Frequently asked questions

What is the difference between a RAG chatbot and ChatGPT?
A RAG chatbot answers exclusively from your internal documents. Unlike ChatGPT, it doesn't generate out-of-context responses and every answer is traceable to its source. The result: no hallucinations on your business data.
Can I use these services while staying GDPR-compliant?
Yes. All integrations can be deployed with European hosting or on-premise, with no data transfer to US servers. I primarily work with Mistral AI and OVHcloud for use cases requiring strict GDPR compliance.
How long does a typical AI project take to deliver?
For a RAG chatbot or targeted automation, expect 2 to 4 weeks depending on complexity and source data quality. A data pipeline or SaaS MVP typically takes 4 to 8 weeks. A precise scoping call is done before any estimate.
I have limited internal data. Can I still benefit from an LLM?
Absolutely. Modern LLMs work very well with a few dozen well-structured documents. The data engineering phase can also help consolidate and enrich existing data, even when fragmented, before putting it to use.
How does a typical engagement work?
A scoping call (30 min) to understand your needs, a technical proposal and quote within 48h, iterative development with weekly check-ins, then delivery with documentation and knowledge transfer so your team is fully autonomous.
