LLMs are not nice to use for spell checking. I do not want to read a wall of text from LLM just to find a missed article somewhere and I want to receive feedback as I type. Also, once I asked LLM to check the message. It said everything looked fine and made a copy of the message in its response with one sentence in the middle removed.
