Built for precision
Designed for intuition

We combined professional-grade numerical solvers with beautiful real-time rendering. No downloads required.

Mathematics Simulations

Explore abstract mathematical concepts through interactive 3D visualizations. From linear algebra and vector calculus to complex topologies, directly manipulate parameters and see instant geometric responses.

Real-Time Data Output

Monitor precise telemetry through live, interactive charts. Track dynamic variables like energy, velocity, and fields as the simulation runs to perform deep quantitative analysis.

Save & Share Labs

Instantly bookmark experimental setups to your personal profile. Generate unique shareable links to collaborate, allowing anyone to instantly load and continue your exact simulation state.

WebGPU Compute

Harness the full power of your local GPU through WebGPU compute shaders. Experience desktop-class performance for complex N-body systems and high-resolution field solvers entirely in your browser.

LaTeX-Grade Theory

Master the underlying physics with comprehensive theoretical context. Every simulation is paired with cleanly typeset KaTeX equations, real-world applications, and structured guided exercises.

Comprehensive Domains

Spanning across Classical Mechanics, Electromagnetism, Quantum Mechanics, General & Special Relativity, Plasma Physics, and more.
