If something shows up every week and usually starts from messy notes, it is probably a good fit for AI help.
A few good starting points
Meeting recaps, follow-up emails, weekly status updates, agenda drafts, blog outlines, client summaries, and simple SOPs are all strong first-use cases.
You do not need to overhaul your whole workflow
A small time-saving habit is enough. One repeated task handled better is often the beginning of everything else.
