I never use LLMs for research or drafting. But I do use them to roll my own local semantic search; to whip up reusable regexes; to create small deterministic programs that, say, convert my set of paraphrased facts' citations to discrete documents into citations to the compiled appellate record; and to quickly code a Google Docs plugin that will automate away the repeated corrections to my co-counsel's bad typing and citation style (she'll never change).
For these uses, LLMs are wonderful — and Kagi Assistant is plenty good enough.
