Inspiration

We've all experienced the frustration of starting every AI conversation from scratch—typing "Help me be more productive" for the hundredth time, only to receive generic advice that doesn't understand who we are.

What if AI could remember?

What if you could build your own personal advisory board of AI coaches, each with unique expertise and personalities, all understanding your deepest values? What if you could even share your best coaches with others and earn from your creations?

That's the moment BetterOS was born—to democratize AI coaching and create a thriving creator economy around personalized AI.

What it does

BetterOS is your Life Operating System—a platform that combines context-aware AI with a marketplace for custom coaching personalities.

The Orbit Context Engine

Captures your core values, Goals, and current anxieties through a beautiful onboarding interview. This becomes the foundation that every AI interaction is built upon—ensuring every coach truly understands who you are.

Custom AI Coaches

Build your personal advisory board with coaches tailored to different aspects of your life:

  • "The Boss" - Ruthless prioritization and accountability
  • "The Creative" - Expansive brainstorming and ideation
  • "The Stoic" - Emotional processing and resilience
  • Custom coaches - Fitness, finance, relationships, or any domain you choose

Each coach has its own:

  • Unique personality and expertise
  • Custom system prompt and avatar
  • Voice powered by ElevenLabs
  • Shared Orbit context (your values, goals, anxieties)
  • Knowledge aware with RAG

The Coach Marketplace

Transform from user to creator:

  1. Design a specialized coach (e.g., "Startup Advisor" or "Meditation Guide")
  2. Customize personality, expertise, voice, and system prompt
  3. List in the marketplace
  4. Others discover and use your creation

It's the App Store, but for AI personalities.

Voice-First Conversations

Walk and talk with your coaches naturally:

  • Real-time voice conversations with ElevenLabs
  • Natural, human-like interactions

Daily & Weekly Rituals

How we built it

  • TypeScript - Type safety
  • Expo Router - File-based navigation
  • React Context API - Global state management
  • AsyncStorage - Local persistence

Backend & Services

  • Supabase - Auth, Database, Real-time sync
  • Google Gemini - LLM reasoning with custom prompts

Key Features Implementation

Coach Creation System:

  • Name, tagline, and personality traits
  • Expertise areas and communication style
  • Custom system prompts for specialized knowledge
  • Avatar colors and ElevenLabs voice selection
  • Marketplace listing
  • Automatic Orbit context inheritance

Challenges we ran into

1. Marketplace Architecture

Building a system where coaches can be both private (personal use) and public (marketplace listings) while maintaining proper ownership, and usage tracking required careful database design and RLS policies.

2. Multi-Coach Context Management

Ensuring every coach—whether created by you or installed from the marketplace—had access to your Orbit context while maintaining their unique personalities required sophisticated prompt engineering.

3. Real-time Marketplace Sync

Making marketplace listings update in real-time as creators publish new coaches, users leave reviews, and popularity metrics change, all while maintaining performance, was complex.

4. Voice Integration Per Coach

Integrating ElevenLabs with coach-specific voice settings, handling voice call state management across marketplace coaches, and ensuring smooth transitions required careful architecture.

Accomplishments that we're proud of

The Coach Marketplace

Transforms BetterOS from an app into a platform. Users become creators, Creating their expertise in effective AI coaches. It's the first true creator economy for AI personalities.

Seamless Integration

Try a "Fitness Coach" from the marketplace, and it instantly knows your core value of "Health First" and your 5-year goal of running a marathon. Context + Marketplace = Magic.

Real-time Synchronization

A creator publishes a coach → it instantly appears in the marketplace for all users. Someone leaves a review → the creator sees it immediately.

Beautiful Simplicity

In under two minutes, users can create a fully customized AI coach with personality, expertise, voice, and marketplace listing—all automatically context-aware through our Orbit.

Everyone Wins

  • Users get access to expert-crafted coaches
  • Creators earn from their expertise
  • Platform grows through community contributions
