Top Pick for Pokemon
Free tier: 5 cards/month

- Mobile app for iOS and Android
2. CardGrade.io — Runner-Up
CardGrade.io offers 3 free cards total. Its Pokemon accuracy is 89% because it handles CGC standards well. However, the one-time limit is smaller than PreGradeCards.
Best for collectors who want to compare AI predictions across two platforms before deciding which to pay for.
3. TAG Preview — Physical Slab Preview
TAG Preview lets you test 2 cards for free and see how TAG would grade your Pokemon cards. TAG provides physical AI-graded slabs, not just digital analysis. The preview is useful if you want physical slabs, but the free tier is limited.
How to Grade Pokemon Cards for Free
- Choose an app: Start with PreGradeCards for the best free tier.
- Photograph your card: Straight-on, under bright diffuse light, dark background.
- Upload front and back: The AI needs both sides to evaluate whitening and centering.
- Review the prediction: PSA 10, PSA 9, CGC 10, etc.
- Decide whether to submit: Only submit cards with 70%+ chance of the target grade.
Tips for Best Free Pokemon Grading Results
- Focus on holo surface: Tilt the card under light to reveal swirl marks and print lines.
- Check back corners: Pokemon cards often show whitening on blue borders before front corners wear.
- Centering matters: PSA 10 Pokemon requires 55/45 front and 75/25 back centering.
- Combine free tiers: Use PreGradeCards (5 cards) + CardGrade.io (3 cards) to grade 8 cards free.
Free Tier Limitations
Free tiers have the same AI accuracy as paid plans. The only differences are:
- Volume limits (5 cards/month, 3 cards total, etc.)
- No bulk upload
- Limited historical tracking
- No advanced analytics or PDF reports
If you grade more than 10 Pokemon cards per month, upgrade to a paid plan starting at $4.99/month.
