What does it do?

139 groups here, covering 19,557 tools that answered our check today. Each group is its own page.

What the thing actually does. Every other axis here describes a property — who it's for, what it plugs into, what it refuses to do. This one is the noun.

A tool only lands here if a reader put it here, never a keyword rule.
