What is PDF.ai?

PDF.ai lets users upload PDFs, ask questions about their contents, request summaries, and find information through a chat interface. It combines document conversations with AI-powered OCR for reading scanned content. Paid plans increase upload and question allowances, while higher tiers add advanced AI models and team features.

For developers, PDF.ai provides APIs for document parsing, field extraction, splitting, and chat. Its parsing tools use OCR and layout detection to turn PDFs into structured data containing headings, paragraphs, tables, and figures. Custom prompts can extract specific fields, such as names, dates, and amounts, or identify sections to separate into individual documents. Developers can integrate these capabilities through REST endpoints using an API key.

The product is available through the web and a Chrome extension. A free Hobby plan supports one PDF upload and 100 monthly questions, with file-size and OCR limits that increase on paid plans.
