AskYourPDF

Overview

AskYourPDF is an AI-powered document chat platform used by more than 5 million people worldwide. It lets you upload a PDF or text document and immediately start asking questions in plain language, getting answers drawn directly from the content rather than generic AI responses. The platform was built to solve the problem of dense, time-consuming documents: instead of reading a 125-page report or a research paper end to end, you can ask specific questions and get cited, relevant answers in seconds. What sets AskYourPDF apart from basic PDF readers is the combination of breadth and model flexibility. The platform supports eight distinct AI models including GPT-5, GPT-5.2, Gemini 2.5 Flash, Claude 4.5 Sonnet, and Claude 4.5 Opus, so you can choose the model best suited to your task. It also handles scanned documents via OCR, connects to Zotero for academic reference management, and integrates directly into ChatGPT as a plugin. Document limits scale from 100 pages on the free tier up to 6,000 pages per document on Pro and unlimited on Enterprise, with file size caps reaching 877MB on Pro and 1,431MB on Enterprise. The platform has a particular foothold in academic and professional research. It is trusted by users at leading universities and has become a go-to tool for researchers who need faster access to insights from papers, theses, and textbooks than abstracts alone provide. Students use it to extract key points from course readings during exam preparation. Legal and business professionals use it to interrogate contracts, reports, and regulatory filings. The testimonials on the site specifically reference use cases like checking which services a service contract covers and synthesizing concepts spread across multiple chapters. Beyond the core document chat, AskYourPDF offers a summarisation service, a personal document library for organizing files, a Chrome extension for in-browser use, and iOS and Android mobile apps. A suite of 40+ free AI writing tools, including an essay maker, literature review writer, and thesis statement generator, extends the platform beyond PDF reading into broader academic writing support.

Best For

University students who need to extract key arguments and citations from research papers during exam prep or literature reviews, Academic researchers processing multiple papers per day who need faster access to findings than abstracts provide, Legal and compliance professionals reviewing contracts, regulatory filings, or policy documents to find specific clauses quickly, Business analysts and consultants who regularly work through lengthy reports and need to pull specific data points without full reads, Developers building document-intelligence features into apps using the AskYourPDF REST API, Knowledge workers who use Zotero for reference management and want to query their existing library without re-uploading files

How It Works

Start by creating a free account and uploading a PDF from your device. The free plan accepts files up to 15MB and 100 pages per document, with a limit of 1 document per day and 50 questions. Once uploaded, the document appears in your library and a chat interface opens alongside it. You type a question, for example 'What are the main findings?' or 'Which services are covered under Section 4?', and the AI returns an answer with references to the relevant pages in the document. On Premium and Pro plans, the Knowledge Base feature lets you add multiple documents to a single conversation. A Pro subscriber can upload up to 150 documents per day (each up to 6,000 pages and 877MB) and run up to 100,000 questions and 10,000 concurrent conversations. This makes it practical for team research sessions or multi-document legal review rather than one-off queries. The Pro plan also unlocks longer reply lengths and unlimited ChatGPT plugin questions. Model selection works at the conversation level. Standard queries run on GPT-5 Mini (available on all plans) or GPT-5.2 and Gemini 2.5 Flash (paid plans). For tasks requiring more depth, dense academic papers, nuanced contracts, you can switch to GPT-5, Claude 4.5 Sonnet, or Gemini 2.5 Pro, which run on a credit system. Premium subscribers receive 10 free credits per month; Pro subscribers receive 30. The Chrome extension adds a sidebar to any browser tab displaying a PDF, so you can query documents from journal websites or government portals without downloading anything. The Zotero plugin connects directly to your research library so existing references become queryable without re-uploading. Summaries can be generated on demand on paid plans, and all interactions happen within a GDPR-compliant infrastructure.
