What is Kajiwoto and what does it offer?

Kajiwoto is a decentralized AI character platform where the core value proposition is user-owned datasets. Unlike competitors that provide a single black-box model, Kajiwoto allows users to build "Kojis"—AI souls—using custom data, personality traits, and specific knowledge bases. It separates itself by offering a marketplace for datasets, allowing creators to monetize the "brains" of their AI. If you are looking for a platform where you control the underlying logic rather than just a chat prompt, Kajiwoto is a primary contender.

What LLM/s does Kajiwoto use?

The platform utilizes a multi-model approach. By default, it uses Kajiwoto’s in-house models, which are optimized for character consistency and roleplay.

• External APIs: Users can toggle between various high-tier models including GPT-4o and Claude 3.5 (requiring Kaji Gold/Credits).
• Intelligence Stability: Character adherence is generally high because the AI relies on the Koji's specific dataset. However, users report that the in-house models occasionally lean into repetitive phrasing during long-form roleplay, though they avoid the "purple prose" common in heavily RLHF-tuned models like Claude.

Does Kajiwoto have image/video generation?

Yes, Kajiwoto integrates Kaji-Image, a tool primarily used for generating character avatars and scene illustrations.

• Capabilities: It supports generating images in-chat to visualize the roleplay.
• Video: Video generation is currently rudimentary, focusing on small animations or "talking head" styles for Kojis rather than full cinematic scene generation.

Does Kajiwoto use my data and can I opt out?

Kajiwoto stores chat logs to maintain context and history for your specific Kojis.

• Training: Public Kojis are built on user-contributed datasets. However, private chats are generally not used to train the global base models.
• Opt-Out: Users can set Kojis to Private, which restricts data visibility. Privacy-conscious users should note that while they don't explicitly sell "chat data," using external models (like OpenAI or Anthropic) subjects that data to those third-party providers' terms.

What tools are available for advanced roleplayers?

Kajiwoto offers a robust suite for power users:

• Lorebooks/World Info: Handled via the "Dataset" system where you can upload specific world-building facts.
• Persona Memory: Highly granular; you can define how the Koji perceives the user.
• Chat Branching: Supports message editing and regeneration.
• Import/Export: Allows exporting Koji datasets, though it is not a 1:1 format with "Character Cards" (V2) used by SillyTavern.
• OOC Commands: Supported via bracketed text, though model responsiveness varies.

What is the real cost of using this tool?

The pricing is split between Subscriptions and Kaji Gold.

• Free Tier: Significant throttling on response speed and limited access to high-tier models.
• Plus/Pro Tiers: Monthly fees (approx. $8–$25) provide faster response times and a monthly Gold allowance.
• Hidden Costs: Using "Premium" models (GPT-4o, etc.) drains Kaji Gold per message. If you chat extensively with high-tier models, the cost can exceed $30/month.

What are the most common complaints from the Reddit community?

Recent sentiment analysis from r/Kajiwoto and r/CharacterAI_Alternatives highlights several friction points:

1. UI/UX Complexity: Many users find the interface "clunky" and unintuitive compared to modern streamlined apps. Source
2. Credit Drain: Complaints frequently surface regarding how quickly Kaji Gold is consumed when using non-native models. Source
3. Model Degradation: Some long-term users claim the base in-house models have become "stiff" or less creative after recent updates to balance server load.

FAQ

Q: Is Kajiwoto completely unfiltered? A: Yes, the platform allows for NSFW content, provided the individual Koji's dataset and the user's settings permit it.

Q: Can I use my own API key? A: No, Kajiwoto typically requires you to purchase their internal currency (Gold) to access external models rather than inputting your own OpenRouter or OpenAI keys.

Q: Does Kajiwoto have a mobile app? A: Yes, it is available on both iOS and Android, though the web version offers more granular control over dataset editing.
