About this gig

I will build an AI chatbot that answers questions from your own content (website, PDFs, docs, FAQs) instead of making things up.


What you can get:

  • A chat widget on your website, or a bot on WhatsApp or Telegram
  • Answers grounded in your documents (RAG), with sources
  • Lead capture: name, email and phone sent to your inbox or Google Sheet
  • AI agents that take actions: book appointments, update a CRM, call your APIs
  • OpenAI, Gemini, or a private local model if your data must stay in house


Why me: I build AI systems for a living, including a real time AI chat backend that streams responses to users and an offline AI desktop assistant with local LLMs and voice. You get a production quality bot, not a demo.


Every order includes a test period, and I will tune answers until the bot handles your real questions well.
