What You Get:
- Clean, production-ready Python code

- Clear communication throughout
Why Me?

FAQ
What types of documents can the chatbot read?
I can build chatbots that work with PDFs, Word documents (.docx), and text files. For the Premium package, multiple documents and large collections are supported. Just let me know your use case before ordering!
Which AI model will you use?
I primarily use OpenAI (GPT-4) and Google Gemini. If you have a preferred model or want an open-source alternative, message me before ordering and we'll figure out the best fit.
Can the chatbot remember previous conversations?
Yes! Standard and Premium packages include conversation memory stored in PostgreSQL so the chatbot remembers context across sessions.
Will I own the source code?
Absolutely. You get full ownership of all source code, no subscriptions, no lock-in. The chatbot runs on your own API keys and infrastructure.
Can this connect to my existing website or app?
Yes — I deliver a FastAPI backend with clean API endpoints that connect to any frontend, React, Next.js, or any web or mobile app.
