The modern wellness paradox: People know they should eat better, sleep more, and exercise regularly - but traditional health apps feel like another chore. Meanwhile, workplace stress is at an all-time high, and "hustle culture" promotes burnout as a badge of honor.
Oystraz solves this by:
- Gamifying health - Your real-world choices power a virtual character
- Providing a safe stress outlet - Prank your virtual octopus boss instead of real confrontation
- Anti-hustle philosophy - Our AI companion Pearl actively discourages overwork
- Making tracking fun - Ocean theme, pixel art, and playful interactions
| Google Product | How We Use It |
|---|---|
| Gemini 2.0 Flash | Powers Pearl, our AI health companion with personality-driven responses, food science knowledge, and personalized health coaching |
| Google Veo 3.1 | Created the "Seal Pranks Octopus" video animation that plays during overtime/stress relief events |
| Google AI Studio | Used for demo design, prompt engineering, and development assistance |
- Extended Context Memory - Pearl remembers your health history across conversations
- Advanced Reasoning - Analyzes USDA nutritional data and generates personalized insights
- Personality Engineering - System instructions create Pearl's unique anti-hustle, food-enthusiast personality
