You will get Ask Questions from Any PDF Using AI (LangChain + OpenAI)
Project details
I specialize in building intelligent, user-friendly PDF Q&A bots using LangChain, OpenAI GPT, and Python. What sets this project apart is its ability to let users converse naturally with any PDF document—whether it's a manual, contract, research paper, or product guide.
Unlike generic tools, this solution is custom-built, offering flexible tiers that range from a simple local bot to a fully branded, cloud-hosted chatbot with multi-PDF support and session memory. With a clean UI (Flask) and efficient backend logic, the bot is fast, secure, and tailored to your exact needs.
Plus, I include personal onboarding support to ensure you're confident using the product from day one.
