I will build an ai chatbot for your pdfs and documents with rag and citations


About this gig
Want your team or customers to ask questions and get answers straight from your PDFs, with the page they came from?
I build document chatbots (RAG) that answer from YOUR files, quote the source and say "I don't know" instead of making things up.
WHAT MAKES MINE DIFFERENT
- Understands tables and charts, not just plain text
- Hybrid search (keyword + semantic) with reranking for accurate answers
- Every answer cites the document and page
- Streaming answers, like ChatGPT
- Works with OpenAI, Gemini or a private local model
REAL PROOF
I built an agentic RAG system (FastAPI, LangGraph, Next.js) that parses PDFs into text, tables and figures, rewrites questions, retrieves with hybrid search, reranks, checks its own answer and retries if it is weak. It traces every step so you can see why it answered.

FAQ
Will it make up answers?
It answers only from your documents, shows citations and tells the user when the answer isn't in the files. Standard and Premium add reranking and self-checks.
Can it understand tables and images in PDFs?
Yes, in Standard and Premium. Tables are parsed so numbers are quoted exactly, and figures get AI descriptions so they can be searched.
Which AI model do you use?
OpenAI, Gemini, or an open-source model running locally. You can switch providers later with one setting.
Can I add new documents later?
Yes. Premium includes an admin panel for uploads. In other packages I give you a simple command to add files.
Can it be embedded on my website?
Yes. I can deliver it as a standalone web app or a chat widget for your site (ask for a custom offer).
