Kajiwoto

Kajiwoto is a uniquely community-focused AI companion platform where users create, train, and interact with AI characters called Kajis. What makes it special is the training system — users can build characters using custom datasets, prompts, and AI model selection, essentially training their own miniature language models with specific personalities and knowledge.

The platform supports private chats and public rooms for meeting other users, character adoption (using other users' trained characters), and Discord integration. With 100K+ downloads, Kajiwoto has cultivated a niche community of AI hobbyists who enjoy the technical aspect of training characters alongside the social experience of sharing and discovering them.

Kajiwoto is free to use, relying on community engagement rather than aggressive monetization. Content moderation varies by character since the library is community-created. The platform is available on web, iOS, Android, and Discord. Best for technically curious users who want to understand and participate in AI character training rather than just consuming pre-built companions.
