AI agent

An AI agent is a software system based on a language model that plans and carries out tasks on its own by using tools and data sources — such as looking up information, filling in forms or suggesting appointments.

Unlike a simple chatbot that only answers, an agent can take intermediate steps: understand a question, retrieve relevant data, trigger an action and check the result.

Agents are useful where processes are clearly defined and results remain verifiable. Clear boundaries are essential: which data the agent may access, which actions it may take and where a human approves.

On circle.gmbh, the AI assistant Karl answers visitors’ questions and takes enquiries.

What to look out for

  • Choose a clearly defined use case where results are verifiable.
  • Define which data the agent may access and which actions it may take.
  • Require human approval for consequential actions — orders, customer emails, deletions.
  • Clarify data protection and data location from the start.
  • Log answers and actions and spot-check them regularly.

Common mistakes

  • The agent receives extensive permissions without defined boundaries.
  • Answers are passed on to customers unchecked.
  • Confidential company data is sent to external services without review.

Frequently asked questions

A chatbot answers questions. An AI agent can additionally take steps on its own — look up data, use tools, trigger actions and check the result.

For example to pre-qualify enquiries, answer recurring customer questions, search internal documents or prepare quotes — always with clear boundaries and human oversight.
