Grove

See how a small monthly habit grows into real money.

Grove is an offline compound-interest calculator that turns a starting amount, a monthly deposit, an expected return and a time horizon into a projected balance you can actually feel. A live area chart splits what you put in from the growth that compounding adds on top, with a money-multiple and one-click summary copy. Built end-to-end with AI, it runs entirely in your browser with no login, and the whole single-file source is downloadable to self-host or remix.
