Whether you’re researching, studying, or analyzing documents, PDF AI helps you extract insights faster and more efficiently.How It Works
PDF AI uses a sophisticated RAG (Retrieval-Augmented Generation) architecture:- Upload: Your PDF is uploaded to secure cloud storage
- Processing: The document is split into chunks and converted to vector embeddings
- Storage: Embeddings are stored in Pinecone vector database for fast retrieval
- Query: When you ask a question, we find the most relevant chunks
- Response: GPT-4 generates an accurate answer using the retrieved context
