Memo AI

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.

• 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.

Memo AI is built for learners at any level who need to convert dense source material into active recall study systems — particularly those studying from video lectures, scanned documents, or large multi-source content sets.

• Medical and professional licensing exam students — USMLE, NCLEX, bar exam, and CPA candidates use the cloze card generation, Deep Dive mode, spaced repetition scheduling, and direct Anki export to cover high-volume memorization requirements without manual card creation.

• University students learning from video lectures — YouTube lecture ingestion with transcript-based context and Track Mode narration let students extract structured flashcard decks and guided walkthroughs from hours of recorded lectures faster than re-watching.

• Professionals and researchers processing dense documents — Multi-source Copilot with cross-document reasoning, infographic generation, and podcast output allow professionals to extract structured knowledge from technical reports and research papers without linear full-document reads.

• Language learners and international students — 99+ input languages and 32 spoken output languages make Memo one of the most accessible AI study tools for non-English learners who study in multiple languages simultaneously.

• Students transitioning from Anki or Quizlet — Users with established Anki workflows use Memo to automate card creation from their lecture materials while exporting to Anki for review, combining Memo's generation speed with Anki's mature review algorithm.

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.

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.

Memo AI is the most technically sophisticated AI study tool available at its price point in 2026 — built by two bootstrapped medical students who shipped a 6-phase RAG pipeline with hallucination detection, eight distinct Studio output types including AI podcasts, a voice-narrated AI Professor with auto page-flip, and direct Anki export at $7.17/month annually.

The energy credit model creates consumption awareness for heavy users, and the two-person founding team is a real constraint on support depth. For students, researchers, and professionals who want to genuinely internalize dense source material rather than passively encounter it, Memo V8 is the most complete active recall study workspace in the market today.
