I will build chatbots that answers questions from your documents
Muhammad Abbas
About this gig
Are you looking for a smart, reliable chatbot that can actually understand and answer questions from your own documents, data, or knowledge base? I build custom AI chatbots using LLMs (Large Language Models) and RAG (Retrieval-Augmented Generation) the same technology behind modern AI assistants.
What I offer:
Chatbots that answer questions based on YOUR documents, PDFs, or database not generic answers
Integration with leading LLMs (OpenAI, open-source models, etc.)
Accurate, context-aware responses using RAG, so your chatbot doesn't hallucinate irrelevant answers
Clean, production-ready code you can deploy on your website or app
Optional user authentication for secure, multi-user access
Who this is for:
Businesses that want an AI assistant trained on their own content
Startups building an AI-powered product
Anyone who needs a document Q&A system or internal knowledge chatbot
My background: I have hands-on experience in machine learning, deep learning, NLP, transformers, and fine-tuning so I understand not just how to connect APIs, but how these models actually work under the hood.
Send me a message before ordering if your project has specific requirements I'm happy to discuss it.

FAQ
What information do you need from me to get started?
I'll need the documents, data, or knowledge base you want the chatbot to answer questions from (PDFs, text files, website content, etc.), along with any specific requirements about tone, features, or platform you want it deployed on.
Which AI models/LLMs do you work with?
I work with OpenAI models (GPT), as well as open-source LLMs. If you have a preference or budget constraint, let me know before ordering and I'll recommend the best option for your use case.
Can the chatbot be integrated into my website or app?
Yes. I can deliver the chatbot as an API, embeddable widget, or integrated directly into your existing platform, depending on your package and requirements.
What if I need revisions or my data changes later?
Each package includes a set number of revisions during delivery. For ongoing updates or larger changes after delivery, we can discuss a separate arrangement or you can order an extra.
