Twinbook transforms static books, videos, notes, and PDFs into adaptive learning systems that remember context and evolve with every learner. Not another AI wrapper — a fundamentally new architecture powered by context and memory.
For Creators
Twinbook turns what you've already built into a living, adaptive learning system. You've spent years creating great content — books, videos, courses. But a PDF doesn't know who's reading it. A video can't tell if someone's confused.
This isn't another AI tool that summarizes your work. This is your content, made intelligent.
Books, videos, lecture recordings, notes, and PDFs — upload anything. Twinbook automatically detects the content type and builds the learning architecture around it.
Every piece of content is transformed into structured learning experiences: blog-style summaries, practice questions, smart flashcards, and interactive Q&A.
Twinbook remembers what each learner has seen, what they got wrong, and what they need next. Every interaction is informed by the full context of their learning journey.
See how learners engage with your material. Track comprehension across concepts, identify where students struggle, and understand what's working.
Your content, your rules. Decide what gets generated, how it's delivered, and who gets access. Twinbook amplifies your expertise — it doesn't replace it.
Not an AI wrapper. Most tools bolt a chatbot onto your content. Twinbook builds a genuine understanding of your material — the concepts, the relationships, the progression.
Powered by context and memory. The system doesn't start from scratch every session. It carries forward what it knows about the content and the learner.
Your audience grows. Static content reaches one person one way. Adaptive content reaches every person their way.
For Students
Whether you're in medical school, law, engineering, science, or K-12 — the challenge is the same. Hundreds of lectures, thousands of pages, and making meaningful connections between what you learned last week and what you're studying today. Until now.
Record a lecture — Twinbook extracts the full conceptual structure
Get structured notes with key insights and visual breakdowns
Adaptive flashcards with spaced repetition target what matters
Micro-learning fills gaps across four phases: Understanding, Application, Analysis, Synthesis
Everything connects — concepts from last month's lectures link to today's material
“I was reviewing a topic and the system referenced a concept from a lecture three weeks ago — one I'd gotten wrong on a practice question. It didn't just remind me. It re-taught it in the context of what I was studying now. That's when I realized this wasn't just flashcards.”
Ask questions in natural conversation and get instant explanations grounded in your content. Your AI tutor knows what you've studied, what you've struggled with, and explains things in context.

Quick answers to common questions about Twinbook.
Twinbook was created by a parent and technologist who saw firsthand how rapidly technology is evolving — and how children, families, and educators are struggling to keep pace.
While AI and digital tools are advancing at unprecedented speed, many students are not yet equipped to use these technologies thoughtfully, safely, and to their full advantage.
Twinbook was built to bridge that gap.
The product is shaped by real-world challenges faced by families and educators, and continues to evolve with input from teachers, parents, and professionals across education and child development.
We are informed by conversations with educators, medical professionals, and industry practitioners who care deeply about how technology impacts young learners.
