utsuwa

Utsuwa is an open-source alternative to Grok Companion. This is a platform where you can have a virtual AI waifu that learns and grows with you, bundled with optional mechanics inspired by Japanese dating sim games. Maintained by The-Lab-by-Ordinary-Company on GitHub, where it has earned 40 stars from the community.

It's actively developed around ai, ai-companion, ai-waifu, and is a solid reference for anyone building with these tools.
