A multi-tenant documentation & troubleshooting assistant

An enterprise assistant with retrieval-augmented answers, built for multi-tenant usage with scalable retrieval and persona / access patterns.

2025

Challenge

Enterprise documentation is large, fragmented, and access-controlled. Users want a direct answer with a source — not a search results page. Doing this across many tenants raises the stakes: answers must respect each tenant’s data boundaries and personas, and retrieval has to stay fast and grounded as the corpus grows.

Approach

We built a multi-tenant assistant on a retrieval-augmented architecture using LangGraph and LangChain, the OpenAI API, FastAPI, and TypeScript. Retrieval is the heart of the system: scalable indexing per tenant, persona and access patterns enforced where the data is fetched, and grounded answers that cite their sources.

System design

  • Retrieval-augmented generation with per-tenant indexing
  • Persona and access controls enforced inside the retrieval layer
  • LangGraph / LangChain orchestration over the OpenAI API
  • FastAPI + TypeScript service surface for product integration

What we delivered

  • A multi-tenant assistant for documentation and troubleshooting
  • Scalable retrieval with grounded, source-backed answers
  • Access and persona patterns suited to enterprise usage
  • An integration surface the product team could build on

Why it mattered

A knowledge assistant is only useful if it’s trustworthy and safe across tenants. By engineering retrieval, grounding, and access together, the assistant gives users direct, sourced answers — without leaking data or eroding confidence.
