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.

Gatsbi is an AI research automation platform launched in 2024 and trusted by 100,000+ researchers and innovators in 150+ countries. It operates through three core modules — Gatsbi Innovator (research gap detection and idea generation), Gatsbi Writer (full paper manuscript generation with citations, equations, and figures), and Gatsbi Reviewer (systematic reviews and meta-analyses) — plus a dedicated Patent Disclosure module that writes complete patent documents in 11 languages.

Powered by a multi-agent AI pipeline orchestrating GPT, Qwen, DeepSeek, and Llama models with a Deep Research Agent introduced in Gatsbi 3.0, it is the only AI platform in production that covers the complete workflow from original idea discovery through publication-ready manuscript in a single environment.

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.

• Gatsbi Innovator — AI Research Gap Detection & Idea Generation — Inputs your research topic and generates 10+ innovative ideas with originality scores, detailed implementation paths, and supporting references — identifying unexplored directions before any writing begins.

• Gatsbi Writer — Full Research Paper Generation — Automatically identifies your paper type (methodological, experimental, case-study, clinical, or mixed-methods) and generates a complete manuscript with structured sections, equations, tables, figures, in-text citations, and a formatted reference list in APA, IEEE, Harvard, Chicago NB, or AMA style.

• Deep Research Agent (Gatsbi 3.0) — Autonomously browses academic literature and public datasets, downloads and analyzes open data, and synthesizes evidence-backed findings when your research notes lack complete results — so paper generation can begin from instructions alone.

• Gatsbi Reviewer — Systematic Reviews & Meta-Analyses — Screens academic literature by topic and optional year filters, extracts structured data, generates analytical dimensions, and produces statistical plots and calculations for publication-ready systematic review and meta-analysis outputs.

• AI Patent Disclosure Drafting in 11 Languages — Generates complete patent disclosure documents covering background surveys, invention descriptions, novelty analyses, drawings, embodiments, and claims in 11 languages — applicable to both AI-generated solutions and user's prior research.

• Multi-Model AI Pipeline — Orchestrates multiple AI models including different versions of GPT, Qwen, DeepSeek, and Llama in a coordinated multi-agent agentic workflow, balancing capability and cost optimization across different tasks in the research process.

• Desktop App with Local Storage — Available as a desktop application with your entire usage history stored locally on your device for Pro users — no cloud upload of activity data, addressing privacy concerns for sensitive pre-publication research.

• Humanizer Plugin — Processes generated paper manuscripts to optimize language patterns for natural academic tone and reduce the likelihood of AI detection flags, available through the Plugin Credits system as an add-on to any Pro subscription.

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
  • The only AI research platform combining idea discovery, full paper generation, systematic reviews, meta-analyses, and patent disclosure drafting in one multi-agent workflow
  • Deep Research Agent in Gatsbi 3.0 autonomously collects and synthesizes evidence from public literature when user research notes are incomplete — enabling draft generation from instructions alone
  • Patent Disclosure generation in 11 languages covers a capability entirely absent from every competing academic writing tool in this category
  • Desktop app with local history storage gives privacy-conscious researchers a tool that keeps sensitive pre-publication work off cloud servers
  • Multi-model AI pipeline (GPT, Qwen, DeepSeek, Llama) optimizes quality and cost across different research workflow tasks rather than being locked to a single API
  • Yearly Pro at $159.99/year ($13.33/month) covers unlimited usage across all three core modules without per-document caps
  • Trusted by PhD-level users at XREAL Inc. and Sigma Squares Tech, with testimonials confirming production-level research workflow use
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
  • Independent testing by Originality.ai found Gatsbi-generated manuscripts detected as 100% AI-generated even after the Humanizer plugin is applied — a critical issue for journals with AI content policies
  • Plugin Credits for the Humanizer are a separate paid layer on top of the Pro subscription — the most in-demand add-on is not included in the base plan price
  • Gatsbi explicitly states users must verify AI-generated idea feasibility, conduct actual experiments, and document real results — the tool is an accelerator, not a replacement for genuine research work
  • Web version is only available for Pro subscribers — free users are limited to the desktop app download
  • As a 2024-launched platform with a small team, reference accuracy in generated manuscripts requires careful human verification before submission to peer-reviewed journals
  • The free plan is described as offering only "basic features with limited usage" — the free tier is insufficient for evaluating the full paper generation workflow meaningfully
  • No collaborative multi-user workspace or shared library — currently a single-user tool without team research features
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.

• Students & Academic Researchers — Upload research papers, textbooks, and dissertations to extract cited answers, generate literature review summaries, and create thesis statement drafts — cutting research time significantly.

• Legal & Compliance Professionals — Use the Knowledge Base to query multiple contracts and regulatory documents simultaneously, surfacing specific clauses and compliance requirements without full manual review.

• Business Professionals & Executives — Process technical manuals, RFP documents, financial reports, and meeting transcripts to extract the data points and decisions you need in seconds.

