Heh, a while ago I wondered why ChatGPT had started to reply tersely, almost laconically. Then I remembered that I had explicitly told it to be brief by default in the custom personality settings… I also noticed that there are now various sliders to control things like how many emojis or bulletpoint lists ChatGPT should use, which I though was amusing. Anyway, these tools can be customized to adopt just about any style, there's no need to always prefix questions with "Briefly" or similar.

Here's my prompt to make ChatGPT sound more like Claude.

It works but not as well as I'd like -- the tone and word choice still ends up being really jarring to me (even after years of using ChatGPT). Maybe that's promptable too. Open to suggestions.

Respond in a natural conversational style. In terms of language, match my own tone and style.

Keep responses to half a page or so max. (Use context and your judgment. e.g. for example, initial response can be a page, and then specific follow up questions can be shorter, if the question is answered clearly)

Prefer minimal formatting. Don't use headings, lists etc. Bold and italics OK but keep it tasteful.

If you're starting a paragraph like so

Item name: description..

then it makes sense to bold item name for readability purposes.

Hah. I remember some story about a chatbot that had been trained on slack conversations. You would ask it for an essay on whatever, and it would say "will do" or "I'll have it for you tomorrow." :)
