I will build a custom rag ai chatbot for your documents
Hanzala Ahsan
About this gig
Need an AI chatbot that answers from your documents instead of producing unsupported responses?
I will build a custom retrieval-augmented generation (RAG) chatbot using your PDFs, reports, policies, knowledge base, website content, or other approved data sources.
Depending on your package, your solution can include:
Document processing and intelligent chunking
Embeddings and vector database setup
Semantic search and evidence retrieval
Source citations in chatbot answers
FastAPI backend or functional web interface
PostgreSQL/pgvector integration
Integration with an existing application
Source code and setup documentation
Retrieval testing and response-quality checks
My experience includes leading the development of a financial-intelligence RAG system covering 158,570 SEC filing chunks across approximately 190 companies. The system combined vector search, query decomposition, cross-encoder reranking, evidence selection, grounded generation, citations, and automated evaluation.
Please message me before ordering with your data type, approximate number of documents, preferred AI model, required integrations, and deployment needs.
Package document limits apply. Hosting, paid model APIs,

FAQ
What types of data can you use for the RAG chatbot?
I can work with PDFs, reports, policies, manuals, knowledge-base articles, website content, structured text, and approved database content. Please message me first if your files are scanned, unusually large, or contain complex tables.
Which AI models and vector databases can you use?
I can work with suitable hosted or open-source language models and vector stores such as PostgreSQL with pgvector. The final choice will depend on your accuracy, privacy, deployment, and budget requirements.
Will the chatbot provide citations?
Yes. The chatbot can return source references with its answers. Retrieval testing and grounded prompting reduce unsupported responses, although no AI system can honestly guarantee zero errors.
Can you integrate the chatbot into my existing application?
Yes, existing-application integration is included in the Premium package. Please message me before ordering so I can review your technology stack, authentication, API, and deployment requirements.
Are hosting and AI API charges included?
No. Hosting, cloud infrastructure, paid language-model APIs, databases, and other third-party services are separate unless explicitly included in a custom offer. I will explain expected external costs before implementation.
Will my documents and business information remain private?
Yes. Your files will be used only for the agreed project and will not be published or reused. Please identify any special confidentiality, data-retention, or deployment requirements before ordering.
