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

PDF AI lets you upload a PDF and ask questions in plain language, with cited answers pulled from the document text. The web app handles chat across books, legal contracts, financial reports, and research papers, while a Chrome extension adds the same chat panel to local files, Google Drive, and Dropbox PDFs. Developer APIs at api.pdf.ai parse documents into JSON, extract custom fields, and split files by section.

Most PDF chat tools stop at Q&A. PDF AI also ships a Parse API (POST /api/v2/parse), Extract API for invoice and form fields, and Split API for section-aware document breaks. Ultimate and Enterprise plans add specialized AI Agents for verticals like lease review, tax documents, and medical records, plus Capture and Ask screenshot questioning. SOC 2 Type II storage and a private-document mode that skips cloud retention address teams handling sensitive files.

Researchers, legal teams, and financial analysts use the chat interface for one-off document review. Developers embed the REST APIs into automation pipelines, with commercial API credit packs starting at $50 per month for 1,000 credits. The free Hobby plan allows 1 PDF upload and 100 questions per month to test the workflow before upgrading.

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.
