Anato vs Z-Anatomy

Anato combines USMLE question practice, study notes, and lessons built around a 3D anatomy model. Its question bank covers Step 1, Step 2 CK, and Step 3 with NBME-style clinical vignettes. Users can work through a question at a time or timed blocks, consult lab values, flag questions, and review explanations. Progress tracking records block scores, time, right and wrong answers, and accuracy by topic and exam step. In the 3D sandbox, users can switch body systems, reveal layers, select structures, and trace nerve and blood supply. Anatomy lesson cards use spaced repetition. Notes are arranged by exam step and subject, with key facts highlighted; gynecology and obstetrics are being written first, with other subjects in progress. An account works on the web, iPhone, and Android, with progress synced between devices. The Free plan uses energy limits and includes bones and muscles in the sandbox plus the first section of each notes book. Pro costs $9.99 a month or $59.99 a year, billed monthly or once a year, and unlocks all questions, notes, sandbox layers, and lessons.

Z-Anatomy is a free, open-source 3D atlas of human and veterinary anatomy built to run as a Blender template. The human atlas provides a navigable view inside Blender, using models derived from BodyParts3D and definitions that rely heavily on Wikipedia. To use the template, users need to download and install Blender, then install the template through Blender’s application-template command. A separate project repository contains models of non-human animals. The project also lists add-ons for cross-sections, labels, translation, visibility synchronization, and retrieving Wikipedia articles. Z-Wiki brings Wikipedia articles into Blender’s text editor, while Z-Translate can change languages and import or export translations of object names and data. Add-on compatibility varies: several list Blender 2.80+, while Z-Def, Z-Family, and Z-BONUS list Blender 4.5+. The code and content use Creative Commons Attribution-ShareAlike 4.0 International.
