## What is Cornerman?

Cornerman is your AI coach and mentor: someone in your corner who keeps you accountable to your goals and checks in when it matters.

PICK THE COACH THAT PUSHES YOU THE RIGHT WAY
• Drill Sergeant: no excuses, straight talk.
• The Sage: calm, long-view guidance, one wise step at a time.
• The Champion: high-energy hype for every rep.
• The Operator: run your life like a system.

HOW IT WORKS
1. Tell your coach what you want to change.
2. Get a clear next step, not a lecture.
3. Your coach checks in so you lock in and keep your momentum.

BUILT FOR
• People who start strong and fall off
• Anyone building discipline, willpower and better habits
• Beating procrastination, overthinking and low motivation
