Question 1

is it really free?

Accepted Answer

yes. our way to give back to the ortho community. no trial, no credit card, no limits.

Question 2

is my data safe?

Accepted Answer

images are stored encrypted, LGPD compliant. delete them anytime. nothing is shared with third parties. we use the data anonymously to train and improve the ai — the more radiographs go through the platform, the more accurate it gets.

Question 3

how accurate is the ai?

Accepted Answer

the cephalometric landmark detector is an HRNet-W32 trained on a global dataset (AARIZ + a Brazilian dataset). it reaches a mean radial error (MRE) of about 2.4 mm on skeletal landmarks in the validation set — comparable to the variability among experienced orthodontists annotating the same radiograph. error is lower on soft tissue landmarks (~1.8 mm). always review before making clinical decisions — the ai assists, it doesn't replace you.

curious how all of this was built?

if there's enough interest, we'll record an open class covering the architecture, model training, clinical decisions — everything.
