I used to write my emails with ChatGPT's help for a while, but looking back it's quite cringe because they're so obviously ChatGPT-written, even when I thought they weren't. Now I've given up on using AI assistants for emails completely, because I really don't want the same thing to happen again in retrospect.
Still beats my former boss having GPT write all sorts of important comms, including a "farewell message" for me when I left, using GPT. We could all tell but I don't think he realized it.
It’s basically not available in Europe at all. You can use it through Poe or through Kagi Ultimate. The API is available is Europe, so I don’t know why the Claude chat isn’t.
ChatGPT has a writing style that is recognizable. So, Claude outputs don’t seem as AI generated, but probably only because ChatGPT is more popular.
