RAG & Knowledge Retrieval in Tamil Nadu
Most RAG projects fail at retrieval, not generation, the model was fine, the right passage was never fetched. We benchmark retrieval separately, because that is where the accuracy actually lives.
Tamil Nadu runs on automotive and auto components, textiles and apparel, electronics manufacturing, healthcare and IT services, high-volume manufacturing alongside a dense hospital network, the two settings where document throughput and shop-floor vision systems pay back fastest. Where rag & knowledge retrieval earns its budget here usually follows directly from that mix.
We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong. We hand over with runbooks, tests and a team that knows how it works, not a dependency.

Questions
Do you cover all of Tamil Nadu?
Yes, all 31 districts and 2,026 PIN codes. Delivery is remote-first, so coverage is genuinely statewide rather than limited to the cities we happen to have offices in.
Which Tamil Nadu sectors do you work with most?
Across Tamil Nadu the economy leans towards automotive and auto components, textiles and apparel, electronics manufacturing, healthcare, IT services. High-volume manufacturing alongside a dense hospital network, the two settings where document throughput and shop-floor vision systems pay back fastest.
RAG or fine-tuning?
RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.
How accurate will it be?
We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.
Can it respect our existing permissions?
Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.
