Frequently asked

Yes — every tool is free, browser-only, and needs no signup. Use them for homework, exams, or work, as often as you like.
Type a molecular formula (e.g. C10H14N2) to look up matching structures, a full equation with = to balance it, or just the reactants and AI predicts the products — then they're balanced and verified. It also draws 3D structures and exports images.
Yes. The sidebar collapses into a drawer on narrow screens, layouts stack vertically, and the 3D viewers accept rotate / pan / pinch-zoom gestures.
