PDF AI Tutor is a Replit project that makes reading long PDFs simple and fast. By using OpenAI API, it lets you upload a PDF, get a clear summary, and then chat with your document. Instead of spending hours reading, you can ask questions directly and get answers like you are learning from a private tutor.

I built this project to solve my own problem - learning faster from heavy study materials and guides. I wanted a tool that saves time and helps focus on what really matters inside a document.

Large files filled with complex information.

Slow manual reading and note-taking.

Hard to find the right section when you have questions.

PDF Upload & Processing Used Files API and OpenAI to handle document uploads and prepare them for analysis.

AI Summarization Created a feature that delivers short and clear summaries of long PDFs, so key ideas are easy to understand.

Chat with Documents (RAG) Added a system to ask direct questions about the file. The AI uses Retrieval-Augmented Generation (RAG) to provide accurate answers from the PDF itself.

Private Tutor Experience Combined all features into an interactive learning tool where the AI acts like a tutor for any PDF you upload.

Faster Learning: Get summaries in seconds instead of hours of reading.

Better Focus: Ask questions directly instead of searching through pages.

Practical for Study: Works as a private tutor for courses, guides, and research papers.

Reusable Tool: Can be applied to personal study, business documents, or team training.
