How to Use Kajiwoto in 2026: Step-by-Step Guide
Community-driven platform for creating and chatting with custom AI companions ("Kajis"), featuring selectable AI models, long-term memory, and definable relationship dynamics.
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.

Getting Started
Create Your Account
Visit https://kajiwoto.ai and sign up for a freemium account. You'll need an email address to register. A free tier is available — you can upgrade later for more features.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Kajiwoto supports custom-character-creation, long-term-memory, relationship-roleplay, model-selection — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Kajiwoto what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
