Solace

Solace is an Android native AI companion client, developed based on the open-source project RikkaHub, and follows AGPL-3.0. It fully retains the capabilities of multiple Providers, MCP, Workspace, online search, local backup, embedded Web, message branching, assistant memory, and SillyTavern character cards. The operation interface is redesigned with a warm companion style for the Home hub, Agent partner, and Profile capability pages. It supports OpenAI/Anthropic/Gemini compatible protocols, multimodal attachments, Markdown rendering, TTS/ASR, and custom assistants. It is suitable for Android AI dialogue scenarios that require local control, scalability, and a stronger sense of companionship. The technology stack includes Kotlin, Jetpack Compose, Koin, and Navigation 3, targeting individuals and self-built APIs.
