What's the most underrated use case for AI agents?

Everyone talks about coding assistants and chatbots. I'm more interested in the less obvious ways people are using AI agents in the real world. Some examples I've come across: • Automating phone calls • Invoice processing • Internal knowledge search • Meeting follow-ups • Customer onboarding • Equipment monitoring • Scheduling and dispatch • Document review What's one AI agent use case that made you think, "More businesses should be doing this"? It could be something you've built, something your team uses, or something you've seen in the wild. I'd love to hear real-world examples.
