What to know

Momentum is an interactive anatomy education platform. At its heart is a 3D human body you can rotate, zoom, search and explore (free for everyone). A membership unlocks the full educational library behind each structure.

Yes. Rotating and zooming the body, panning, searching anatomy, switching between muscular, skeletal and nervous systems, and highlighting any structure are all free, always. When you select a structure you'll see its name and a short description at no cost. The in-depth educational content is what a membership unlocks.

Building and maintaining an evidence-based anatomy library (writing it, reviewing it, and keeping it accurate) is ongoing work. Memberships fund that work and let us keep the interactive atlas free for everyone.

The full article for every structure: origin and insertion, function, innervation, blood supply, clinical significance, pain patterns, exercises, related anatomy and associated conditions. Educational videos and AI-guided answers are planned and will be included as they're released.

Two plans. Personal is $9.99/month for individuals: an individual account with the complete educational library and basic wellness content. Professional is $29.99/month, built for trainers, physical therapists, chiropractors, physicians, athletic trainers, coaches and wellness providers, and the plan under which the team features are being built: multiple staff logins, organization workspace, shared collections, presentation mode and priority support. Every one is labelled “Coming Soon” and none is available yet, so today Professional unlocks the same library as Personal. The interactive 3D atlas is free for everyone, and you can cancel anytime.

Content is written against established anatomical references and carries an honest review status on every record. Everything is currently authored and awaiting clinical review. No record is marked 'verified' until it has final sign-off, and the badge on each structure tells you exactly where it stands. We would rather show our working than overstate it.

Students, patients, athletes, movement and healthcare professionals, and anyone curious about how their body works. It's designed to be understood without a medical background.

Yes. The library grows continuously as structures are authored and reviewed. Momentum is early: the interactive body already covers the whole figure, and the written depth behind it expands over time.

Momentum is pre-launch, so content is added continuously rather than on a fixed schedule. We'd rather ship reviewed content when it's ready than promise a cadence we can't keep.

Not yet. Videos are in production and will be part of Premium as they're released. We don't list content that doesn't exist; when videos are live, you'll see them here.

Yes. Any membership (Personal or Professional) can be canceled at any time from your account's billing portal. Your access continues to the end of the current billing period, and it does not renew after that.

That's on the roadmap: guided answers grounded in the same cited evidence behind the library, so you can ask a question and get an explanation that points back to real sources. It isn't available today, and we'll keep saying so until it is.
