Kajiwoto

Kajiwoto lets users build their own AI companion from scratch — training it with custom prompts and datasets — then chat with it privately or bring it into public community rooms, blending AI companionship with social/community features.

Core Capabilities

Custom Character Training Users define a "Kaji" using prompts, memory seeds, and personality datasets, with a choice of underlying AI models ranging from fine-tuned open-source models to models tuned for distinct personality styles.

Layered Memory System Kajis save short-term memories during a conversation and periodically summarize them into long-term memory, letting companions reference past context over extended relationships.

Defined Relationship Types Users can explicitly set the nature of a companion relationship — friend, enemy, romantic partner, or spouse — which shapes how the Kaji responds.

Community & Social Rooms Beyond private chat, users can go live in public rooms to meet other users and share or discover community-created Kajis, adding a social layer most single-player companion apps lack.

Positioning

Competes with Character.ai and Janitor AI (both in this catalog) in custom-companion-chat, but differentiates with its explicit relationship-type framework, layered memory summarization, and a stronger community/social layer (public chat rooms, Discord presence).

Pricing

Freemium — most core features usable for free. Plus subscriptions start around $4.99/month for expanded limits and model access, with a higher Pro tier around $25/month unlocking advanced models and priority features.
