PDF Chat AI — Your Whole PDF Library

A persistent AI library for your PDFs: upload collections, chat across every document, and jump to cited pages.

Stop re-uploading the same PDF every session. PDF Chat AI is a persistent, growing library of your PDFs that you can chat with — across all documents in a collection at once, not one file at a time. Why researchers, lawyers, and analysts pick it: Chat with multiple PDFs simultaneously — ask one question, get one answer synthesized across every document in the collection. Real citations — every claim carries an inline [source, p.X] chip; click it and the built-in viewer opens that PDF at that exact page. A library, not a chat box — collections/folders in a left rail, per-file status chips (queued → processing → ready), nothing silently stuck or lost. Lives in Chrome's side panel — stays open while you browse; capture any PDF from the web with right-click → "Add PDF to Library", or drag-and-drop files. Keyboard-first — Ctrl/⌘+K quick-switcher across collections and documents; dark & light themes. Search-quality answers. Hybrid retrieval (semantic + full-text) over your whole collection, tuned for research papers, contracts, case files, reports, textbooks, and financial filings. Your documents are processed only to answer your questions and are never used to train AI models. Delete any document or collection at any time. Privacy policy: https://api.levelup123.xyz/privacy
