PDF.ai is built on large language models that process and embed PDF content, enabling semantic search and retrieval-augmented generation (RAG) for accurate document Q&A. In addition to the chat interface, PDF.ai exposes a REST API that allows developers to programmatically parse, extract text, split, and analyze PDF files at scale. The API is designed for easy integration into existing applications and workflows.
