About Rikkahub
Rikkahub is a native desktop client for chatting with large language models, rebuilt for PC from the Android edition of Rikkahub. It supports multiple providers including OpenAI, Anthropic, Google Gemini, and any OpenAI-compatible endpoint, along with local models through Ollama and LM Studio. Conversations accept multimodal input, and the app provides MCP support, web search, image generation, and text-to-speech or speech recognition. It stores everything locally, requires no cloud account, and includes no telemetry.
