What it does
RikkaHub is a chat app for Android phones. You connect it to the AI services you want, such as OpenAI, Google or Anthropic, or any service that works the same way, and switch between them in your conversations.
You can attach images, PDFs and documents, search the web, generate images and video, and use add-ons through MCP (a standard way to connect AI to outside tools). It also has file-based memory, translation and custom agents.
The README warns that many copied versions of the app exist and recommends using the official download to avoid privacy risks.
