About this gig
Most chatbots give generic answers because they're just raw ChatGPT with no configuration. That's not what I build.
I build custom, context-aware ChatGPT chatbots tuned to your business your tone, your knowledge, your rules. The bot stays on topic, remembers the full conversation, and pulls answers from your actual data not the open internet.
- GPT-4o with engineered system prompts for your use case
- Full multi-turn conversation memory per session
- RAG chatbot trained on your PDFs, docs, or website
- Streaming responses for a fast, real-time feel
- Secure backend API your OpenAI key never exposed
- Fallback logic so the bot never goes off-topic
- Chat history saved to database per user
- Clean, branded chat UI embeddable anywhere
- Works on any website, web app, or SaaS platform
Perfect for customer support, document Q&A, sales bots, internal helpdesks, and SaaS product assistants.
Tell me your use case and I'll recommend the right package.

FAQ
Will the chatbot actually know about my business or products?
Yes — that's the whole point. I engineer a custom system prompt that defines exactly what the bot knows, how it talks, what topics it covers, and what it avoids. For Premium orders, I also train it on your actual documents using RAG so it answers from your real data.
What's the difference between a regular chatbot and a RAG chatbot?
A regular chatbot answers based on the instructions in its system prompt. A RAG chatbot goes further — it reads your uploaded documents (PDFs, policy files, product docs) and retrieves the most relevant content before answering. The result is much more accurate and specific answers directly from you
Can the chatbot be added to my existing website?
Yes. I deliver an embeddable chat widget that works on any website — WordPress, Webflow, custom HTML, React, or any other platform. You just paste a script tag or component into your page.
