PDF.ai

PDF.ai is a service for chatting with PDF files and a developer API for processing them. In the web app a user uploads a document, asks questions and receives answers and summaries, while the API parses PDFs into structured JSON, extracts custom fields and splits documents into sections. It serves students, professionals and developers building document workflows. The parse endpoint uses OCR and layout detection to return headings, paragraphs, tables and figures, field extraction works from custom prompts that pull out names, dates or amounts, and a separate ask endpoint lets code chat with documents. The vendor says files are deleted after processing. Other features include a Chrome extension, a chatbot widget for sites that host PDFs, a capture and ask screenshot tool, and AI Agents for document analysis, with availability varying by plan. The web app has four plans on annual billing. Hobby is free, with one upload, 100 questions per month and a 10MB file limit. Pro costs 10 dollars per month, Ultimate costs 20 dollars per user per month and Enterprise costs 30 dollars per user per month, with higher upload and question limits at each step. The API is priced separately: a free tier of 200 credits per month, then Starter at 49 dollars per month for 3,000 credits, Pro at 99 dollars for 10,000 credits and Scale at 249 dollars per month.
