Midpoint

Midpoint is an independent card centering measurement tool. It has no association with major grading agencies or card issuers, which means its output should be read as a pre-grading aid rather than an official verdict. You upload a photo of a card, and a machine-learning model finds the four card corners and the four corners of the printed frame in under a second. The tool then reports the centering ratio and the millimetre offset, and it gives grade estimates from PSA, BGS, CGC, and TAG. It also looks at the card surface, covering corners, printing, and holographic effects. Two analyses are free, and a weekly or semi-annual subscription unlocks unlimited use. It runs on iPhone, Android, and the web.

- Measure card centering from an ordinary phone photo in under a second.

- Get grade estimates from PSA, BGS, CGC, and TAG in one place.

- Upload a whole folder of card photos and work through them in sequence.

- Adjust the card by dragging, rotating, zooming, and panning for a cleaner read.

- Review surface details such as corners, printing, and holographic effects.

- Collectors who want to know which cards in a box are worth paying to have graded.

- Traders who need a fast quality read before agreeing on a price.

- Investors checking centering and estimated grade on a rare card before committing money.

The free allowance is only two analyses, so anyone working through a collection will need a weekly or semi-annual subscription, and the terms can change. The numbers are independent estimates rather than official grades, so an agency such as PSA or BGS may return a different result on the same card, and submission fees are still worth paying only when the estimate is strong. Photo quality, angle, and lighting still influence accuracy even though the tool tolerates poor shots. The surface review is a guide, not a full professional inspection, so use it to filter cards rather than to guarantee a final grade.
