I will build an ai chatbot on your documents with rag and source


About this gig
Generic chatbots guess. A RAG system answers from YOUR documents manuals, contracts, wikis, price lists and cites the source for every answer, so your team can trust it.
I build and run RAG systems in production: a document-intelligence assistant that a family business uses daily over thousands of scanned records, and a technical-manual assistant for machinery sales. I know where RAG fails in practice messy PDFs, tables, confident wrong answers and I build against exactly that.
What you get:
A chatbot that answers from your documents, with source citations on every answer
Hybrid retrieval (vector + keyword) not the naive setup that misses exact terms
Honest evaluation: we test with YOUR real questions before handover
Deployment to your infrastructure (your accounts, no lock-in) + documentation
Works with PDFs, Office files, websites, databases. German and English documents are both first-class ideal for DACH businesses.
Not sure if RAG fits your case? Message me with what you want the bot to answer and I'll scope it honestly including when a simpler search would do.

FAQ
Where does my data live?
In your accounts (e.g. your own Supabase/Postgres and AI API keys). I build in your infrastructure; nothing stays on my side. AVV/DPA for German businesses on request.
Which AI model does it use?
Your choice and your API key. EU-hosted models are possible if data residency matters.
Will it hallucinate?
RAG reduces but doesn't eliminate wrong answers. That's why every answer cites sources and we evaluate with your real questions before handover. I'll tell you honestly what accuracy to expect for your documents.
Scanned PDFs, tables, mixed quality?
That's most of what my production systems ingest. Send 2–3 sample documents before ordering and I'll confirm feasibility.
