llm-group-chat - create multi persona llms and chat with them all in groups

Create AI buddies with distinct roles and prompts, group them into rooms around a topic, and run shared conversations where @mentions can narrow which buddies respond. Inspired by Andrej Karpathy's LLM Council. - Each AI buddy has a role, responsibilities, prompt, and model selection. - Group chats bind a topic to a selected roster of buddies and keep all turns in one shared timeline. - @mentions narrow the responder set; untagged messages fan out to the full room in order. HOW: - Runs entirely in the browser — no sign-in, no backend, nothing leaves your machine unless a buddy sends a prompt to OpenRouter. - Each buddy carries its own system prompt. When a room conversation happens, the room's topic and recent messages are included as context for every reply. - All model requests go through OpenRouter using the API key you provide. Privacy: - Buddies, rooms, and message history are saved in this browser's local storage. Nothing is synced to a server. - Your OpenRouter key is held in memory only for the current tab. It is never written to storage and is cleared on refresh.
