Crucible.
29 simulations. One cockpit.

Twenty-nine simulations across STEM, humanities, healthcare, cybersecurity, and business — all inside a spacecraft cockpit with 6 degrees of freedom. WASD to fly. Mouse to look. An AI tutor that asks questions instead of giving answers. 7 cognitive dimensions measured on every interaction.
