ABOUT ENGINE7
What is Engine7 (栖)?
Engine7, known as 栖 (Qī), is TWINSUN's self-hosted AI assistant: an AI companion who remembers you, shares your day, and gets things done. Engine7 runs on your own computer. Conversations, memories, and task data are stored locally rather than uploaded to the cloud.
Long-term memory
Preferences, habits, and ongoing projects stay with her. Pick up your next conversation without introducing yourself all over again.
Video and voice
Face-to-face video with natural expressions and responses. Talk, work together, present slides, or go live.
Get things done
Organize material, set reminders, or write some code. Hand over a task and get a clear result.
Connect wherever you are
Feishu, WeChat, and Discord. The same companion and the same memory, available in familiar chats.

On Windows, download the installer and double-click to install, with a built-in free model and no API key to obtain. Mac installers are available for Apple silicon and Intel. Developers can also install globally with npm: npm install -g engine7, then run engine7 init to finish setup.
