I will build a custom ai agent and rag chatbot trained on your data


About this gig
Most 'AI chatbots' are a thin wrapper around ChatGPT that makes things up and can't actually do anything. I build agents that know your real content and take real actions.
I'm a senior engineer with 12+ years in production software. I build RAG chatbots and AI agents trained on your own data: your docs, site, help centre, product catalogue. Answers come from your business, not a guess. Built on GPT or Claude, with LangChain.
Depending on scope, your assistant can:
- Answer from your real content, with sources, not hallucinations
- Use tools: book, look up an order, update your CRM, take a payment
- Remember context, hand off to a human, and track what people ask
Deploy it where your customers already are: your website, WhatsApp or Telegram. You get guardrails so it stays on-topic, analytics so you can see what's working, and the source code.
Tell me what it needs to answer and which systems it should touch. I'll map out the build and what it costs, in plain terms.

FAQ
How is this different from a ChatGPT wrapper?
A wrapper guesses from general knowledge and makes things up. I build on RAG: the assistant answers from your actual content (docs, site, database) and can take real actions through your tools
What can it be trained on?
Your website, PDFs, help centre, product catalogue, Notion, a database, past tickets, almost any text source. Basic covers one source; Standard and Premium pull from several.
Where does it live?
Wherever your customers are: your website, WhatsApp, Telegram, or inside your app. Tell me the channel and I'll deploy it there.
Who pays for the OpenAI or Anthropic usage?
You do, on your own key. A support or FAQ bot usually runs $20-$150/month; a busy agent can reach $300-$500. I estimate your volume up front and pick a model that balances cost and quality. My fee is one-time and separate.
Will it make things up?
That's the main thing I engineer against. Answers are grounded in your content with sources, and Premium adds guardrails that keep it on-topic and hand off to a human when it's unsure.
Can it do more than answer questions?
Yes, that's the point of an agent. It can book appointments, look up or update orders, write to your CRM, take payments, and trigger workflows. Standard adds tools; Premium is the full multi-tool setup.
Do I own it?
Yes. You get the deployed assistant, the source code, and a handover so you or your team can run and extend it.
