AI chatbot trained on your own data (RAG)
A chatbot trained on your data answers from your FAQ, prices, policies and docs — not generic internet knowledge. The trick is RAG: it looks up the relevant parts of your data first, then answers from them. That "look it up first" step is what stops it making things up.

What RAG actually means (plain English)
RAG = retrieval-augmented generation. Before the AI writes an answer, it retrieves the most relevant pieces of your content and reads them, then generates the reply grounded in what it found. No magic — it's "look up the right passage, then answer from it," done in milliseconds.
Why it stops hallucinations
- Answers come from retrieved passages of your real data, not the model's memory.
- When the answer isn't in your data, a good bot says so and hands off to a human — it doesn't guess.
- You can trace every answer back to the source content it used.
Grounding plus an honest "I don't know, let me connect you" is exactly what separates a trustworthy bot from a risky one.
How it's built
- Collect your content. FAQ, prices, policies, product docs, common replies.
- Clean & structure it into a searchable knowledge base.
- Wire up retrieval so the bot finds the right passages per question.
- Add guardrails & handoff for anything outside the data.
- Test on real questions before launch, then embed it on your site or chat.
What data you need
Whatever customers ask about — it doesn't have to be perfect, cleaning it is part of the build. Starting with your top 30–50 questions is usually enough for a strong first version.
What it costs
| Scope | Typical 2026 price |
|---|---|
| Focused build on a clean knowledge base | €300–€600 |
| Larger, multilingual, with integrations | €600–€1,500 |
| Ongoing | Low hosting + per-message model (near-zero on local/open models) |
