ChatGPT has personalization settings that you can use to set part of the system prompt. Other chatbots usually have this too.
How much they follow it depends. Sometimes they know you wrote it and sometimes they don't. Claude in particular likes to complain to me its system prompt is poorly written, which it is.

That's not true, which field do you believe this to be? Because all of the fields I currently see in ChatGPT do have an effect on your conversations, but they're not just raw injections into system/developer prompts, it's something else.
Try using the API with proper system/developer prompts, then copy-paste that exact same thing into ChatGPT's "personalization settings" and try to have the same conversation, and you'll get direct evidence that it isn't actually the system prompts, but they're injected somewhere into the conversation.
