Aiyo

Aiyo is an open-source AI chat application for Android in the AI Tools category. It provides a simple client for chatting with models available through OpenRouter. The app is intended for Android users who want to choose among many AI models while supplying their own OpenRouter API key.

Aiyo lets users chat with any model of their choice through the available OpenRouter connections. It provides access to more than 500 models on OpenRouter. Supported capabilities include reasoning, web search, and chat history. These features allow conversations to be conducted with different model options while retaining access to previous chats within the app.

The app communicates with OpenRouter API endpoints using the API key provided by the user. Aiyo itself does not collect information or call data. However, Aiyo does not take responsibility for information that may be collected by OpenRouter or by the model provider.

Aiyo requires Android 7, also known as API level 24, or a later version, as well as an OpenRouter API key. Its open-source license allows users to review the source code, contribute to the project, or build the application themselves from the code available on GitHub. On MirrorNest, the official Android build is mirrored directly on the service’s own storage and scanned for malware before publication. This distribution places Aiyo within MirrorNest’s Android software catalog while preserving its open-source status and its requirement for an OpenRouter key.
