Inspiration

Expert coaching is a luxury; consistency is a struggle. We built Aura to be a "Living Agent" that doesn't just wait for you to open an app—it follows you. By leveraging Gemini 3’s deep reasoning and Google Antigravity’s agentic development, we’ve created a coach that stays with you from a deep-dive morning strategy session to a quick WhatsApp nudge in the afternoon.

• Lack of Context: Standard AI bots don't know your specific goals, values, or working style.

• Friction: Opening a separate app to log an expense or check a goal is a barrier to entry.

• Passive Nature: Most apps wait for you to come to them, rather than proactively supporting you.

• High Cost: Human coaching is expensive and inaccessible to the majority.

What it does

Aura bridges the gap between high-level coaching and daily execution. It is a "Coaching Ecosystem" that lives in your pocket and your favorite messaging apps.

Key Innovations:

• Deep Context Onboarding: Aura starts with a "Context Gathering" phase, asking about your top 3 goals, core values, and working style. This data is injected into every interaction, ensuring advice is hyper-personalized.

• Ubiquitous Access (WhatsApp Integration): Aura meets you where you are. You can text or send voice notes to your coach on WhatsApp, and it maintains the same memory and personality as the main app.

• Gemini 3 Live Voice Mode: A low-latency, real-time voice experience that feels like a real phone call with a mentor, featuring a pulsing visualizer and empathetic responses.

• The Knowledge Vault: Pro users can upload PDFs (diet plans, handbooks, etc.), which Aura indexes via Vector Search to provide evidence-based answers from your own documents.

• Dual-Channel Proactive Reminders: Natural language reminders delivered via both Push Notifications and WhatsApp, ensuring you never miss a beat.

How we used Gemini 3

We built Aura's core with Gemini 3 model family to unlock sophisticated agentic behavior.

Reasoning with Thought Signatures: We pass Thought Signatures across conversation turns. This allows the AI to maintain complex coaching "chains of thought" even as the user moves from the mobile app to WhatsApp.

Dynamic Thinking Levels: We utilize thinking_level: high for complex career and financial strategy, and low for fast, snappy WhatsApp check-ins.

Media Intelligence: Using media_resolution_high, our coaches can "read" dense financial statements or fitness plans uploaded to the Knowledge Base with near-human precision.

Gemini Live API: Powers our real-time voice mode, providing a low-latency, empathetic "Real-Time Teacher" experience.

How we built it

  • Model Gemini 3 Pro & Flash (Reasoning, Tools, Media)
  • Real-Time Gemini Live API (Voice)
  • Dev Platform Google Antigravity (Agentic IDE & Verification)
  • Frontend React Native, Expo, Zustand
  • Backend Node & Supabase (PostgreSQL, Edge Functions, RLS)
  • Messaging Wasender (WhatsApp), Expo Push Notifications

Challenges we ran into

  • Context Persistence: Mastering Thought Signatures was a game-changer for keeping coaches "sane" across different platforms (App vs. WhatsApp).

  • Vibe Engineering: Learning to trust Antigravity Artifacts for UI verification saved us dozens of hours in manual QA.

  • Autonomous Nuance: Tuning Gemini 3's function calling to ensure "Nudges" felt helpful, not annoying.

Accomplishments that we're proud of

  • Production Readiness: A full marketplace, subscription-ready (RevenueCat), and multi-channel notification system.

  • True Autonomy: Aura successfully acts as a "Marathon Agent," managing user goals over days without human intervention.

  • Community Core: A platform where users aren't just consumers—they are creators of AI intelligence.

What's next for Aura: The Context-Aware AI Coaching Ecosystem

Wearable Integration: Bringing Aura to smartwatches for even more immediate nudges.

• B2B Offering: Allowing companies to create custom "Corporate Coaches" for employee onboarding and wellness.

• Advanced Analytics: Providing users with long-term "Growth Reports" based on their goal progress and conversation trends.
