About xPDF AI

xPDF AI, published by PDFChat, is a document assistant built around the observation that most PDF chat tools handle prose well and everything else badly. Its stated focus is tables and figures: you can ask it to explain a specific chart, a data table or a diagram inside a PDF and get an answer grounded in that element rather than in the surrounding text. On top of question answering it does semantic search across documents — targeting intent rather than keyword matches, which is the failure mode of built-in PDF search — plus report generation and knowledge-graph construction, both metered separately from ordinary questions. Document libraries let related PDFs be grouped and queried together, which is the difference between asking about one paper and asking across a literature set. The audience is spelled out on the site as students, researchers and legal users, and the vendor claims over 10,000 users. Pricing is per member per month with two meters running simultaneously — pages processed and question credits — and both overflow at $0.50 per unit, which makes heavy use expensive and is worth modelling before committing: the $10 Starter tier includes 200 pages and 50 questions a month, so a single long document can consume most of a month's page allowance. The $50 Pro tier moves to 500 pages and 200 credits and adds two free report generations and two knowledge graphs a month; the $100 Ultra tier doubles those again. Annual billing saves 25%. Enterprise adds multiple workspaces, unlimited credits and pages, sharing and a dedicated support team, and is quoted directly.
