Overview

PDFGPT is an AI tool that converts PDF files into an interactive chat interface for summarization, question answering, and translation. It was founded in 2023 by Mihir Kanzariya and is based in Ahmedabad, India, operating as a small, unfunded company.

Beyond chat and summarization, PDFGPT includes page-level management tools to merge, split, reorder, rotate, or delete pages, plus chart analysis and content rewriting features built into the same interface. The company reports more than 160,000 users and positions the tool as free to use with no sign-up required for core functions.

PDFGPT suits individuals who need occasional PDF summarization or chat without paying for a subscription tool. The product is free to use, automatically deletes uploaded files after processing, and does not publish a separate paid tier.
