I would draw a distinction here. If its a tool (as the GP proposed), it is just fancy auto complete. If it isn't a tool and is instead solving problems in novel ways, inventing new things, etc then it is intelligence and not a tool.

It can't be both in my opinion. To be a tool it needs to be controllable and predictable, intelligences are neither. See humans, and really all living things, for plenty of examples where they can't be completely controlled or predicted.
