The Overengineered LLM Chat Client for Serious Roleplayers

What it does Risuai is a cross-platform desktop and web app that turns multiple LLM APIs into a character roleplay engine. It connects to OpenAI, Claude, Gemini, OpenRouter, and others to run persistent chats with emotion images, group conversations, embedded media, and long-term memory.

The interesting bit Most chat UIs treat model output as read-only; Risuai hands you regex scripts to rewrite it on the fly, plus deep context tools like HypaMemory and SupaMemory to stop your lore from evaporating after a few thousand tokens. The feature set reads like a wishlist from a very specific corner of the internet.

Key highlights

• Supports OpenAI, Claude, Gemini, Ooba, OpenRouter, and more
• Group chats, emotion images, and embedded images/audio/video in conversations
• Lorebooks and long-term memory compression (HypaMemory V2/V3, SupaMemory)
• Regex-based output scripting for custom UI behavior and post-processing
• Three themes: Classic, WaifuLike, and WaifuCut

Caveats

• Project wiki is marked work-in-progress, so documentation trails the feature list

Verdict Grab it if you want a hackable, feature-dense frontend for LLM roleplay or character bots. Look elsewhere if you need a minimal, zero-config chat wrapper with complete docs.
