Insights & Alerts
Portfolio analytics (value, P/L, ROI) plus alerts when a book you own moves in price or census.
