The difference in one sentence, five questions for vendors and what the EU AI Act has required since August 2026. ## Key takeaways - An AI chatbot answers. An AI agent acts inside your systems. - Gartner: over 40 percent of agent projects end by late 2027. - Since 2 August 2026 every chatbot must identify itself as AI. - Document the process first, then decide on an agent. Since 2 August 2026, a chatbot in the EU has to disclose that it is not a human. In the same summer, almost every software vendor is selling you "agents". Both terms now appear on the same sales deck, and in many conversations they are used interchangeably. That is expensive, because they are two different products with two different risk profiles. Four in ten companies in Germany already use artificial intelligence. According to a [Bitkom survey from March 2026](https://www.bitkom.org/Presse/Presseinformation/Digitalisierung-der-Wirtschaft-Unternehmen-beschaeftigen-sich-mit-KI) of 604 companies with 20 or more employees, 41 percent use AI, compared with 17 percent a year earlier. Another 48 percent are planning or discussing it. For these companies the next question is no longer "AI or no AI", but this: is a chatbot enough, or do we need an agent? This article answers it in five minutes, with a decision rule and five questions for your next vendor call. ## The difference in one sentence An AI chatbot answers. An AI agent acts. An **AI chatbot** takes a question and returns an answer. Whatever happens next is done by a person. An **AI agent** takes a goal, breaks it into steps on its own, accesses your systems through interfaces, carries out the steps and checks the result. The chatbot tells you the invoice is overdue. The agent writes the reminder, books it and files the case. So the difference is not the language model. Both use the same technology. The difference is access: is the software allowed to change your systems or not? ## Three levels, not two camps In practice you will meet three levels, and the middle one is the one most often mislabelled. - **Level 1, the assistant.** ChatGPT or Copilot in a browser tab. An employee asks, rephrases, and copies the result onward by hand. No access to your systems and no access to your data, unless the employee pastes it in. - **Level 2, the chatbot.** Built into your website, customer portal or service desk. It knows your documents, your price list and your FAQ, and it answers in your name. It writes, but it does not act. Most of what is sold as an "agent" today is level 2. - **Level 3, the agent.** Access to ERP, CRM or mailbox, several steps in sequence, and its own decisions between those steps. Between level 2 and level 3, what changes is less the technology than the liability. A chatbot that answers wrongly produces a complaint. An agent that acts wrongly produces a record in your system that somebody has to reverse. ## Hype or leverage? What the reliable numbers say For agents, expectations currently run well ahead of results. [Gartner predicted in June 2025](https://www.gartner.com/en/newsroom/press-releases/2025-06-25-gartner-predicts-over-40-percent-of-agentic-ai-projects-will-be-canceled-by-end-of-2027) that over 40 percent of agentic AI projects will be cancelled by the end of 2027. The reasons given are not technical ones: rising costs, unclear business value and inadequate risk controls. On top of that comes a market problem Gartner calls "agent washing", meaning the rebranding of existing products such as assistants, RPA tools and chatbots without any real agentic capability. Of the several thousand vendors claiming agentic AI, Gartner considers only around 130 to be genuine. If this market looks confusing to you, that is not your fault. At the same time the direction is unambiguous. Gartner expects that by 2028 around 33 percent of enterprise software will contain agentic capabilities, up from less than one percent in 2024, and that 15 percent of day to day work decisions will be made autonomously, up from zero percent in 2024. Agents are coming, then, but not as a project you buy. They arrive as a feature inside software you already run. The gap between the front runners and everyone else shows up clearly among young companies. According to a [Bitkom survey from July 2026](https://www.bitkom.org/Presse/Presseinformation/Jedes-zweite-Startup-setzt-selbststaendige-KI-Agenten-ein), 48 percent of the startups surveyed already deploy autonomous AI agents. That survey of 102 tech startups is explicitly not representative, so it is no use as a market figure. As an indicator of direction it is very useful: companies starting without legacy systems are already at level 3, while most SMEs are still sorting out levels 1 and 2. **The verdict:** the chatbot is leverage today, with predictable effort and clear benefit. The agent is leverage in exactly one well defined, documented process, and still hype across the board. ## Five questions for your next vendor call These five questions separate a real agent from a rebranded chatbot. Ask them before you talk about price. 1. **Which systems is the software allowed to write to?** If the answer is "none", you are buying a chatbot. That can be the right choice, but it should then be priced like one. 2. **How many steps does it complete without checking back?** One step is an answer. From three steps with its own decisions in between, we are talking about an agent. 3. **What happens when a step fails?** Does the system notice by itself that something went wrong and correct course, or does it simply carry on? 4. **Where is the approval threshold?** At what amount, customer status or level of uncertainty does the system ask a human? If no such threshold exists, the risk control is missing, and that is what a large share of projects fail on according to Gartner. 