Alternative to:

RisuAI is an AI roleplay client for people who want to create characters and fictional worlds, then develop stories through conversation. It supports chats with individual characters or groups.

Character media: Emotion images reflect character expressions, and images, audio and video can appear in conversations or backgrounds.
Story context: Lorebooks hold world and character information, while memory compression and context management help maintain longer conversations.
Prompt control: Custom templates, conditions and variables let you shape character responses; plugins add features or providers, and regex scripts can modify model output and chat displays.
Translation and voice: Automatic translation handles incoming and outgoing text, and text-to-speech can read replies aloud.
Character sharing: RisuRealm is a separate site for publishing and finding characters and fictional worlds.

RisuAI runs on Windows, macOS, Linux, Android and in a browser. You can self-host the web app with Docker. Supported backends include OpenAI, Claude, Gemini, DeepInfra, OpenRouter and Ooba, with switching between providers. Cloud backends receive your chat requests even when you host the interface yourself. The client is open source under GPL-3.0.
