-1. **Authentication**: Sign in with Google or email through Firebase Auth
-2. **Speech Mode**: Tap the microphone to start real-time speech transcription and fact-checking
-3. **Image Mode**: Upload an image or provide a URL to extract and verify text claims
-4. **Debate Mode**: Enable continuous speech recognition for live debate fact-checking
-5. **View Results**: Check claim ratings, explanations, and source citations
-
 ## Code Explanation
 
-### Perplexity Sonar API Integration
-
-The app integrates with Perplexity's Sonar API in two main ways:
+* Frontend: Flutter with BLoC pattern for state management targeting iOS, Android, and Web
+* Backend: Firebase (Firestore, Authentication) for user data and chat history persistence  
+* Speech Processing: speech_to_text package for real-time audio transcription
+* API Integration: Custom Dart client calling Perplexity Sonar API with structured prompts
+* Image Processing: Built-in image picker with base64 encoding for multimodal analysis
+* Data Architecture: Firestore collections per user with subcollections for debates, speeches, and images
 
-1. **Debate Fact‑Checking**  
-   - Stream 5‑second audio chunks → transcribe → send `textSnippet` to Sonar  
-   - Parse JSON response for `{ claim, rating, explanation, sources }`
+## Open Source SDKs
 
-2. **Image Analysis**  
-   - Upload or URL‑point to image → Sonar extracts on‑image text → verify each claim
-
-```dart
-final client = PerplexityClient(apiKey: env.SONAR_API_KEY);
-final response = await client.analyzeClaim(textSnippet);
-print('Rating: ${response.rating}, Confidence: ${response.confidence}');
-```
+Built two reusable packages for the Flutter community:
+- **[perplexity_dart](https://pub.dev/packages/perplexity_dart)** - Core Dart SDK for Perplexity API
+- **[perplexity_flutter](https://pub.dev/packages/perplexity_flutter)** - Flutter widgets and BLoC integration
 
-The app processes audio in real-time, transcribes it using Flutter's speech-to-text package, and sends each snippet to the Sonar API for immediate fact verification with source citations.
-
-### Custom SDKs Used
-
-This project uses custom-built Perplexity API SDKs developed specifically for this hackathon:
-- **perplexity_dart** - Core Dart SDK ([pub.dev](https://pub.dev/packages/perplexity_dart), [docs](perplexity-flutter))
-- **perplexity_flutter** - Flutter widgets and utilities ([pub.dev](https://pub.dev/packages/perplexity_flutter), [docs](perplexity-flutter))

-## Limitations
-
-- Speech recognition accuracy depends on audio quality and background noise
-- Fact-checking is limited to claims that can be verified through available online sources
-- Image text extraction quality varies based on image resolution and text clarity
-- Real-time processing may experience latency depending on network connectivity
-- Cross-platform compatibility is still being tested for macOS and Windows
-- API rate limits may affect continuous usage in high-volume scenarios
-- Android microphone access permissions need to be added for long duration listening
