Question 1

How can I trust AI card centering analysis?

Accepted Answer

Our AI draws visible bounding boxes on your cards, showing exactly where it detected the card boundaries and inner frame. With 95% accuracy trained on thousands of professionally graded cards, our system matches human expert performance. Most importantly, you maintain full control with pixel-perfect manual adjustment capability.

Question 2

Can I manually adjust the AI detection?

Accepted Answer

Absolutely. Every detection can be manually refined with 1-pixel precision. You can adjust card boundaries, rotate for perspective correction, and fine-tune the inner frame detection. The symmetry calculations update in real-time as you make adjustments.

Question 3

How accurate is the AI card centering analysis?

Accepted Answer

Our computer vision system achieves 95% accuracy, trained on thousands of professionally graded cards from PSA, BGS, CGC, and ACE. We use advanced OpenCV edge detection, perspective transforms, and sub-pixel refinement to measure card symmetry within ±0.5% precision.

Question 4

Which grading standards are supported?

Accepted Answer

Centrifyx provides centering predictions for all major grading services: PSA (Professional Sports Authenticator), BGS (Beckett Grading Services), CGC (Certified Guaranty Company), and ACE Grading. Our system maps your card's symmetry measurements to all four standards simultaneously.

Question 5

Does this replace professional grading?

Accepted Answer

No, and it shouldn't. Centrifyx is a pre-check tool that helps you make informed decisions before spending money on professional grading submissions. Professional graders assess corners, edges, surface condition, and overall card quality - factors beyond just centering.

Question 6

How much does Centrifyx cost?

Accepted Answer

We offer a free tier with 10 analyses per month and 30-day data retention. Pro plan (£9.99/month) includes 100 analyses with permanent storage, and Business plan (£29.99/month) offers unlimited analyses. All tiers include the full feature set.

Question 7

What card types does Centrifyx support?

Accepted Answer

Currently optimised for Pokemon cards and sports cards (NBA, NFL, MLB, NHL). Our system works with standard trading card dimensions and frame styles. We're actively expanding support to Magic: The Gathering, Yu-Gi-Oh!, vintage cards, and special editions.

Question 8

How do shareable analysis links work?

Accepted Answer

Every analysis can generate a unique shareable URL that provides read-only access to the results. Perfect for sending to potential buyers or trading partners. Links remain active indefinitely until you disable sharing.

Question 9

Is my card data private and secure?

Accepted Answer

Yes. All analyses are private by default. We use Firebase Authentication and Firestore with strict security rules. Images are stored securely in Google Cloud Storage with encrypted transmission. We collect minimal personal data (email only) and comply with GDPR regulations.

Question 10

How does the eBay integration work?

Accepted Answer

Simply paste an eBay listing URL into Centrifyx. We use the official eBay Browse API to fetch all listing images, validate that it's a trading card category, and automatically process each image. No scraping, no privacy violations - just official API access.
