About Hades

Hades brings useful websites together for learning, creative work, everyday tasks and exploring the web.

The name reflects the value that goes undiscovered: hidden talents, unused potential, and ideas left behind as regrets. Hades exists to bring some of those buried treasures into reach, connecting useful tools, knowledge and possibilities with the people who need them most.

Each subject is split into sections in a fixed order. A website listed in more than one subject appears once per view; select it to see every subject and section it belongs to.
