Custom AI Apps & Chatbots

When your users need answers they can ask for.

As an AI chatbot development company we build the retrieval layer, not just the prompt. RAG-powered knowledge chatbots, branded conversational UIs, and custom LLM applications — multi-tenant, production-grade, with citations users can actually check.

How we build

Custom AI Apps & Chatbots built on foundations that hold

What you get

  • RAG architecture done right — hybrid search (BM25 + vector), reranking, citations, no hallucinated facts
  • Multi-tenant chat infrastructure with auth, rate limits, and per-tenant knowledge isolation
  • Embedded chat UIs that match your brand — Vercel AI SDK, assistant-ui, or fully custom
  • Eval suite to catch drift before users do
  • Cost telemetry — you'll know what every conversation cost and why

When this is the right fit

Straight answers on where this service earns its cost — and where it does not.

  • Your users repeatedly ask the same questions your docs already answer
  • You have a knowledge base no one reads
  • Your support team is buried in tier-1 tickets

Got questions? We have answers.

  • It's a fine prototype. It's not a product. You can't multi-tenant it, brand it, embed it, version-control your prompts, run evals, or audit its outputs. We build the production version.
