Chat PDF AI Source Code | Chat with Any PDF Using ChatGPT API

The Chat PDF AI project enables users to interact with and ask questions about the contents of any PDF document using OpenAI's ChatGPT API. By integrating the ChatGPT model with PDF parsing capabilities, this solution allows users to upload PDF files and engage in natural language conversations about the document's content. Whether it's for research, legal analysis, or educational purposes, Chat PDF AI simplifies the way users can extract and understand information from their PDFs without having to read through the entire document manually.

Capabilities

• PDF File Upload: Users can upload PDF files directly through a user-friendly interface.
• Natural Language Interaction: Ask questions about the PDF content in plain language, and receive accurate responses based on the document.
• Contextual Understanding: The AI can keep track of conversation history, allowing for follow-up questions and contextual responses.
• Text Extraction: Efficiently parses the PDF to extract relevant information and convert it into a readable format for AI analysis.
• Support for Complex Queries: Handle a variety of question types, including summaries, detailed information retrieval, comparisons, and clarifications.
• Multilingual Support: Capable of processing PDF content in various languages depending on the input capabilities of the OpenAI API.
