What have you tried? I personally have used it for writing tests (and ideas for tests), to explain some old convoluted legacy code, to generate easy-concept functions like rect/rect collisions, rect/curve collisions, turning an in memory tree into html text, etc. All things I could do in 5 to 10 minutes, but ChatGPT does it in 5 seconds.
I've also used it to generate the floorplan of several commercial buildings, the jobs needed to keep those buildings operating, people to fill those jobs with varying ages/names/appearances and the relationships between all these people (only here things started breaking down). All this as background for a game I'm developing, this task would have taken significantly more time for me to do manually.
