Open Muse Chat

Open Muse Chat is an AI chat workspace built for people who use multiple LLMs. Connect to any model available through OpenRouter, search the web, and upload PDFs or images — all in one place. You can customize everything: system prompts, temperature, top‑p, top‑k, max tokens, and reasoning/thinking modes when available. Organize your work with projects and branched conversations so you never lose context or ideas.