• Developers & Enterprise Teams — Use the REST API to embed AskYourPDF's document intelligence directly into internal tools, customer-facing apps, and automated document processing workflows.

• Medical & Healthcare Professionals — Review patient documentation, clinical research papers, and medical manuals quickly — the platform supports documents up to 877MB on the Pro plan and unlimited pages on Enterprise.

Gatsbi is built for researchers, engineers, and innovators who need to produce structured academic or technical documents faster — with the understanding that AI-generated outputs require human validation before submission.

• STEM researchers and academics at ideation stage — Gatsbi Innovator identifies research gaps and generates scored, implementable ideas before paper drafting begins, replacing the blank-page problem that slows the earliest stage of every research project.

• Research scientists under publication deadlines — Gatsbi Writer produces complete, section-structured first drafts with real citations from research notes, giving researchers a complete manuscript skeleton to refine rather than starting from nothing under submission pressure.

• R&D teams and startup engineers filing patents — The Patent Disclosure module in 11 languages generates documentation covering every required section of a patent application without a dedicated IP writing specialist on the team.

• Systematic reviewers in clinical and social sciences — Gatsbi Reviewer's automated screening, extraction, and statistical synthesis compresses the most time-intensive phases of systematic reviews and meta-analyses into a fraction of the manual workload.

• Privacy-sensitive researchers — Researchers handling pre-publication findings who prefer local data storage over cloud-processed content can use the desktop version knowing their usage history never leaves their device.

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.

Gatsbi's deepest architectural advantage is its multi-agent research pipeline — an agentic system that coordinates multiple AI models across ideation, writing, reviewing, and patent drafting, rather than applying one model to all tasks uniformly.

• Research Gap Detection with Originality Scoring — Gatsbi Innovator does not just list topic ideas; it evaluates each generated idea against existing literature, assigns originality scores, and provides detailed implementation paths — functioning as an AI co-scientist that validates novelty before any writing begins. No competing AI writing tool at any price offers this as a built-in workflow step.

• Patent Disclosure Generation in 11 Languages — Every other academic AI writing tool reviewed in this category focuses exclusively on journal papers, theses, or literature reviews. Gatsbi's Patent Disclosure module generates complete, multi-section patent documentation in 11 languages, serving an entirely different output type that researchers, engineers, and R&D teams at innovation companies genuinely need.

• Autonomous Deep Research Agent (Gatsbi 3.0) — When research notes are incomplete, the Deep Research Agent does not stop and ask for more input. It autonomously plans research tasks, downloads and reads open-access literature, analyzes available public datasets, and synthesizes evidence-backed findings — enabling a researcher to generate a complete paper draft from a topic description alone.

• Desktop App with On-Device Local History — Privacy-first researchers can run Gatsbi entirely as a desktop application with their full usage history stored locally, never uploaded to cloud servers. No other AI paper writer in this category offers a local-storage desktop architecture for privacy-sensitive pre-publication work.

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.

• ChatGPT Plugin (GPT Store) — The official AskYourPDF GPT plugin integrates directly into ChatGPT, allowing users to upload and chat with documents inside the ChatGPT interface — a seamless experience for existing ChatGPT users.

• Zotero Plugin — Integrates with Zotero's academic reference management workflow, enabling researchers to generate summaries, extract key insights, and interact with their full Zotero library using AskYourPDF's AI document chat engine.

• iOS & Android Mobile Apps — Full AskYourPDF functionality is available on both iOS and Android smartphones — upload documents from your phone's local storage or cloud and query them on the go.

• REST API for Developers — A documented REST API with Developer documentation and a Getting Started guide allows developers to embed AskYourPDF's document intelligence into custom web apps, enterprise platforms, and automated processing pipelines.

Gatsbi is a desktop-first platform with a web interface for Pro users, designed to produce export-ready documents in standard academic and patent formats.

• Desktop App (Windows/Mac) — The primary Gatsbi application installs as a desktop program on your computer, with all usage history stored locally for Pro users — compatible with standard Windows and macOS environments without browser dependency for the core writing workflow.

• Web Version (Pro Users) — Available via the Gatsby user space portal for Pro subscribers, providing browser-based access to Innovator, Writer, and Reviewer modules from any device without installing the desktop app.

• Multi-Citation Style Output — Exports formatted reference lists and in-text citations in APA, IEEE, Harvard, Chicago (NB), and AMA styles — covering the five citation formats required for the most common STEM, social science, and medical journal submission systems.

• 11-Language Patent Disclosure — Generates patent documentation in 11 languages, covering all major patent filing jurisdictions globally including English, Chinese, German, French, Japanese, and other languages relevant to international PCT patent applications.

• Multiple AI Model Backends — Orchestrates GPT (OpenAI), Qwen (Alibaba), DeepSeek, and Llama model families in a coordinated multi-agent workflow, meaning the platform is not locked to a single provider's API availability or pricing — ensuring continuity if any single model provider experiences outages.
