Models / Your kinetic model

Build your own kinetic model

Define your system as reactions with rate laws and stoichiometries.

Open Edit model to add variables, parameters, assignments, and reactions, then watch the simulation update live.

Every bar shares one fixed step budget. Drag a divider to move a cutoff, drag a bar's top edge (or focus it and use the arrow keys) to change its share — the final stage isn't draggable, it always gets whatever's left. Double-click a bar or use its + to split it, use a divider's × (or Delete/Backspace while it's focused) to remove it.
