Overview

AskYourPDF is an AI-powered document intelligence platform co-founded in 2023 by Emmanuel Olarewaju David, Oluwasesan Yackson, and Isaac D., and operated by ProtonLabs Technology Inc in Birmingham, England. It allows users to upload PDFs, Word documents, and other files and interact with them via natural-language chat — asking questions, generating summaries, and extracting cited insights in seconds. Trusted by 5M+ users, it's available on web, Chrome extension, iOS, Android, and as a ChatGPT plugin.

SciSpace (formerly Typeset.io) is an AI-powered academic research platform developed by Typeset, Inc. that gives users access to over 285 million research papers through natural-language semantic search, PDF chat, automated literature review, and AI-assisted academic writing.

Trusted by over 1 million researchers from 100+ countries — including faculty at MIT, Stanford, and Yale and researchers at Nobel Prize-winning institutions — the platform covers the full academic workflow from paper discovery to manuscript drafting, with automatic citations and Zotero, Mendeley, and CSV export support.

Key Features

• Chat with Documents — Upload a PDF, Word document, or text file and ask it questions in plain English; the AI returns precise answers with cited page references so you can verify the source instantly.

• Knowledge Base (Multi-Document Chat) — Combine multiple uploaded documents into a single Knowledge Base and query across all of them simultaneously — ideal for comparative research, contract review, and academic literature analysis.

• OCR Support — Reads and processes scanned PDFs and image-based documents using Optical Character Recognition, making handwritten notes, legacy contracts, and non-digitized materials fully queryable.

• Multi-Model AI Support — Choose from GPT-5, GPT-5.2, GPT-5 Mini, GPT-5 Nano, Gemini 2.5 Flash on standard plans, with Claude 4.5 Sonnet, Claude 4.5 Opus, and Gemini 2.5 Pro available via credits for premium output quality.

• Summarisation Service — Condenses lengthy documents into structured, readable overviews — available on Starter, Pro, and Enterprise plans — without requiring you to manually prompt a summary format.

• ChatGPT Plugin & Zotero Integration — Chat with your documents directly inside ChatGPT using the official AskYourPDF plugin, and connect with Zotero to summarize and extract insights from your academic reference library.

• Chrome Extension — Install the browser extension to upload, chat with, and summarize documents directly from your browser without navigating to the AskYourPDF web app.

• 40+ Free AI Writing Tools — A built-in suite of free tools including a Literature Review Writer, AI Essay Maker, AI Thesis Statement generator, AI Paragraph Generator, and 35+ more — available on all plans with no credit consumption.

• Semantic Search Across 285 Million Papers — Submit a research question in plain language instead of keywords; SciSpace returns a synthesized cited answer plus ranked individual papers, letting you find relevant literature that keyword searches would miss.

• AI Extraction Columns — Add custom analysis columns across your entire paper library simultaneously; compare methodologies, conclusions, limitations, or any custom criteria across dozens of PDFs in a unified sortable table without opening a single document.

• Chat with PDF — Upload any paper and ask questions about its content in natural language; responses include page-level source citations and correctly interpret figures, tables, equations, and methodology sections.

• Deep Review Agent (Advanced) — Triggers an autonomous AI agent that processes up to 1,750 papers, identifies the most relevant subset, and generates a structured comprehensive literature synthesis with in-text citations — replacing weeks of manual systematic review screening.

• AI Writer with Real-Time Citation Suggestions — Drafts academic text in real time while recommending relevant citations directly from the SciSpace database; the reference list updates automatically as you write.

• Library Search & Report Writing Sub-Agent (2026) — Import your own PDFs or Zotero/Mendeley libraries and instruct the sub-agent to generate a full manuscript-style research report with proper academic structure, including introduction, body sections, and a reference list.

• Paraphraser with 20+ Tones — Rewrites academic text across more than 20 preset tones (formal, simplified, technical, accessible), translates text into any language, and adjusts output length to suit different publication or audience requirements.

• AI Content Detector & Plagiarism Check — Analyzes documents sentence-by-sentence for AI-generated content and runs Turnitin-powered plagiarism detection, addressing growing institutional academic integrity requirements for submissions.

Pros

Multi-document Knowledge Base lets you query across multiple files simultaneously — essential for research and legal review workflows
OCR support processes scanned and image-based PDFs — most free PDF chat tools don't support non-text documents
Multi-model support (GPT-5, GPT-5.2, Gemini 2.5 Flash, Claude 4.5 Sonnet) lets you choose the best AI per document type
Native ChatGPT plugin integration lets you chat with PDFs directly inside the ChatGPT interface
Zotero plugin bridges the gap between document chat and academic reference management
40+ free AI writing tools available on all plans — including a Literature Review Writer and AI Essay Maker — at no extra cost
GDPR-compliant with full encryption — your documents and data meet the highest standard of data security

Semantic search queries 285 million papers in natural language — no keyword guessing required
Free plan requires no credit card and is functional enough for daily light research use
Premium plan at $12/month annually includes unlimited search, AI Writer, high-quality models, and RIS/CSV export
PDF Chat cites the exact page and passage for every AI response, making verification instant
Zotero and Mendeley import support connects your existing reference library without manual re-uploading
Deep Review processes up to 1,750 papers and produces a structured review synthesis in minutes
Coverage of 55,000+ research institutions and 150 publishing partners ensures broad database access

