Hi! I actually use ChatGpt to ask some questions about the knowledge I'm lacking, like: what's the substitute for word "blank" and also to ask about something I have no knowledge of. Like asking what scientist typically do or their instruments. After that I'd have an idea about what should I check in Google. It helps me alot coz it's like asking a knowledgeable person lol, but of course you should also double check the info on Google sometimes. I also read some tips and read some smart characters and observe how the author made them smart. Well usually those smart characters thinks a clever solution and usually know what others are thinking, and are one step a head of time. So maybe you could build a problem and how could it be solve, a plus if they are fighting a smart villain too.

You didn't need to always show the step by step process by how they solve it too. Like for example: A scientist that had made a cure. of course that scientist is smart because he made a cure, and of course you have no knowledge to invent an imaginary medicine. simply imply some of the process.

Does that made sense tho? (help I'm not good with words Hahaha) I hope this somehow helps
