RAG Systems & AI Chatbot Development

A chatbot that hallucinates is a liability. We build assistants grounded in your documents, with citations to prove it.

Retrieval-augmented generation (RAG) is the architecture that makes AI chatbots trustworthy: instead of answering from the model's general training, the system first retrieves the relevant passages from your documents — manuals, contracts, knowledge bases, tickets — and instructs the model to answer from that evidence, with citations.

Building RAG that works in production is a data engineering problem more than a model problem. Answer quality is decided by ingestion and chunking strategy, embedding and index choice, retrieval tuning, and reranking — long before the LLM writes a word. It's exactly where naive implementations fail and where we spend our engineering effort.

The same foundation powers document intelligence beyond chat: extraction, classification, and summarization pipelines that turn unstructured files into structured, searchable data your business can act on.

RAG (retrieval-augmented generation) systems ground AI chatbot answers in an organization's own documents using vector search and citations. ORVINUS builds production RAG chatbots and document intelligence systems including ingestion pipelines, permission-aware retrieval, extraction with confidence scoring, and measured answer-quality evaluation.

Capability 01

Retrieval-Augmented Chatbots on Your Knowledge

We build the full RAG pipeline: document ingestion with format-aware parsing (PDF, DOCX, HTML, tickets, databases), chunking strategies tuned to your content's structure, embedding generation, and vector search with reranking so the model always receives the best evidence available.

The chat layer on top handles what real deployments need: conversation memory, source citations users can click, confidence thresholds with honest 'I don't know' behavior instead of guessing, permission-aware retrieval so users only see answers from documents they can access, and feedback capture that turns usage into an improvement dataset.

Format-aware ingestion for PDFs, Office docs, HTML, and databases
Chunking and embedding strategy tuned on your corpus, not defaults
Vector search with reranking (Pinecone, pgvector) for retrieval precision
Cited answers with clickable sources and honest refusal on low confidence
Permission-aware retrieval respecting your access control
Measured answer-quality evaluation before and after every change
Capability 02

Document Intelligence Systems

Document intelligence turns files into data: extracting fields from invoices and contracts, classifying incoming documents, summarizing reports, and validating that extracted values make sense before they enter your systems. We built exactly this for doorlist.ai's real-estate document processing.

Pipelines are engineered for accuracy you can audit: extraction confidence scores, human-review queues for low-confidence cases, and structured outputs that flow directly into your database or workflow — not another folder of PDFs.

Field extraction from contracts, invoices, and forms with confidence scoring
Automatic document classification and routing
Summarization pipelines for long reports and filings
Human-in-the-loop review queues for low-confidence extractions
Structured output straight into your database, CRM, or workflow
Audit trails linking every extracted value to its source passage

FAQ

Common Questions

How is RAG different from just using ChatGPT?

ChatGPT answers from general training data; a RAG system retrieves the relevant passages from your documents first and answers from that evidence with citations. That's the difference between plausible-sounding text and answers your team can act on.

How do you prevent the chatbot from making things up?

Grounding plus honesty engineering: retrieval supplies evidence, prompts constrain answers to that evidence, confidence thresholds trigger 'I don't know' responses instead of guesses, and evaluation suites measure factuality on your domain before and after every change.

Can the chatbot respect user permissions on documents?

Yes — permission-aware retrieval filters the search index by the requesting user's access rights, so answers only ever draw on documents that user is allowed to see. Critical for legal, HR, and multi-tenant deployments.

How much data do we need for a useful RAG system?

Less than teams expect — a few hundred well-chosen documents often outperform a sprawling unmaintained wiki. Discovery includes a corpus audit; quality and structure of sources matter far more than raw volume.
