📋 Overview
Habit Coach AI is an AI-powered accountability and habit coaching app. It doesn't just track habits — it coaches. The AI adapts to each user's personality, learns their patterns of failure and success, and delivers the right nudge at the right time. Think of it as a personal coach that knows you, is always available, and never judges — but also never lets you off the hook.
💡 Origin Story
This started with a personal experiment: I hired a random guy in Ukraine to call me every night at 10pm and ask about my habits. No expertise, no coaching framework — just a human checking in consistently. It was transformative. The accountability of knowing someone would ask "did you do it?" changed everything. The question became: could AI replicate that simple, persistent, personal accountability at scale? Turns out, yes — and it can do things a human can't, like analyzing your patterns across months and adapting its approach based on what actually works for you.
🛠 Tech Stack
🧠 Technical Challenges
The hardest problem wasn't building the app — it was making AI feel like a real coach, not a chatbot.
Users would disengage after a few days because the AI felt generic. Coaching that sounds good on paper can feel hollow in practice.
Built a system where the AI adapts its coaching style to each user — tough love for some, gentle encouragement for others. It maintains long-term memory of each user's journey, referencing past wins and struggles. Engagement jumped once users felt the AI actually "knew" them.
🎯 Role
Founded and built solo for the first year — product vision, user research, and initial development. Then partnered with Nino for a year, where I focused on business, product, and growth while we built together. Now solo again post-split, continuing to develop and iterate.
✨ Key Results
- Personalized coaching that adapts its tone and strategy per user
- Origin story (the Ukrainian phone call experiment) became the product's core narrative
- Users like James (64, 76 sessions) and Jared (lost 21 lbs and got a job) proving the model works
