Frequently Asked Questions

Get answers about AI card grading

How accurate is AI card grading compared to professional services?
Our AI card grading tool provides highly accurate pre-grade estimates by analyzing the same factors professional graders examine: corners, edges, surface, and centering. While AI grading cannot replace physical inspection and authentication from PSA, BGS, or SGC, our tool helps collectors identify gem mint candidates and avoid wasting money on cards that won't achieve high grades. Users report estimates typically fall within 1 grade of professional results.
What types of cards can the AI analyze?
Our sports card AI grading system works with all major card types including baseball, basketball, football, hockey, soccer, UFC, and Pokemon cards. We support both modern and vintage cards from manufacturers like Topps, Bowman, Panini, Upper Deck, Fleer, Donruss, and more. The AI adapts to different card stocks, finishes (chrome, prizm, refractor), and eras.
Is the mobile app better than the website?
The mobile apps provide the superior experience with native camera integration, push notifications, and optimized interfaces. Download HobbyMonitor from the App Store for iPhone/iPad or from Google Play for Android devices. While web access is available, serious collectors prefer the mobile apps for their advanced features and on-the-go functionality.
How does this compare to ChatGPT or Claude for card grading?
While you could upload card photos to ChatGPT Plus ($20/month) or Claude Pro ($20/month), HobbyMonitor offers a superior experience at a fraction of the cost. Our service is specifically designed for card collectors with specialized analysis, structured grading reports, and an interface built for card evaluation. Plus, you get additional tools like Market Pulse price analysis that general AI services don't provide.
What devices work best for card grading?
Any modern smartphone works great! iPhone users get the full native experience through our iOS app, while Android users enjoy optimized performance through our Google Play app. Both apps automatically adjust for your camera capabilities and provide guided photo capture. Even mid-range phones from the last 3-4 years deliver excellent results with good lighting.
Can AI detect fake or counterfeit cards?
While our AI can identify certain inconsistencies that may indicate counterfeits (unusual printing patterns, incorrect colors, suspicious wear patterns), it's not a replacement for professional authentication. The AI focuses primarily on condition assessment for legitimate cards. For high-value cards where authenticity is a concern, we recommend professional authentication services.
How many cards can I grade with the free plan?
Our free plan includes 2 AI card scans per month, perfect for trying the service. Premium members get 10 scans monthly ($0.60 each), while Pro members receive 30 scans ($0.43 each). This makes HobbyMonitor the most affordable card grading AI available compared to $5+ per scan from other services or $20/month for general AI tools.
What information does the grading report include?
Each AI card grading analysis provides: overall grade estimate (PSA scale), subgrades for corners, edges, surface, and centering, confidence percentage, specific condition notes and defects identified, comparison across PSA, BGS, and SGC standards, and recommendations for professional grading. Reports can be saved and shared.

AI Card Grading Technology

The Evolution of Card Grading: Traditional card grading has remained largely unchanged since the 1990s. Professional graders manually examine each card under magnification, a process that takes significant time. With the explosion in card collecting popularity, submission backlogs can stretch months, and grading costs continue to rise. AI card grading technology changes everything.

How It Works: HobbyMonitor's AI card grading tool uses advanced computer vision to analyze your cards. Our system examines corners, edges, surface quality, and centering using specialized algorithms designed specifically for sports card condition assessment to provide PSA-style grade estimates.

Corner Analysis: The AI examines all four corners at high resolution, detecting issues invisible to the naked eye. It identifies soft corners, dinged corners, bent corners, and fraying, understanding the difference between a slightly touched corner that might grade PSA 9 versus a pristine corner worthy of PSA 10.

Edge Detection: Our mobile card grading app analyzes all four edges for chipping, roughness, or damage. The AI distinguishes between factory-fresh edges and those showing wear from handling, even detecting edge issues hidden by certain angles or lighting conditions.

Surface Evaluation: Perhaps the most complex aspect of card grading, surface analysis requires detecting scratches, print defects, staining, creases, and other issues. Our AI uses multiple analysis passes to identify surface problems that might be missed in a quick visual inspection.

Centering Measurement: The AI precisely measures borders to calculate centering ratios, accounting for different card designs and automatically adjusting for vintage cards where perfect centering is rare. The system provides exact percentages (e.g., 55/45 left-right, 52/48 top-bottom) crucial for high-grade determinations.

Why Mobile Card Grading Is the Future: The ability to grade cards instantly using just your phone camera revolutionizes collecting. At card shows, you can evaluate potential purchases on the spot. When organizing your collection, quickly identify your best cards without handling them repeatedly. Our mobile card grading app puts professional-level analysis in your pocket.

Beyond Basic Grading: HobbyMonitor's AI doesn't just provide a number. It offers insights that help you understand your card's condition, explains why a card received a particular grade, identifies specific issues, and suggests whether professional grading is worthwhile based on the card's value and condition.

Integration with Market Data: Unlike standalone card grading AI tools, HobbyMonitor combines condition analysis with real-time market data. After grading your card, instantly see what similar cards in that grade are selling for. This integration helps you make informed decisions about selling, grading, or holding your cards.
