I built a way to see exactly where an AI answer came from in a PDF

A developer has created a tool, available on GitHub as thesys-core, that allows users to pinpoint the exact source of an AI-generated answer within a PDF document. This project aims to enhance research by providing transparency for AI tools like Perplexity, ChatGPT, and Claude, which are often used to process large volumes of information. The developer announced this would likely be their final post about the project, expressing gratitude for community feedback.

This open-source tool offers a novel approach to AI transparency by allowing users to trace AI-generated answers directly to their source within PDFs, unlike other AI tools that only provide general citations.
