What does PDF.ai do?

PDF.ai is a tool that lets you interact with PDF documents using artificial intelligence. You can upload a PDF and have a conversation with it, asking questions about the content and getting answers directly from the text. Beyond just chatting, it can parse entire documents into clean, structured JSON data, identifying elements like headings, paragraphs, and tables. It also has powerful extraction features to pull out specific pieces of information, such as names, dates, or monetary amounts, based on your custom queries.

The tool works through a straightforward web interface where you upload a file and start asking questions. For developers, it offers a comprehensive REST API, allowing you to integrate these AI document processing capabilities directly into your own applications. The API includes endpoints for parsing, extracting, splitting, and chatting with documents. It uses advanced OCR and layout recognition to handle complex documents, and processing is fast and scalable.

This tool is particularly useful for developers building automated workflows, business analysts who need to process many documents quickly, and students or researchers who want to digest long papers. Real-world uses include automating data entry from invoices, analyzing legal contracts, and quickly summarizing academic articles. The free plan offers 200 credits per month to try it out.