Cons

Free tier is restrictive — only 1 document per day, 100 pages, and 50 questions before hitting limits
Multiple Trustpilot reviewers flag aggressive auto-renewal billing practices and a reported no-refund policy — review subscription terms carefully before upgrading
Technical bugs and occasional unreliable performance have been reported by users, particularly during high-traffic periods
Premium models (Claude 4.5 Opus, Gemini 2.5 Pro) require separate credits on top of the monthly subscription fee — an additional cost that adds up for heavy users
No dedicated academic research features like automated citation generation or structured literature search — requires pairing with a separate research tool
Small founding team (2–10 employees) means platform stability and support capacity may lag during rapid growth periods

Deep Review is locked exclusively behind the Advanced plan at $90/month — a steep jump from Premium at $20/month
Free plan restricts export to Zotero, BibTeX, and CSV formats, forcing paid upgrade for standard reference workflows
AI extraction columns and semantic search are not fully reproducible, making the tool unsuitable as the primary search method for formal systematic reviews
PDF Chat accuracy drops with highly visual, formula-heavy, or data-table-dense papers outside standard text-based formats
No dedicated desktop app or mobile app — the platform is browser-only, limiting offline or on-the-go research use
Teams plan at $18/user/month is priced competitively but lacks granular admin controls reported by enterprise reviewers

Best For

AskYourPDF is designed for anyone who regularly works with large volumes of documents and needs to extract specific information faster than manual reading allows.

Unique Features

AskYourPDF stands apart in the document chat space by combining multi-format document support, multi-model AI flexibility, and native ecosystem integrations that most PDF chat tools don't offer.

• ChatGPT Native Plugin Integration — AskYourPDF is one of the few document intelligence tools with an official ChatGPT plugin, letting you chat with your uploaded PDFs directly inside the ChatGPT interface — without opening a separate app or tab.

• Zotero Plugin for Academic Workflows — Most PDF chat tools ignore academic reference management. AskYourPDF's Zotero plugin bridges document chat with one of the most widely used academic reference management systems, enabling researchers to summarize and query their entire reference library through a single integration.

• OCR for Scanned Documents — Unlike many PDF chat tools that only process machine-readable text, AskYourPDF's OCR engine reads scanned documents, photographed pages, and image-embedded PDFs — dramatically expanding the range of documents you can work with.

• Multi-Model Flexibility Including Claude 4.5 & Gemini 2.5 Pro — While most document chat tools lock you into one AI model, AskYourPDF lets you choose between GPT-5, GPT-5.2, Gemini 2.5 Flash, Claude 4.5 Sonnet, Claude 4.5 Opus, and Gemini 2.5 Pro per document session — allowing model switching based on the document type and precision required.

• 40+ Free AI Writing Tools for All Users — A built-in suite including a Literature Review Writer, AI Essay Maker, AI Thesis Statement generator, and 35+ more tools is available on all plans at no extra cost — making AskYourPDF more than a single-function PDF reader.

SciSpace stands apart by covering the full academic research workflow end-to-end — discovery, analysis, synthesis, and writing — in a single platform without requiring tool-switching.

• Deep Review Agent with 1,750-Paper Processing — No competing AI research tool at this price point autonomously screens this volume of papers, identifies the most relevant subset, and produces a structured cited synthesis in one continuous agentic operation. For systematic review preparation, it replaces weeks of manual abstract screening.

• PDF-to-Video Converter — SciSpace converts research papers into AI-narrated video summaries shareable on social media platforms — a unique capability for science communicators and educators that no other dedicated academic research tool currently offers.

• Turnitin-Powered Plagiarism Detection Built In — Unlike standalone AI writing tools, SciSpace integrates institutional-grade plagiarism detection directly inside the platform, letting researchers check academic integrity without subscribing to a separate service.

• Multi-Language Chat with Any Paper — The Chat with PDF feature operates in any language regardless of the source paper's language, enabling researchers to extract insights from international literature in their native language — a critical capability in multilingual academic environments.

Integrations

AskYourPDF operates across all major platforms and integrates with tools already embedded in academic, professional, and developer workflows.

• Chrome Browser Extension — The official AskYourPDF Chrome extension lets you upload and interact with documents directly from your browser, eliminating the need to navigate to the web app for quick document queries on any website.

SciSpace runs as a web app accessible in all major browsers and includes a Chrome extension for reading papers directly on any website.

• Chrome Browser Extension — Install from the Chrome Web Store and interact with any research article page directly in your browser; ask questions, get summaries, and translate findings without leaving the page or importing files manually.

• RIS, CSV, and BibTeX Export (Premium and above) — Export your annotated paper library and citation data to standard reference manager formats compatible with Zotero, Mendeley, EndNote, and LaTeX workflows.

• ChatGPT Custom GPT Integration — SciSpace connects with ChatGPT Plus via a custom GPT assistant, combining SciSpace's 285-million-paper database with ChatGPT's conversational interface for citation-backed answers directly inside ChatGPT.
