infoAbout PDF.ai
PDF.ai is a document processing platform that lets users chat with PDFs and offers an API for parsing, extracting, and splitting documents. Users upload PDFs to ask questions, get summaries, and retrieve specific information through a conversational interface. The API provides three main functions: parsing documents into structured JSON with OCR and layout detection; extracting custom fields using AI-powered prompts; and intelligently splitting PDFs into defined sections. It runs on a single REST endpoint with responses typically under five seconds, requiring only an API key and file URL. The platform is accessible via a website, with a Chrome extension mentioned as a product offering, and integrates through its API for custom workflows. Pricing includes a free tier with 200 monthly credits for testing, with paid plans starting at $49 per month. Credits are consumed per API call. Files are deleted after processing, and the vendor describes security as enterprise-grade. The content notes use by students from Ivy League schools, though this is a vendor-reported claim.
