Ginly AI - Hackathon Project Story
Inspiration
The inspiration for Ginly AI came from witnessing the explosive growth of AI-generated content on social media platforms like TikTok, Instagram, and YouTube. We noticed that while AI tools were becoming incredibly powerful, they remained fragmented, expensive, and difficult for everyday users to access. Content creators were jumping between multiple platforms, paying separate subscriptions, and struggling with complex interfaces just to create engaging visual content.
We asked ourselves: "What if we could democratize AI content creation by bringing multiple cutting-edge AI models into one seamless, mobile-first platform?"
The vision was clear - create an all-in-one AI content generation app that would empower anyone, regardless of technical expertise, to create stunning images and videos with just a few taps.
What it does
Ginly AI is a comprehensive mobile application that transforms text prompts and user photos into stunning visual content using state-of-the-art AI models. The app offers four main content creation modes:
Realtime AI Image Generation
- Lightning-fast image creation using FLUX.1-schnell model via Together.AI
- Real-time preview as users type their prompts
- Consistent seed system for iterative improvements
- Base64 optimization for instant display
Advanced Text-to-Image
- Multiple AI models including FLUX.1-dev, FLUX.1-schnell, and Stable Diffusion
- Customizable parameters: aspect ratios, quality settings, negative prompts
- Batch generation capabilities
- High-resolution outputs up to 1024x1024
AI Video Generation
- Image-to-video conversion using Pollo.ai and Pixverse integration
- Template-based effects with 100+ pre-built animations
- Custom duration control (2-10 seconds)
- Multiple quality options (540p, 720p, 1080p)
Template Effects
- Viral social media effects like "Kiss Me AI", "Hug", "My Girlfriends"
- Multi-language support (11 languages including Turkish, English, Arabic, Chinese)
- Trend-based categorization with real-time updates
- One-tap generation with pre-optimized prompts
Smart Features
- Credit-based monetization with three subscription tiers
- Firebase-powered backend with real-time sync
- Google & Apple Sign-In integration
- Comprehensive media library with sharing capabilities
- Webhook-optimized video processing for efficient resource usage
How we built it
Frontend Architecture
- Flutter Framework for cross-platform mobile development
- BLoC Pattern for robust state management
- Clean Architecture with separation of concerns
- Dependency Injection using GetIt for scalable code structure
AI Integration Strategy
We integrated multiple AI services to provide the best-in-class generation capabilities:
- Together.AI for lightning-fast realtime image generation
- Fal.AI for advanced image models with high-quality outputs
- Pollo.AI for professional video generation and effects
Backend Infrastructure
- Firebase Firestore for user data and content metadata
- Firebase Storage for media file management
- Firebase Functions for webhook processing and credit management
- RevenueCat for subscription management across platforms
Key Technical Implementations
Real-time Image Generation
We implemented a sophisticated real-time generation system that responds to user input instantly, using optimized API calls and intelligent caching mechanisms for seamless user experience.
Credit System Implementation
We built a sophisticated credit management system:
- Dynamic credit requirements per feature type
- Automatic deduction before API calls
- Rollback mechanism for failed generations
- Real-time credit tracking across all user sessions
Webhook Optimization
Instead of polling APIs, we implemented webhook listeners for efficient video processing, eliminating unnecessary server requests and providing instant notifications when content generation is complete.
Internationalization
- 11 language support with Flutter's intl package
- Dynamic content localization for templates and effects
- RTL language support for Arabic markets
Challenges we ran into
1. Multi-AI Service Coordination
Challenge: Each AI service (Together.AI, Fal.AI, Pollo.AI) had different API structures, rate limits, and response formats.
Solution: Created a unified abstraction layer with standardized models and error handling that seamlessly manages different AI providers behind a single interface.
2. Real-time Performance Optimization
Challenge: Users expected instant feedback while typing prompts, but AI generation takes 2-5 seconds.
Solution:
- Implemented debounced input handling to reduce unnecessary API calls
- Used base64 image caching for instant display
- Created progressive loading states with shimmer effects
3. Credit System Complexity
Challenge: Managing credits across multiple AI services with different costs while preventing double-charging and handling failures.
Solution: Implemented atomic transactions with Firebase that ensure credit consistency across all operations, preventing double-charging and handling service failures gracefully.
4. Video Processing Scalability
Challenge: Video generation can take 30-60 seconds, causing timeout issues and poor user experience.
Solution: Webhook-based architecture that eliminated polling:
- Generate video → Get job ID → Return immediately
- Webhook notifies completion → Update UI automatically
- 90% reduction in unnecessary API calls
5. Cross-Platform Subscription Management
Challenge: Handling iOS App Store and Google Play Store subscriptions with different validation systems.
Solution: Integrated RevenueCat for unified subscription management across platforms.
