I don't use it to avoid reading man pages. Rather, as often with LLMs, this is a faster way to do things I already know how to do. Looking at commands I run in various situations and typing them for me, faster than I can remember the name of a flag i use weekly with a pdf processing tool or type 5 consecutive shell commands.
Money wise, my full usage so far (including running purposely large inputs/outputs to stress test it) has cost me.... 19c. And I am not even using the cheapest model available. But, you could also run it with a local model.
