Free 3D Learning, Forever.

Why We Built This

Complex STEM concepts shouldn't be locked behind paywalls or buried in static textbooks. AP Physics, Calculus, and Chemistry are notoriously hard to visualize — static diagrams can't show how a projectile curves, how a spring oscillates, or how molecular geometry changes with electron pairs.

ShowMeClass transforms abstract concepts into tangible understanding through fully interactive 3D simulations. Students can manipulate variables in real-time, experiment with different scenarios, and build intuition that textbooks alone can't provide. Every visualization is aligned with AP Learning Objectives and designed to complement classroom instruction.

Learn at Your Own Pace

No account required. No credit card. No trial period that expires. Just open a visualization and start exploring. Download any simulation to run offline during study sessions. Embed them in your notes. Share them with classmates. The tools you need to succeed should be accessible to everyone, regardless of economic background.

Enhance Your Lessons

Every visualization is a standalone HTML file — no frameworks, no subscriptions, no IT approval needed. Embed them directly in Google Slides, Canvas, or Notion with a single iframe snippet. Download them for offline classroom use. Use them for demonstrations, homework assignments, or lab activities. Check out our teacher resources for lesson plans and integration guides.

Technology

Each 3D visualization is built with Three.js and compiled into a fully self-contained HTML file hosted on Cloudflare's global CDN. The main site is built with Next.js 15 and deployed on Cloudflare Pages — ensuring fast load times worldwide with zero egress costs. The site is monetized via Google AdSense to keep the lights on while remaining 100% free for users.

What We Cover

Our library focuses on the highest-yield AP exam topics based on CollegeBoard's published exam weighting data. Priority subjects include AP Physics 1 (including the new 2025 Fluids unit), AP Calculus AB/BC, AP Chemistry, and AP Statistics. Community requests drive the production queue — vote on what gets built next.

How We Stay Free

ShowMeClass is funded entirely by Google AdSense display advertising. We display a maximum of 3 non-intrusive ads per page, in compliance with Google's Better Ads Standards.
