About this gig
Tired of chatbots that hallucinate and make things up about your business?
Most "AI chatbots" are just a wrapper around ChatGPT. Ask them anything specific about your company and they guess they've never seen your data.
I build the real thing: a RAG chatbot that reads your actual documents and answers only from them, with a source shown for every answer.
I'm an Applied AI Engineer behind Ask PERA a live government AI assistant with a mobile app 15,000+ people use to get answers from official documents. When accuracy matters, this is what I build.
What I'll build for you:
- A RAG chatbot trained on your data PDFs, docs, website, Notion, Drive, or SQL
- Source-cited answers you can verify
- A pipeline that ingests and updates your files
- Integration via website widget, WhatsApp, or API
- An admin panel to manage your documents
- Accuracy tuning to keep answers grounded
Tech:
Python, FastAPI, LangChain, OpenAI (GPT-4), Claude, Pinecone/FAISS/Qdrant, Next.js.
Real engineering not a no-code template.
Full source code handed over, plus support after delivery.
Message me before ordering tell me what you need and I'll tell you honestly what it takes. Free consultation.

FAQ
Can this chatbot work with my PDFs, documents, or website content?
Yes. I can build the chatbot around PDFs, text documents, website content, or internal knowledge base material depending on your use case.
Will the chatbot answer from my data instead of generic AI knowledge?
Yes. The goal of a RAG chatbot is to retrieve relevant context from your content before generating the response, which makes answers more grounded and useful.
Can you integrate it with my website or internal system?
Yes. Depending on the package and scope, I can support website integration, backend API workflows, or internal tool use cases.
What do you need from me before starting?
I need your documents, links, or knowledge base content, along with your main use case and any technical requirements such as platform, integration needs, or privacy constraints.
