Iโve used Microsoft 365 Copilot at my company. Itโs unfortunately subpar, even when using OpenAIโs models. Asking the exact same question in both ChatGPT and Copilot with the same model yields inferior results in Copilot, which fails miserably at some of the simplest tasks. I also completely agree with others whoโve said that no matter how many places you integrate Copilot, if it sucks, nobody will use it. You can put it in Excel, Word, or Outlookโthey all look identical and work like trash.
