AI Agents Split by Use Case

The agent hype cycle is maturing into specialization: the products that stick are the ones that own one job end to end, not the ones that only look smart in a demo.

• –Browser agents like OpenAI Operator and Claude Computer Use are strongest for ad hoc booking, form-filling, and desktop tasks, but they still feel brittle once you need monitoring or repeatability.
• –Always-on tools such as MuleRun and Lindy AI matter because persistence is the product: scheduled checks, inbox work, and recurring reports without babysitting.
• –CrewAI and LangGraph are the serious builder options, but they trade simplicity for control, which keeps them out of reach for most non-technical users.
• –The comment thread points to the next battleground: MCP-style tool servers and vertical workflows in finance, sales, and customer support, where structured APIs may beat screen-driving agents.
