PDF.ai

Scrolling through a long PDF to find one answer wastes time. PDF.ai is an AI PDF chatbot that lets you ask questions about a document, summarize it and pull out specific information.

It also lists an API and quiz generation among its uses.

The free Hobby plan allows 1 PDF upload and 100 questions a month on gpt-3.5-turbo, so it suits a quick test more than regular work.

Pro is $10 a month billed yearly and raises the limits to 100 PDFs and 1,000 questions.

Ultimate is $20 per user a month, removes the limits and adds all GPT-4 models, Claude 3.5 Sonnet, AI Agents and Capture & Ask.

Enterprise is $30 per user a month and adds a white-labeled PDF embed, early access to new features and live chat support.
