Upload a lateral cephalogram, click the landmarks, and get a full Steiner analysis — SNA, SNB, ANB, mandibular plane, incisor angulation, and an automatic skeletal & dental diagnosis — calculated instantly and explained in plain language.
No image leaves your device — tracing and Steiner math run client-side.

Manual cephalometric tracing is slow: printing the radiograph, taping acetate paper over it, tracing each structure with a 0.3mm pencil, then measuring every angle with a protractor. This free cephalometric analysis tool moves that same workflow onto a lateral skull X-ray you upload, replacing the protractor with exact trigonometric calculation. Click the same 14 landmarks an orthodontist would mark by hand, and the underlying Steiner analysis — every angle from SNA to the interincisal angle — is computed automatically.
It's built for dental and orthodontic students learning to read a cephalogram, clinicians who want a fast second check on a manual tracing, and anyone curious what their own profile X-ray says about skeletal and dental relationships. Because everything runs locally in your browser, there's no account, no upload to a remote server, and no cost — making it a genuinely free online cephalometric analysis option rather than a trial gated behind a paywall.
