Rikka brings every major AI provider together in a single, polished Android app. Instead of juggling separate apps and browser tabs, you connect your own API keys once and chat with OpenAI, Google Gemini, Anthropic Claude, or any OpenAI-compatible endpoint — all from the same familiar interface. Rikka is built natively in Kotlin with Jetpack Compose, so it feels fast, responsive, and right at home on your Android device.
