Under the hood

Built on intelligent
foundations

Memo's RAG engine is deceptively simple to use, but under the hood lies a sophisticated pipeline that ensures accurate, contextual, and trustworthy AI responses.

Phase 1 of 6
Phase 01

Parse & understand your content

Memo's ingestion engine processes PDFs, slides, videos, and text with intelligent parsing. We extract text, tables, images, and structure—preserving context that other systems lose.

Powered by Memo Parser
Specification
  • 1.1Multi-format parsing (PDF, PPTX, DOCX, video)
  • 1.2OCR for scanned documents and images
  • 1.3Table and chart extraction
Phase 2 of 6
Phase 02

Intelligent content segmentation

Unlike basic chunking that splits text arbitrarily, our semantic chunker understands document structure. It creates meaningful segments that preserve context and relationships between concepts.

Powered by Semantic Engine
Specification
  • 2.1Context-aware boundary detection
  • 2.2Hierarchical chunk relationships
  • 2.3Metadata preservation and enrichment
Phase 3 of 6
Phase 03

Transform meaning into mathematics

State-of-the-art embedding models convert your content into high-dimensional vectors that capture semantic meaning. Similar concepts cluster together, enabling intelligent retrieval.

Powered by OpenAI Embeddings
Specification
  • 3.11536-dimensional semantic vectors
  • 3.2Multi-lingual understanding
  • 3.3Real-time index updates
Phase 4 of 6
Phase 04

Find exactly what matters

When you ask a question, our retrieval system doesn't just match keywords—it understands intent. Hybrid search combines semantic similarity with keyword matching for precise results.

Powered by Memo Retriever
Specification
  • 4.1Hybrid semantic + keyword search
  • 4.2Cross-document reasoning
  • 4.3Relevance scoring and reranking
Phase 5 of 6
Phase 05

Synthesize intelligent responses

Retrieved context is fed to your choice of AI model—GPT-4, Claude, or Gemini. The model synthesizes information from multiple sources into coherent, accurate answers grounded in your documents.

Powered by Multi-Model AI
Specification
  • 5.1Multi-model support (GPT-4, Claude, Gemini)
  • 5.2Context-aware response generation
  • 5.3Source citation and attribution
Phase 6 of 6
Phase 06

Verify accuracy & citations

Every response is validated against source documents. We verify claims, check for hallucinations, and ensure citations are accurate—so you can trust what Memo tells you.

Powered by Memo Validator
Specification
  • 6.1Hallucination detection
  • 6.2Citation verification
  • 6.3Confidence scoring
Our story

Built by 2 med students with a child's imagination

Memo started when two medical students got tired of losing insights buried in hundreds of pages of dense material. So we built an AI workspace that actually helps you retain what you read—whether that's research papers, technical docs, or the quarterly report you've been putting off.

About us

Loved by learners
around the world

Don't just take our word for it. Join 200,000+ people who retain more of what they read with Memo.

From our founder

Welcome to the age of
AI-native knowledge

The greatest breakthroughs in human potential come when we remove the barriers to knowledge acquisition. Yet our tools for processing information remain stubbornly inefficient—fragmenting attention across apps, losing context, forgetting what we read.

We're all drowning in information. Researchers sift through hundreds of papers. Professionals juggle reports, docs, and endless updates. Students face more material than ever before. The volume keeps growing, but our ability to retain it hasn't changed.

The root issue? We were never given tools designed for how memory actually works.

AI represents an unprecedented opportunity—not just to manage information, but to truly internalize it. Our AI-first platform is built on a unified system with three components designed to transform how you work with knowledge.

Content Processing extracts knowledge from any source—PDFs, videos, audio—understanding text, diagrams, and relationships automatically. AI Copilot helps you explore, question, and synthesize what you've uploaded. Retention Tools use active recall and spaced repetition to make knowledge stick.

All three work together and improve with every session. That's what makes Memo a complete AI-native knowledge workspace. Join me on this journey, and let's build something amazing together.

With love,

Jason
