About this app

Stop blindly memorizing. Become each other's "guides" and understand the fundamental principles first.

The most frustrating moments while studying are those times when you're forced to memorize concepts that you can't understand no matter how much you read. And there are times when you ask questions, but no one answers, leaving you feeling left alone.

Essential Note is a learning question community that helps you break free from this memorization-focused learning and the waiting gap, and helps you understand the core of knowledge by comparing it to simple situations you already know.

■ Learning through "Essential Notes" instead of Memorization

1. Questions that Open Your Mind: "What exactly does this concept mean?" Someone will explain this with a familiar metaphor, saying, "It's like ○○." Connecting difficult concepts to simpler situations provides a clue to understanding.

2. We Are All "Guides" In Eessential Note, there's no rigid "choice" process where you choose a single correct answer. Instead, if your explanation helps someone understand, you'll be remembered as a "guide." Anyone can be a questioner, and anyone can be a guide for others.

■ "AI Guide" that never stops, even when alone

1. Initial Answers to Reduce Waiting For those times when you've posted a question but don't receive an immediate response, the "AI Guide" is available in Biyunote. If there's no response for a certain amount of time, the AI ​​Guide begins a conversation with basic explanations and analogies.

2. A Stepping Stone for Human Responses: The AI ​​Guide's answers aren't the correct answers, but rather the initial guidance and starting point for a conversation to facilitate understanding. Friends' responses then follow, deepening your understanding.

■ "Lamps" and "Title"s that Show Your Learning Journey

1. Heartfelt Support: Lanterns: If your answers were helpful, your friends will light a "Lamp". The accumulated lanterns on your profile allow you to see at a glance how many people you've helped.

2. Based on your natural growth record and title activities, you'll be given titles like "Guide Dream Tree," "Little Guide," and "Ordinary Guide," reflecting your learning style and participation.

3. With **Lumens** earned through optional activities that enhance your individuality, you can choose special titles like "Lighthouse of Wisdom" and "Navigator of Thought" to express your unique learning journey.

■ Studying Together: More Fun

1. Pleasant Motivation: See who lit the most lights this week and who became a reliable guide for their friends, providing natural stimulation for one another.

2. A Learning Space Without Rankings: Biyu Note isn't a place to judge who's better. It values ​​the process of acknowledging what you don't know and working together to understand.

Start learning now with Biyu Note, a place that leads to understanding, not memorization.
