A working reference of every known element. Search by name, symbol, or number — tap a tile to see its electron shells, mass, and a short story.
Look up a molecule by name to see its 2D structure, two kinds of interactive 3D model, alternate names, and computed properties — pulled live from PubChem.
Each group's 2D structure, what defines it, and which reactions in this app use it as a starting material or form it as a product. Tap any reaction chip to jump straight to that mechanism.
A browsable reference of core organic reaction types. Filter by mechanism family, search by name, tap a card for the full mechanism, conditions, kinetics, and stereochemistry.
Paste a SMILES string to render 2D/3D structures, detect functional groups, and suggest a reaction pathway using the same functional-group and reaction data as the tabs above. This tool is a separate, server-rendered page — it opens below in place, or in a new tab.
