About PeeTeeAI
AI Personal Trainer
for Humanity
We believe every human being has untapped potential, and AI can be the key to unlocking it -- not by replacing human effort, but by amplifying it in deeply personalized ways.
Founder Story
Why HumanOS Exists
Founded by Quijote (Hai Hoang) in 2024, PeeTeeAI was born from a deeply personal conviction: the next 20 years will bring more change than the last century, and most people will not have the tools to keep up -- not because they lack potential, but because they lack the right support.
After 20+ years in software engineering, Quijote saw firsthand how technology could either empower or overwhelm people. AI was transforming industries, but almost no one was using it to help everyday humans become stronger, sharper, and more resilient.
The idea was audacious: build an AI personal trainer that covers every dimension of human development -- breathing, memory, habits, focus, emotional intelligence, and creativity. Not a single monolithic app, but an ecosystem of specialized tools that work together, adapt to each individual, and are grounded in real science.
That ecosystem is HumanOS. And we are just getting started.
Our Journey
Company Timeline
Founded
Quijote founds PeeTeeAI with a bold vision: build an AI personal trainer for every dimension of human potential.
First Apps Launch
BreathMaster AI and MemoryForge go live, validating the core thesis that AI coaching can drive real behavioral change.
6-App Ecosystem
HumanOS reaches full ecosystem status with 6 interconnected apps serving 10,000+ users across breathing, memory, habits, focus, emotional intelligence, and creativity.

Our Mission
To build AI-powered tools that serve as a personal trainer for every dimension of human development -- cognitive, physical, emotional, and creative. We make world-class self-improvement accessible to everyone, regardless of background, culture, or starting point.
Our Vision
A world where every human has an AI-powered ally for personal growth. Where technology amplifies human potential instead of replacing it. Where the tools for becoming your best self are as accessible as the tools for entertainment and distraction.
Our Values
What We Stand For
Human-First
Technology serves humans, not the other way around. Every feature we build starts with the question: does this genuinely help someone grow?
Inclusive by Design
Built for the full diversity of humanity. Our AI adapts to different cultures, languages, backgrounds, and biological profiles.
Evidence-Based
Every feature is grounded in peer-reviewed research from neuroscience, behavioral psychology, and exercise physiology.
Open & Transparent
Our core algorithms are open source. We share our research and welcome collaboration from the global community.
Long-Term Thinking
We optimize for 20-year impact, not quarterly metrics. Sustainable human growth requires patience and vision.
Empowering
We build autonomy, not dependency. Our tools teach you to be better, then step aside as you grow stronger.
Research
Built on Peer-Reviewed Science
Every feature in the HumanOS ecosystem is informed by established research in breathing science, cognitive training, and behavioral psychology.
Breathing Science
Our breathing exercises are built on decades of respiratory physiology research, including Buteyko, Wim Hof, and pranayama studies.
Cognitive Training
MemoryForge leverages spaced repetition research and the N-Back paradigm, validated across dozens of peer-reviewed studies.
Behavioral Psychology
HabitOS and FocusFlow are grounded in BJ Fogg's behavior model, implementation intentions, and self-determination theory.
