Nutshell
By Nicky CaseA tiny tool for expandable explanations. Follow an idea without losing your place.
Tools and products
Useful tools, creator workflows and guides to turning a prototype into a usable product.
A useful tool removes a small piece of work for someone. That might mean making a calculation clearer, helping a reader follow an explanation or giving a creator a better way to build. Start by asking what a person can accomplish here that they could not do as easily before.
The projects in this collection include products and tools for making other work. Try the core action, inspect the original documentation and check whether the result is useful outside a prepared demo. The guides focus on the practical edges of a first launch: hosting, data, email, measurement and keeping an existing user’s work safe when you make a change.
