A self-hosted, browser-based LLM frontend aimed at power users, with rich character cards, prompt control, extensions, and group chats. It runs as a local Node.js server on Windows, macOS, Linux, and Android (via Termux), connecting to many backends — OpenAI, Anthropic, plus local runtimes — using your own keys. Free and AGPL-3.0 licensed with no paid tier.
