Hi, I'm Elena — I build tools
for how we learn and how we feel.

A high-school student from Shanghai, fascinated by psychology — how people learn, feel, and heal. I design and ship real products that turn ideas from cognitive science into things people can actually use.

Feynman AI

A web app built on the Feynman Technique: you pick a topic and a "student" — a curious child, a peer, or an expert — and teach it out loud to an AI. It asks Socratic questions that expose your gaps, then scores your fluency and subject mastery.

Tether

A mental-wellness web app. You map how you feel on a simple mood pad, and Tether becomes a calm space to steady yourself — paced breathing, grounding, a moment of self-compassion, and a worry journal you can look back on. When you're low, it quietly connects you with others who feel the same, trading small notes of encouragement — some AI-written — so no one rides the hard moments out alone.

CogniCard Academic

A study tool for dense academic reading. Paste — or snap a photo of — a hard text, and CogniCard distills it into clear concept cards, each with a plain-language Feynman analogy, then helps it stick through spaced-repetition review and self-testing. It also includes an ADHD-friendly focus reader that reads aloud in a natural neural voice, highlighting each word.

Working title

A sentence or two about your novel goes here — what it's about, who it follows, and the feeling you want to leave the reader with. Since I'm fascinated by how people think and feel, my fiction tends to live in that same place: inside someone else's head.

About me

I'm Elena — a high-school student in Shanghai. I'm drawn to psychology: how people think, feel, learn, and heal. That curiosity is the thread running through everything I build.

What keeps coming back in my work is one question: how do people actually understand — and feel — something? The Feynman Technique — "if you can teach it simply, you truly understand it" — became the seed for my first product, and the same instinct shaped the others: turning ideas from cognitive science into tools people can hold in their hands.

Away from the screen, I love writing fiction — inventing characters and living inside their heads for a while. To me, storytelling and psychology are chasing the same thing from different directions: what it's really like to be another person.
