Instant, Cited Answers from Complex Documents
The USGA Rules Expert is a production RAG system that turns 200+ pages of rules into an AI assistant. Every answer cites the specific rule text it draws from. This is a live demo of the kind of system we build for clients.
Not Just Another Chatbot
Most AI chatbots hallucinate. They generate plausible-sounding answers with no source backing, and you have no way to verify whether the answer is correct.
The Rules Expert is different. Every answer includes the specific rule numbers and direct quotes that support it. Ask about a drop procedure and you'll see exactly which rule applies, what the penalty is, and the verbatim text from the 2023 Rules of Golf.
This isn't a prototype — it's a deployed production system handling real questions with rate limiting, streaming responses, interaction logging, and confidence scoring. It's the same architecture we use to build document intelligence systems for clients.
How It Works
Every question flows through a multi-stage pipeline designed for accuracy and transparency
Ask
User asks a natural language question about the rules. The system detects ambiguity and requests clarification when needed.
Retrieve
Vector search finds the most relevant passages across 469 document chunks, then a re-ranker selects the best matches.
Generate
Claude synthesizes a clear answer from the retrieved rule text, structured with applicable rules, penalties, and edge cases.
Cite
Every claim is backed by specific rule numbers and direct quotes. Nothing is asserted without a source.
By the Numbers
Technology Stack
Production-grade tools at every layer
Pinecone
Vector database with integrated inference embeddings (llama-text-embed-v2) for semantic search.
Claude (Anthropic)
LLM for answer generation with citation enforcement and structured output via streaming.
Next.js + Vercel
Full-stack framework with edge functions, streaming responses, and global CDN.
Vercel AI SDK v6
Streaming chat UI with real-time token delivery and structured message transport.
Upstash Redis
Serverless rate limiting (20/IP/day, 200 global/day) and interaction feedback storage.
Interaction Logging
Every question, answer, and user rating is logged for quality monitoring and continuous improvement.
What You Get
The same architecture powers expert assistants across industries. Golf rules are just the proof of concept.
Cited Answers, Not Guesses
Every response includes the specific rule numbers, section headers, and verbatim quotes that back the answer. Users can verify claims instantly.
Streaming Responses
Answers begin arriving in under a second via server-sent events. No waiting for the full response — users see tokens as they're generated.
Confidence Scoring
The system evaluates how well the retrieved context matches the question. When confidence is low, it says so instead of guessing.
Quality Feedback Loop
Thumbs up/down on every answer, with interaction logging that tracks question quality, retrieval relevance, and user satisfaction over time.
Built for Any Domain
Swap the source documents and the same system works for your industry
Legal & Regulatory
Turn dense legal codes, regulations, and compliance frameworks into instantly searchable, citable assistants.
Medical Guidelines
Help clinicians navigate clinical protocols, drug interactions, and treatment guidelines with source-backed answers.
Product Documentation
Convert technical manuals and API docs into interactive support agents that cite the exact page and section.
Financial Compliance
Navigate SOX, GDPR, PCI-DSS, and other frameworks with an AI that knows exactly which clause applies.
Technical Standards
Make ISO, NIST, IEEE, and other standards accessible through natural language queries with precise citations.
Internal Knowledge
Turn employee handbooks, SOPs, and institutional knowledge into a self-service expert your team can trust.
