Why an AI chatbot costs more than a scripted bot
A scripted bot follows fixed buttons and flows — cheap and predictable. An AI chatbot understands free-text questions and answers from your knowledge base. That extra value comes from real work:
- Data preparation. Your FAQ, prices, policies and docs have to be cleaned and structured so the bot can use them.
- Grounding (RAG). Retrieval keeps answers tied to your content instead of the model's imagination.
- Anti-hallucination guardrails. When the answer isn't in your data, the bot must hand off to a human — not guess.
- Multilingual handling. Answering each customer in their own language.
- Testing. Running real questions through it to catch wrong or unsafe answers before launch.
Ongoing costs
- Hosting: roughly €3–€10/month.
- AI model usage: if the bot uses a paid LLM API, you pay per message — usually a fraction of a cent to a few cents each. Built on local or open models, per-message cost is near-zero.
For a small business, picking the right model is often the difference between a chatbot that costs cents a month and one that costs hundreds.
How to avoid overpaying
- Start with a tight knowledge base. A focused bot on your top 30 questions beats a sprawling one that's never accurate.
- Insist on grounding + handoff. "Answers only from your data, hands off otherwise" should be non-negotiable.
- Ask about per-message cost up front. A local/open-model build can save a lot at volume.
- Own the result. Get the source and run it under your own accounts.
