Architecture

The project is built according to the principles of Clean Architecture and divided into layers:

• Presentation (UI, Activity, Fragments, ViewModels)
• Domain (UseCases, Entities, Repository interfaces)
• Data (Room, Retrofit, Repositories, Mappers)
• DI (Component, Modules, Scope, Qualifiers)

The MVVM pattern is implemented (ViewModel + Flow).
Dependency Injection is handled via Hilt.

Tech Stack

• Kotlin, Android SDK, Coroutines, Flow, ViewBinding
• Room (storing chat history and favorite AI models)
• Retrofit2 (network requests to the OpenRouter API)
• Hilt (dependency injection)
• Markwon (markdown rendering)
