When does an AI agent stop feeling like just another tool?

AI agents are starting to feel different from normal tools.

A normal tool waits for you to click, search, write, organise, or move things around. An AI agent is supposed to understand the task, take steps, make decisions, and sometimes work across different apps.

That sounds powerful, but it also creates a new problem: trust.

If an agent needs too much checking, it becomes another thing to manage. If it acts too freely, it can feel risky. The useful middle ground is when it saves time but still keeps you in control.

For me, an AI agent starts feeling useful when it handles the boring steps without making me nervous about the important ones.
