For repetitive, rules-based work that needs to happen fast and around the clock, AI agents usually win. For judgement-heavy work, people do. Most teams end up with both: agents take the busywork, people take the decisions.
DIY tools make sense if you have an in-house technical team with time to build, test and maintain automations.
Start with one agent on your most repetitive task and keep your team on everything that needs a human. Measure the hours saved for 30 days, then decide what to do next.
