    AI PDF Chat & Document API

    PDF.ai (pdf.ai) is an AI document platform for chatting with PDFs and processing documents via API. Users upload files, ask questions, and get cited answers; developers use REST endpoints to parse PDFs into structured JSON, extract custom fields, and split documents intelligently. It serves both end users and engineering teams building document workflows.
