Boss Hub | AI (formerly DocGPT & ChatPDF➶) vs LightPDF

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.

LightPDF lets you upload PDFs, Word files, Excel spreadsheets, PowerPoint decks, and scanned documents, then ask questions and get cited answers back. The ChatPDF feature runs on GPT-4, supports multi-document chats, OCR for scanned files, and follow-up questions. You can upload a file up to 100 pages on the free web tier before upgrading.

Unlike standalone ChatPDF clones, LightPDF bundles document chat into a wider PDF toolkit with conversion, editing, e-signatures, and a dozen other AI tools like mind map creation, PDF translation, and presentation generation. One premium subscription covers Windows, Mac, Android, iOS, and the web app, with AI credits allocated monthly or as a one-time pool on the perpetual plan.

Researchers, students, and office workers use LightPDF to summarize contracts, extract tables from financial reports, and pull outlines from long readings. Business teams can also use it for document Q&A on proposals and compliance files. The company behind LightPDF has operated since 2015 and holds ISO/IEC 27001, ISO/IEC 27701, and GDPR certifications.
