One small but useful way for me, I have to give a speech a few times a year. Previously, it would take forever for me to write it since I find it hard to distill my ideas and organize my points. Now I write my speech, let chatgpt summarize and outline it and then I can rewrite it in no time. It's a small use but it saves me lots of time and improves what I have to say.
I use mix copilot and lm studio to get the information and summarize the content
