About this service

Give your customers an AI support agent that knows your business inside out. I build retrieval-augmented (RAG) chatbots that pull from your real documents, so answers are accurate, sourced, and never made up.

  • Vector database setup (Pinecone, Supabase, or Chroma)
  • Ingestion of your docs, help center, PDFs, and tickets
  • RAG pipeline with source citations to prevent hallucination
  • Deployment as web widget, Slack, or API
  • Guardrails, tone control, and escalation rules

Why me? I specialize in grounded AI that cites its sources, so your support agent is trustworthy enough to put in front of real customers. I tune retrieval quality, not just plug in a template.

Send me your knowledge base size and where you want the agent to live, and I'll scope the build. Let's deflect tickets without sacrificing accuracy.
