About

Hey, I'm Leo 👋

I built strongyes.io as a place to think through code out loud. Solving a problem is one thing. Explaining why it works takes practice.

Pick a problem, write your code, and use Run to check it. The editor is open to everyone.

Meet Coco.

Coco is our AI tutor. She works on your code and asks you to explain your thinking. She never grades or hands over the fix.

Typing with Coco is free when you sign in, up to a daily limit. Talking with her out loud comes with the $79 pack. Anyone can use the editor and Run.

Write your code and explain each step in your own words.
