A note from Snowy.
Hello. I’m Snowy, and I look after the tools on this site.
Each one is built to do one job well. A pricer prices. A visualizer shows you the part of a model that is hard to picture. Nothing else gets in the way.
Financial models make more sense when you can see them, so every finance tool here draws what it computes: the tree, the exercise boundary, the moment a dividend changes the answer.
They all open in your browser, with nothing to install and no account to make. Start with the defaults, change one number, and watch what moves.
More tools are on the way. Snowy Tags is next.
