The majority of my usage of ChatGPT as a dev has been to synthesize examples of APIs/tools/etc in usage when those aren't easy to find and/or when documentation is sparse/scarce.

Same to me so far, synthesise or summarise examples of tools I'm not familiar with to then explore the documentation.

Lately I've been using it quite a bit for Arduino on a ESP32 board, I had toyed around with Arduino previously but since I got this board for a small hobby project it's been great to ask ChatGPT to generate some examples of the kind of data I want to read from a few sensors. Even when it hallucinates something wrong it's been helpful for my learning.

Another way I've been using ChatGPT is to be a personal tutor to correct me when learning foreign languages, it's pretty easy to create a prompt asking ChatGPT to have a conversation with me in a given language while correcting any mistakes it believes I made, I've been getting feedback from these corrections from some native speakers and so far haven't got any case of "this is absurd and wrong", unsure why it works so well to correct my broken grammar but it does and without a fault.

I have noticed that there is a decent amount of regional (esp Salvadoran) slang that native Spanish speakers I know use that it doesn't recognize. This isn't a huge problem and it is still incredibly useful though, as learning a few random slang words isn't exactly a challenge.

As a supplier, I would be furious if one of my partners was sending AI emails to me.

I’m a software engineer and I use it everyday. I haven’t gone to StackOverflow in months. I use it like interactive documentation. I don’t even have to leave the terminal to use it as I have a cli tool called shell_gpt.
