PDF.ai is an AI document assistant. You upload a PDF, ask questions in plain language and get answers based on its contents. That saves time compared with reading a long file line by line.
Beyond the web app, it offers a Chrome extension, AI agents, OCR and an API for developers, with limits that depend on your plan.
