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.

Memo AI is an AI-powered knowledge workspace founded in July 2023 by Jason Chan and a co-founder — both medical students in Hong Kong — originally as PDF2Anki and rebranded to Memo in October 2024. With 300,000+ users and $29K monthly recurring revenue bootstrapped, it processes PDFs, YouTube videos, websites, and text through a 6-phase RAG pipeline and generates eight distinct output types from a single source set: flashcards with spaced repetition, notes in six styles, mind maps, practice tests, learning tracks, infographics, AI-narrated podcasts, and voice-based tutor sessions — all with citation-verified answers and export to Anki, PDF, text, and Markdown in 99+ languages.

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.

• Content Studio with 8 Output Types — Generates flashcards, notes (bullet/table/Cornell/summary/toggles/custom), mind maps, practice tests (MCQ/SAQ/mixed), learning tracks, infographics, AI podcasts, and tutor sessions from a single uploaded source set — every format customizable by difficulty, style, question count, and language.

• 6-Phase RAG Pipeline with Hallucination Detection — Processes all sources through a six-stage pipeline: document ingestion with OCR, semantic chunking with context-aware boundary detection, OpenAI 1536-dimensional vector embedding, hybrid semantic + keyword retrieval with cross-document reasoning, multi-model AI generation, and quality assurance with hallucination detection and citation verification.

• Track Mode with AI Professor Voice Tutoring — Transforms dense documents into narrated walkthroughs: the AI explains concepts aloud, pages auto-flip in sync, diagrams and charts are verbally narrated, comprehension checks interrupt at key points, and voice conversations allow real-time Q&A in 32 spoken languages.

• Multi-Source Copilot with Exact Citations — Chat against all uploaded sources simultaneously using Claude, GPT, Gemini, DeepSeek, or Memo 1, with every answer citing the exact page number or video timestamp so every response is immediately verifiable without reopening the source.

• Flashcards with 6 Review Layouts + Smart Spaced Repetition — Supports basic, quiz, and cloze card types reviewed via Column, Toggle, List, Typing, Learn Mode, and Manual Grade layouts; intelligent spaced repetition schedules each card based on performance data; audio-based review and flashcard-level chat for misconception diagnosis built in.

• Anki Export with Cited Cards — Every generated flashcard includes a citation to the exact page or timestamp in the source document; export entire decks to Anki-compatible format for students with established Anki workflows, preserving card content and source linkage.

• Podcast Generation from Study Materials — Converts any uploaded source set into an AI-generated podcast with configurable style and duration — a uniquely passive study format that no other AI flashcard or study tool in this category offers, making dense material accessible during commutes or hands-free sessions.

• 99+ Input Languages, 32+ Spoken Output Languages — Processes source content in over 99 languages and supports voice output in 32 languages for Track Mode narration, making Memo one of the most linguistically inclusive AI study tools available globally.

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
  • Founded by 2 medical students actively using the product for the same exam types as their users — every feature reflects genuine firsthand academic use-case knowledge
  • 300,000+ users and $29K MRR bootstrapped is one of the strongest independent growth signals in the AI study tools category
  • 6-phase RAG pipeline with Phase 6 hallucination detection and citation verification makes source-linked outputs measurably more trustworthy than tools without explicit quality assurance
  • Eight distinct Studio output types — including AI-generated podcasts and infographics — from a single source set with no extra charge
  • Direct Anki export with source citations serves medical students and serious flashcard users who already have established Anki workflows
  • Free plan includes all eight Studio output types with no credit card required — the most generous feature-access free tier in the AI flashcard category
  • Track Mode's voice-narrated AI Professor with auto page-flipping is a uniquely passive study format absent from every competing tool at this price point
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
  • Energy credit system means heavy Studio users running multi-source generation sessions can deplete monthly allowances faster than the nominal per-month figure implies
  • Free plan's 30 energy per month and 50 MB file limit allows only limited generation before upgrade pressure kicks in
  • Bootstrapped 2-person founding team means feature development pace and support response time are constrained by team capacity, even with active build-in-public transparency from co-founder Jason Chan
  • No built-in citation management or reference library for academic paper workflows — Memo is a study and retention tool, not a research and writing platform
  • Podcast and infographic generation, while unique, are one-directional passive outputs with limited post-generation editing compared to dedicated podcast or design tools
  • No LMS integration with Canvas, Blackboard, or Google Classroom for automatic course material import

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.

Memo's deepest technical differentiator is its 6-phase RAG pipeline with explicit Phase 6 quality assurance — an architecture rare in student-focused AI tools and typically found only in enterprise knowledge management platforms.

• Phase 6 RAG Quality Assurance with Hallucination Detection — Most AI study tools generate outputs and deliver them immediately. Memo's pipeline validates every generated response against source documents, detects hallucinations, verifies citations, and assigns confidence scores before output delivery — making its Copilot answers measurably more trustworthy than tools without an explicit quality gate.

• AI Podcast Generation from Study Materials — No other AI flashcard or study guide tool in this category offers AI-generated podcast output from your own uploaded course material. Memo converts any source set into a listenable study podcast with configurable style and duration, enabling passive study during commutes, exercise, or hands-free sessions — extending the reach of study time beyond screen time.

• Track Mode with Auto Page-Flip and Visual Narration — The AI Professor voice tutor narrates document content, flips PDF pages in sync, verbally explains diagrams and charts, and pauses for comprehension checks — functioning as a self-guided narrated textbook. No competing AI flashcard or study guide tool offers synchronized voice navigation through an uploaded PDF at this level of integration.

• Built by Active Medical Students, Used by Their Peers — Memo's founding story is not marketing — Jason Chan is publicly documented as a fourth-year medical student actively building the product while in clinical training. The cloze card support, Anki export, Deep Dive generation mode, and OCR for scanned clinical documents were all built by someone sitting the same exams as Memo's primary user base.

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.

Memo AI is a multi-platform workspace designed to ingest sources from everywhere students and professionals actually encounter them and export to the tools they already use for review.

• Anki Export — Exports complete flashcard decks to Anki-compatible format with source citations preserved, serving the large population of medical and professional exam students who rely on Anki's proven review algorithm and do not want to abandon established study workflows.

• PDF Upload with Page Range Selection — Users can specify exact page ranges before processing rather than ingesting entire documents, enabling targeted flashcard and note generation from specific chapters or sections without processing irrelevant material.

• YouTube Lecture Ingestion — YouTube video URLs are processed via transcript-based context extraction, allowing structured study outputs from any publicly available lecture, course video, or educational content without downloading or re-watching.

• Multi-Format Export — Finished outputs export to Anki (.apkg), text, PDF, and Markdown formats, covering every downstream tool a student or professional might use for review, sharing, or documentation.

• Multi-Model AI Backend — Copilot supports Claude (Anthropic), GPT-5.2 and GPT-4.1 (OpenAI), Gemini 3.0 Flash (Google), DeepSeek V3.2, and the proprietary Memo 1 model — giving users model selection flexibility without locking outputs to any single provider's availability or capability.
