RPClient is a local-first AI role-playing chat client for Android. It helps you manage character cards, lorebooks, one-on-one chats, group chats, prompt presets, summary memory, and regex scripts directly on your device. Chat histories, characters, lorebooks, and app settings are stored locally by default. RPClient does not provide model services. You choose and configure your own model provider, including OpenAI-compatible APIs, Gemini, Anthropic Messages, DeepSeek, OpenRouter, or a custom endpoint. Model requests are sent directly to the provider configured by you. Features include: - Character Card V1/V2 JSON and PNG import - Character Card V2 JSON and PNG export - SillyTavern-style lorebook import and export - One-on-one and multi-character group chats - Streaming responses, regeneration, continuation, and impersonation - Long-term summary memory - Prompt presets, macro expansion, prompt inspection, and token budgeting - Global, preset, and character-scoped regex scripts - Local request log debugging mode - Material 3 UI with multiple interface languages The project is under active development. Back up important cards, lorebooks, and chats before upgrading.
