RAG intelligent chatbots

What is it?

A RAG chatbot (Retrieval-Augmented Generation) is an AI assistant that answers exclusively from your internal documents. Unlike ChatGPT, it does not hallucinate: every answer is traceable to its source, with EU hosting available for full GDPR compliance.

How it works

1. 1

   Document audit

   Analysis of your existing sources (PDFs, knowledge bases, wikis) and scoping the assistant's coverage.

2. 2

   Indexing and vectorisation

   Chunking, cleaning and vectorising documents into a vector database (Qdrant) optimised for semantic search.

3. 3

   Assistant development

   Building the RAG chain (LangChain), the interface and any required integrations (Slack, web widget, internal API).

4. 4

   Deployment and handover

   Production deployment on your infrastructure or EU cloud, technical documentation and knowledge transfer to your team.

5. 5

   Maintenance

   Onboarding support, source document updates and assistant adjustments based on your team's real usage feedback.

Frequently asked questions

What is a RAG chatbot?

▾

RAG stands for Retrieval-Augmented Generation. It connects a language model to a document base. Before answering, the model retrieves relevant passages from your documents and builds its response from those extracts. The result: no hallucinations, every answer is sourced.

What is the difference between a RAG chatbot and ChatGPT?

▾

ChatGPT answers from its general training data. A RAG chatbot answers only from your documents. It cannot respond out of context, every answer cites its source, and the data stays under your control.

Can my RAG chatbot stay GDPR-compliant?

▾

Yes. The solution can be deployed with an open-source LLM (Mistral 7B, Llama 3) hosted on your infrastructure or a European VPS (OVHcloud, Scaleway). No data leaves the EU. For less sensitive use cases, Mistral AI (Paris) offers a GDPR-compliant API with a DPA.

What document types does a RAG chatbot support?

▾

PDF, Word, Excel, emails, Confluence wikis, Notion, databases, web pages: practically any source of structured or unstructured text. The document audit phase assesses the quality of your sources to optimise answer relevance.
