An AI service desk agent is AI software that answers employees' questions about IT and HR in a chat window, and also acts in the company's systems to solve the request. For example, it can reset a password, grant access to an application or look up a leave balance. It is also called an employee support agent, an IT and HR assistant or an AI help desk agent. When it cannot solve a request, it raises a ticket for a person.
An older chatbot could only answer from a fixed list of questions. The agent works differently. It uses a large language model (LLM) to understand what the employee has written, in ordinary words. It finds answers in the company's own policies through enterprise search. And it has tools. A tool is a connection that lets the agent take a specific action in another system, such as "unlock this account".
Say a warehouse supervisor at a logistics company in Gurugram is locked out of her account at 7:40 a.m., before the IT team arrives. She opens the company chat on her phone and types, "I'm locked out." First, the agent confirms that she really is the supervisor. It sends a prompt to her registered phone, which she approves. This is multi-factor authentication (MFA). Then the agent unlocks her account and sets a temporary password. This takes two minutes. Next, she asks how many days of leave she has left. The agent reads her record in the HR system and replies: nine days of earned leave. Then she asks for access to the new route-planning application. That access needs her manager's approval. So the agent sends the request through identity governance (IGA), which asks her manager. Finally, she reports that the screen of her handheld scanner is cracked. The agent cannot fix hardware. It raises a ticket in the ITSM software, with her name, the scanner's number and the problem already filled in.
The IT department is often the first department in a company to let an AI agent act on its systems. One reason is that a large share of IT tickets are the same few requests. Another reason is that IT staff built these systems, so they know exactly which actions are safe.
An agent that can change accounts must itself be controlled. It needs its own login, only the permissions its job requires, and a record of every action it takes. This is the work of AI agent identity and security, and it follows the rule of least privilege. The agent must also reset the password only of the person it has verified, never of someone else.
The same idea is used for customers. An AI customer service agent chats with a company's customers and acts on their orders. The AI service desk agent does this for the company's own employees. Some HR versions also run short surveys in the same chat, and they report which questions employees ask most often.
