Boss Hub | AI (formerly DocGPT & ChatPDF➶)
Boss Hub | AI is a Chrome extension sidebar for chatting with uploaded documents using ChatGPT and GPT-4. You upload a PDF, Markdown, Epub, or FB2 file, then ask questions, request summaries, and see highlighted source passages inside the side panel. It targets anyone who wants document Q&A without leaving the browser.
Compared with standalone ChatPDF sites, Boss Hub runs as a Chrome side panel and stores data locally on your machine. The listing highlights a built-in token usage tracker, periodic deletion of uploaded files, and support for Markdown alongside PDF. That local-first angle matters if you are comparing browser extensions rather than cloud-only upload tools.
Researchers, students, and office workers who already live in Chrome can use it to skim contracts, reports, or ebooks faster. The developer site is iambuffett.net, and the extension last updated to version 1.3.5 in July 2024.
