I will build a custom ai rag chatbot for your documents


About this gig
I will build a custom AI RAG chatbot that can understand and answer questions from your documents.
Whether you need an AI assistant for company knowledge, technical documentation, manuals, policies, reports, or research files, I can build a solution tailored to your requirements.
What I can build:
- PDF, DOCX, TXT, PNG and JPG document processing
- OCR for scanned documents
- Semantic vector search
- BM25 + semantic hybrid search
- Cross-encoder reranking
- Source citations and grounded answers
- ChromaDB or FAISS
- Hugging Face and local/API LLM integration
- FastAPI backend
- Streamlit web interface
I use retrieval-augmented generation (RAG) to retrieve relevant information from your documents before generating answers, helping reduce unsupported responses and improving answer reliability.
You can use the system for:
- Company knowledge bases
- Customer support
- Technical documentation
- Internal document search
- Research collections
- Manuals and policies
I can build a simple prototype or a more advanced RAG application depending on your requirements.
Please contact me before ordering so I can understand your documents, expected features, and recommend the right solution.
