**Friday Assistant** is a next-generation, voice-activated Personal AI companion built with **Flutter**. Designed with a "Sci-Fi First" philosophy, it combines state-of-the-art Large Language Models (LLMs) with a premium, immersive user interface featuring holographic aesthetics, reactive animations, and proactive intelligence.

Unlike standard chatbots, Friday possesses **Long-Term Memory**, **Real-Time Web Access**, and a **Proactive Sentinel Mode** that watches out for you even when the app is in the background.

| Feature | Benefit | 
|---|---|
| Voice-first interface | Hands-free operation | 
| Long-term memory | Remembers your preferences across sessions | 
| Proactive notifications | Alerts you before conflicts arise | 
| Tool integration | Opens apps, sends messages, navigates | 
| Multi-platform | Android, iOS, Web, Desktop | 
| Privacy-focused | Your data stays in your Supabase vault | 

- **The Friday Orb:** A central, living core that reacts to voice amplitude, pulses when thinking, and transforms based on AI state (Idle, Listening, Processing, Speaking)
- **Holographic Aesthetics:** Glassmorphism effects, neon gradients, and dynamic Particle Field backgrounds
- **Neural HUD:** Real-time system status display with Neural Link indicator and active Memory Node count
- **Immersive Feedback:** Haptic feedback and distinct sound effects for all interactions

- **FridayBrainService:** Powered by**Groq (Llama 3.3 70B)** for lightning-fast inference and complex reasoning
- **Agentic Workflow:** Visualized thought process phases: Thinking -> Searching Web -> Accessing Memory -> Synthesizing
- **Memory Auditor:** Autonomous sub-agent that verifies information against existing memory to prevent conflicts
- **Tool Integration:**  - **web_search:** Real-time data fetching (Weather, News, Stock Prices)
  - **save_memory/search_memory:** Supabase Vault integration for personal facts and preferences

- **Background Nudges:** Scheduled background checks on schedule, weather, and environment
- **Contextual Awareness:** Intelligent notifications (e.g., "Outdoor meeting at 3 PM with forecasted rain - take an umbrella")
- **Manual Diagnostics:** Trigger instant Sentinel Check for immediate analysis

- **Multilingual Support:** English, French, German, Spanish, and Hindi
- **Real-Time Transcription:** Seamless speech-to-text dictation
- **Natural Voice:** High-quality Text-to-Speech response system

- **Local Processing:** Initial reasoning via Groq's high-speed inference
- **Encrypted Vault:** Personal memories in private Supabase instance with Row Level Security (RLS)
- **Minimal Footprint:** No audio data storage; STT processed and discarded in real-time

| Component | Technology | 
|---|---|
| **Framework** | Flutter (Dart) | 
| **AI Backend** | Groq API (Llama 3.3 70B) | 
| **Database** | Supabase (PostgreSQL) | 
| **State Management** | Native setState & Streams | 
| **Animations** | flutter_animate & Custom Painters | 
| **Voice** | speech_to_text & flutter_tts | 
| **Background Tasks** | workmanager | 
| **Notifications** | flutter_local_notifications |
