Yes, I use it nearly every day to write posts and translate posts in other languages as I am a part of many international chat groups in Telegram and elsewhere (such as doing international support for my customers).
LLM's truly allow people to communicate in ways never before possible due to proper grammar and formatting as well as the proper use of "slang" and "local" terminology when speaking to different people.
When using a good model (such as Qwen3.5 or newer, GLM 4.7 or newer) you can usually get an accurate picture of what is being said and also reply in an effective manner. It just takes some actual thinking / deliberation on the part of the models, so you can definitely eat up tokens. For me I have local LLM hardware here so most of those tokens are processed locally since I use it so often, but the result is great.
