# Welcome to Rikka — Your Android AI Chat Application

> Rikka is a native Android app that unifies OpenAI, Google Gemini, Anthropic Claude, and any OpenAI-compatible provider in one beautiful interface.

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.

## Why Rikka?

Rikka was designed around one idea: you should own your AI experience. You bring your own API keys, choose your own models, and keep your conversations private. There are no subscriptions, no middlemen, and no lock-in.
