Chemistry tools that run in your browser. Everything runs locally with WebAssembly, so nothing gets uploaded anywhere.
HF and DFT with OCC, plus orbitals, geometry optimisations and frequencies.
Paste a 6×6 stiffness matrix and see how the moduli vary with direction.
Run an input script, plot the thermo output, watch the trajectory.
Play back optimisation paths and MD trajectories from multi-frame XYZ files, with unit cells.
Draw 2D structures from SMILES strings with RDKit.js.
Scroll through every molecule a SELFIES string can describe, each exactly once, or past that forever.
