I havily use llms for internal communication. I receive docen request per day from colleagues asking me very specific stuff by mail or teams about processes, setups, master data, my particular experiences with approaches, for contacts within our big corp or just general knowledge questions and how I would recommend to tackle certain problems: Setting up conditions in sap, where to find certain info or just send them current setups. Also they ask me about strategic advices. I use my personal knowledge base to automatically prepare drafts of the answers based on previous answers to other colleages. Before the llm time I could barely help all of then. I got more productive by x-times. I then digest the emails again back to my knowledge system. People have no problem with receiving obviously llm written answers. But because of the particular domain knowledge they know it can only come from me. Excuse my writing, this did not went though the same system :)

Edit: And now I forgot the most important. When the knowledge the llm retrieved is insufficient to answer colleagues question or the agent skill can not execute the requested task from my colleague, it asks me just for the missing info or skill and with me (the human) in the loop work is done x times faster. Eventually it will replace me and all my colleagues one day. Looking forward to do other stuff then
