Your Personal AI Learning Coach
Three pillars of intelligent learning — working invisibly so you can focus on what matters.
Invisible Intelligence Layer
Butterfly makes learning more fun by removing the friction. You don't have to keep track of what you've learnt anymore. You also don't have to worry about when to review what you've learnt. All you need to do is focus on the learning; Butterfly takes care of the rest.
Automatic Screen Capture
Butterfly automatically captures what you're learning without any manual input required.
Smart Progress Tracking
Track your learning journey automatically as you engage with content across different platforms.
Works in the Background
Minimizes to invisibility and works seamlessly without any additional effort from you.
Closed Loop Learning
Butterfly closes the open loop in learning by helping you remember. Do you remember what you had for lunch 2 days ago? Do you remember about the last book you read? Do you remember the last reel you watched yesterday? Probably not... But with Butterfly, you will.
Intelligent Spaced Repetition
Optimized for long-term retention with spaced repetition tailored to your unique memory patterns.
AI-Powered Adaptation
Active recall exercises personalized to your knowledge gaps. The system surfaces the right concept at the right time, in the right form, with the right level of challenge.
Auto-Generated Practice
Practice problems and quizzes automatically generated based on your learning activity.
Unlock Expert Thinking
Butterfly helps you develop expert thinking by building connections between different ideas. You will find learning a lot easier as you start to see connections within varioous topics of a subject and across learning subjects. By prioritizing understanding as a network, you can learn faster and remember more.

Why Cognition Is Different
Not a Second Brain
We don't aim to help you store more information outside of your brain. Instead, we empower you to reinforce your memory, like an add-on to your learning brain.
Not a Learning Platform
We don't provide courses for you to follow along. Instead, we bring structure and longevity to whatever you are learning—on your terms.
Not an AI Chatbot
We don't provide one-off responses to your learning questions. Instead, we leverage pre-existing knowledge to help you make connections with content you already know.
