RAG & Knowledge Retrieval in Bihar
A RAG system that cannot cite its source is a liability. Every answer we ship points back to the page it came from, so a reader can verify in one click.
Bihar runs on agriculture, food processing, education and retail and distribution, distribution networks and public service delivery across a very large rural base. Where rag & knowledge retrieval earns its budget here usually follows directly from that mix.
We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep. Six weeks to something running in production, not six quarters to a strategy document.

Other capabilities across Bihar
Questions
Do you cover all of Bihar?
Yes, all 38 districts and 862 PIN codes. Delivery is remote-first, so coverage is genuinely statewide rather than limited to the cities we happen to have offices in.
Which Bihar sectors do you work with most?
Across Bihar the economy leans towards agriculture, food processing, education, retail and distribution. Distribution networks and public service delivery across a very large rural base.
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.
