From HyNote to HyBran

Founder's Letter

Why I'm building HyBran

I grew up in a place where electric lights were not always available. I studied late into the night, took notes by hand, and believed education could change my future.

But there was a cost: my eyesight kept getting worse.

Three years ago, when AI became powerful enough, I started wondering: What if AI could help me study? What if it could take notes for me?

That idea became HyNote.AI.

Today, students use HyNote to record lectures, summarize notes, and learn through quizzes and flashcards.

But I still felt something was missing.

Learning should not always happen on a bright, distracting phone screen. We need a calmer way to read, review, and think.

That is why I am building HyBran.

It is the device I wish I had when I was a student.

A simple tool for deep learning.
A second brain you can carry every day.

A way to protect your focus, your memory, and your eyes.
