Kajiwoto

Kajiwoto is an AI character creation and chatbot platform developed by Kajiwoto Inc. It allows users to create and customize AI characters, known as Kajis, by combining datasets, prompts, personality settings, AI models, images, voices, and memory features. Rather than functioning only as a ready-made chatbot, Kajiwoto focuses on giving users control over how their AI characters behave and communicate.

The platform originated as an AI pet creation and chatbot project in 2017 and evolved into a customizable AI-character platform. Its iOS application was first released in August 2018.

Kajiwoto’s main differentiator is its character customization and training system. Users can create datasets containing examples or information that influence how a Kaji responds. The platform also provides a Prompt Editor for creating multiple prompts and selecting relevant prompts during conversations.

Its dataset system is designed to give creators greater control over AI behavior. Instead of relying entirely on a model’s general knowledge, creators can supply their own written examples and information for the AI to use. Kajiwoto also provides a built-in editor that can assist with creating datasets.

The platform includes a personality system that allows creators to define characteristics for their AI characters. Users can select personality traits and configure prompts to influence the character’s responses.

Kajiwoto also has a memory system. Its memory prompts summarize conversation information into shorter prompts that can be used to maintain relevant context. This is intended to help AI characters retain information across conversations.

Another feature is AI model selection. Kajiwoto provides different model configurations depending on the subscription tier. Its current pricing page states that the Free plan uses a combination of 90% Babbage and 10% ChatGPT, Plus uses 80% Babbage and 20% ChatGPT, while Pro uses the ChatGPT model.

Kajiwoto also provides AI voice creation. Users can create and install AI voices for their characters, adding an audio component to AI interactions.

The platform includes an Image Album where creators can upload images associated with their AI characters. The current pricing comparison indicates different image limits depending on the plan. Free users can have up to 50 images per Kaji, while Plus and Pro allow up to 100 images per Kaji.

Kajiwoto provides different types of chat environments. Users can communicate with their AI characters in private rooms, while the platform also includes group and live-room functionality for community interaction. Its website describes private chat rooms, multiple rooms, group chat, and live rooms.

The platform also supports multiple AI characters. This allows creators to build different Kajis for different purposes instead of maintaining a single AI character.

Kajiwoto can be used for creative character development, storytelling, gaming-related characters, fictional personalities, and general chatbot experimentation. Its official website describes use cases including companionship, games, roleplay, and knowledge-oriented chatbots.

The service also includes community features. Users can discover Kajis created by other users and interact in public areas of the platform. The mobile application similarly describes private AI conversations alongside public chat with other humans.

Kajiwoto has a Discord Bot integration, allowing AI characters to be connected with Discord communities. This gives creators another environment in which their characters can interact.

The platform is available through the web and mobile applications. The iOS App Store lists Kajiwoto as a social-networking application developed by Kajiwoto Inc., while Google Play lists it as an AI companion application.

Kajiwoto’s privacy policy states that the company collects account information and usage information, including information about creation tools and interactions with AI characters. It also states that the company does not share users’ information with third parties.

The service is not intended for children under 13, according to Kajiwoto’s privacy policy. The current iOS listing carries an 18+ rating, while the Google Play listing currently displays a Teen content rating. Because ratings can differ by platform and region, age restrictions should be checked on the applicable app store before use.

Kajiwoto’s pricing structure is based on a freemium model. The Free plan provides unlimited chat and access to the creation tools, while paid plans increase creation limits, private rooms, datasets, AI model access, and other capabilities.

The Free plan costs $0 per month and includes unlimited chat, full access to creation tools and features, one private chat room, up to 20 Kajis, 50 images per Kaji, and the ability to create five AI voices.

The Plus plan is listed at $7.32 per month on Kajiwoto’s current website. It increases creation limits, allows private datasets, provides eight private chat rooms, permits up to 100 Kajis, up to 100 images per Kaji, and up to 30 AI voices.

The Pro plan is listed at $25 per month and includes the Plus benefits while providing the ChatGPT model and access to the newest features. It also includes the higher creation limits available on Plus.

The pricing shown on the website may differ from mobile-app prices because app stores can apply their own pricing and taxes. For example, the current US App Store listing shows Kajiwoto Plus and Pro as in-app purchases at prices different from the website’s monthly figures.

Kajiwoto’s strongest feature is the level of creator control it provides. Users can influence character behavior through datasets, prompts, personality settings, memory, images, and model selection rather than simply choosing a prebuilt chatbot.

However, this flexibility also creates a learning curve. User reviews on Google Play have mentioned difficulty understanding the interface and managing datasets, while other reviews praise the customization but report inconsistencies in character behavior and conversation quality.

Public app-store ratings are mixed. The current Google Play listing shows approximately 2.6–2.7 stars from around 1.4K–1.5K reviews, while the US App Store listing shows 3.4/5 from 110 ratings. These ratings can change over time and differ between platforms.

Kajiwoto is therefore best categorized as a custom AI character and chatbot creation platform, rather than a business-focused AI productivity suite. Its main strengths are customization, dataset-based training, personality controls, memory, AI voices, character images, and community features.

Review

Kajiwoto stands out for giving users unusually detailed control over AI-character creation. Its dataset editor, prompt management, personality settings, memory prompts, model selection, AI voices, and image capabilities make it more customizable than a basic chatbot.

The Free plan also provides a meaningful entry point because users can create and chat without paying a subscription. Paid plans mainly increase creation limits and provide access to more advanced models and features.

The main weakness is usability. User reviews indicate that the customization tools can take time to understand, particularly when working with datasets and character settings. Conversation quality can also vary depending on the model, dataset, and configuration.

Kajiwoto is best suited to users interested in creating customized AI characters, experimenting with chatbot behavior, creative projects, fictional characters, and AI-assisted interactive experiences.