5. **What ends up in the log?** You need to be able to reconstruct which decision was taken when and on what data. Without a log, an agent is indefensible in a dispute. Reliable market prices for AI agents among German SMEs do not exist yet, because the market is too young and too inconsistent. What can be said is that the licence is rarely the cost driver. The money goes into connecting your systems, preparing your data and reworking the output. We break down how consulting and implementation costs are put together in our article on [what an AI consultant costs](https://dieaiberater.de/en/blog/what-does-ai-consultant-cost). ## Since 2 August 2026: what the EU AI Act requires of both Article 50 of the [AI Regulation (EU) 2024/1689](https://eur-lex.europa.eu/eli/reg/2024/1689/oj/eng) has applied since 2 August 2026. It requires that AI systems intended to interact directly with people are designed so that the person concerned is aware they are communicating with an AI, at the latest at the moment of first interaction. Cases where this is obvious to a reasonably well informed user are exempt. One point matters for planning. The Digital Omnibus postponed large parts of the high risk obligations in the summer of 2026, to December 2027 and August 2028. Article 50 is not covered by that postponement and has applied unchanged since 2 August 2026. Only the machine readable marking of synthetic content under Article 50(2) has a grace period until 2 December 2026 for systems already on the market. Fraunhofer Academy [summarised the transparency obligation at the end of July 2026](https://blog.academy.fraunhofer.de/blogbeitraege/transparenzpflicht/). Infringements of Article 50 carry fines of up to 15 million euros or 3 percent of worldwide annual turnover under Article 99(4), whichever is higher. In practice this means two things. Your chatbot needs one sentence, visible before the first answer. Your agent needs a log on top of that, because it does not only speak, it acts. The full roadmap to the regulation is in our article on the [EU AI Act 2026](https://dieaiberater.de/en/blog/eu-ai-act-2026-what-your-business-needs-to-know). ## The decision rule For an SME the choice comes down to three sentences. - **Take a chatbot** when many people ask the same questions and the answer already exists in your documents. Typical cases are customer service, order status, technical enquiries and HR questions. Our guide to [AI in customer service](https://dieaiberater.de/en/blog/ai-in-customer-service-guide-for-smes) shows what that looks like day to day. - **Take an agent** when a recurring process runs across several systems, follows clear rules and produces a measurable result. Typical cases are invoice checking, quoting from a template and keeping data in sync between two systems. - **Take neither** when the process is not documented. An agent automates your process exactly as it is. If the process is unclear, you are automating the confusion, only faster. The most common mistake is not the wrong technology. It is the wrong order. Process first, tool second. ## The first step On Monday morning, take the last 20 items from a mailbox your team works through every day. Sort them into two piles: closed with a single piece of information, and closed with work in at least two systems. The first pile is your chatbot case, the second is your agent case. If the second pile is small or highly inconsistent, your company is not ready for agents yet, and that is good news: you have just saved yourself one of the 40 percent. If you would rather not do that sorting alone, we can go through it together. In the AI potential check we walk through your processes, assign each case to one of the three levels and say plainly what pays off and what does not.

An AI agent is software that takes a goal, breaks it into steps on its own, accesses systems such as ERP, CRM or a mailbox through interfaces, carries out the steps and checks the result. The difference from a chatbot is not the language model but the access: an agent is allowed to change your systems. ### What is the difference between a chatbot and an AI agent? A chatbot answers, an agent acts. The chatbot takes a question and returns an answer, and a person does the work that follows. The agent carries out several steps itself and makes its own decisions in between. That also shifts the liability: a chatbot answering wrongly produces a complaint, while an agent acting wrongly produces a record somebody has to reverse. ### Is ChatGPT an AI agent? In standard browser use, no. There ChatGPT is an assistant: a person asks, and a person carries the result onward. A language model only becomes an agent once it is connected to your systems through interfaces, completes several steps without checking back and is allowed to change data. ### What does an AI agent cost? Reliable market prices for German SMEs do not exist yet, because the market is too young and too inconsistent. What can be said honestly is that the licence is rarely the cost driver. The effort goes into connecting existing systems, preparing data and reworking output. Ask vendors to quote those three items separately. ### Does a chatbot have to disclose that it is an AI? Yes. Article 50 of the AI Regulation (EU) 2024/1689 has applied since 2 August 2026 and requires that people are aware they are communicating with an AI system, at the latest at the moment of first interaction. Cases where this is obvious are exempt. Infringements can be fined up to 15 million euros or 3 percent of worldwide annual turnover under Article 99(4). --- This page as a web page: https://dieaiberater.de/en/blog/ai-chatbot-vs-ai-agent German version: https://dieaiberater.de/blog/ki-chatbot-vs-ki-agent All articles: https://dieaiberater.de/en/blog
