🛥 Stream Chat SDK

ChatGPT Android is built with Stream Chat SDK for Compose to implement messaging systems. If you’re interested in adding powerful In-App Messaging to your app, check out the Android Chat Messaging Tutorial!

📲 Download APK

Go to the Releases to download the latest APK.

Note: This app is using unofficial APIs, so normally it takes 10~15 seconds to get the entire response and the app might not work as your expected anytime.

🏛️ Architecture

ChatGPT Android follows the Google's official architecture guidance.


ChatGPT Android was built with Guide to app architecture, so it would be a great sample to show how the architecture works in real-world projects.

The overall architecture is composed of two layers; UI Layer and the data layer. Each layer has dedicated components and they each have different responsibilities. The arrow means the component has a dependency on the target component following its direction.

Architecture Overview


Each layer has different responsibilities below. Basically, they follow unidirectional event/data flow.

UI Layer


The UI Layer consists of UI elements like buttons, menus, tabs that could interact with users and ViewModel that holds app states and restores data when configuration changes.

Data Layer


The data Layer consists of repositories, which include business logic, such as querying data from the local database and requesting remote data from the network. It is implemented as an offline-first source of business logic and follows the single source of truth principle.

For more information about the overall architecture, check out Build a Real-Time WhatsApp Clone With Jetpack Compose.



ChatGPT Android adopted modularization strategies below:

  • Reusability: Modulizing reusable codes properly enable opportunities for code sharing and limits code accessibility in other modules at the same time.

  • Parallel Building: Each module can be run in parallel and it reduces the build time.

  • Decentralized focusing: Each developer team can assign their dedicated module and they can focus on their own modules.

💯 MAD Score
