KOTTI: The Latest AI-Equipped “Talking Stuffed Toy” Has Arrived in Japan!

KOTTI is the latest desktop AI robot with an adorable plush appearance. Distinct from conventional mechanical robots that use a lot of plastic and metal, KOTTI is characterized by its soft-to-the-touch “costume” appearance. It has attracted a great deal of attention from the Japanese support purchase service “Makuake” due to its high performance.

Product Overview

The greatest feature of this robot is that it is a “hybrid” of two of the world’s best ultra-high-performance AIs: Gemini 2.5 Flash and GPT-5.2. Until now, AI robots have relied on a single engine, which has resulted in slow responses or, conversely, an inability to engage in deep conversations. KOTTI, however, responds to casual, everyday greetings and jokes with the user with the response-oriented Gemini, and to life advice and organizing complex information with the logical GPT.

In addition, this small body is equipped with intelligence that allows it to speak 28 languages, and it can understand and use English, Chinese, and even regional nuances such as the “Kansai dialect” of Japanese. Although the initial setup requires the use of a smartphone, once set up, the robot can interact directly with the user without the need for a smartphone, and even in places where Wi-Fi is not available, it will show emotional reactions such as “snoring” and joy when touched, making it more than just a machine; it is designed to be a “reassuring companion”. The “Wi-Fi” is designed to be more than a machine, but a “reassuring companion.

Summary of key points

We analyzed the appeal of KOTTI from multiple perspectives and organized the key points.

What is KOTTI?

• The next generation of AI plush toys: While on the outside they are soothing plush toys, inside they are intelligent interactive robots directly connected to a state-of-the-art AI server.
• Intelligent Hybrid AI: The industry’s first system that automatically switches between Gemini 2.5 Flash for speed and GPT-5.2 for depth, depending on the situation.
• Global language capabilities: 28 languages are supported, ranging from language learning to intimate conversations in dialects.
• Reliable Japanese localization: Certified for technical compliance (technical standards conformity certification) in accordance with Japan’s Radio Law. Strong safety filters allow children to touch the product with peace of mind.

good point

• Human-like conversational tempo: The use of different types of AI enables smooth conversation with minimal “uh-huh” pauses in thought.
• Unlimited customizability: By entering “prompts” (descriptions) of 400 or more characters, you can design personalities in detail, from strict teachers to pampered pets.
• Unbeatable value for money: Despite being able to directly leverage the API of the latest AI, you can now enjoy unlimited conversations without monthly fees.
• Designed to keep clean: The outer costume can be removed and washed in its entirety. This is designed to ensure a long life together.

points of concern

• Dependence on Wi-Fi environment: Since advanced conversational functions are processed in the cloud, stable 2.4GHz Wi-Fi is required; note that 5GHz is not supported.
• AI-specific “hallucinations “: We will attempt to provide answers based on the latest data, but we cannot guarantee 100% accuracy for very specialized decisions, such as medical or legal.
• Limitations when offline: When not connected to the Internet, the conversational function is deactivated and limited to physical reactions by sensors only.

Users who may be suitable for

• Those who wish to experience the latest AI technology as a “warm presence” rather than a “cold screen”.
• Looking to relieve the loneliness of living alone or looking for a new mood-maker for the family?
• Those who want to practice free talk in a foreign language in the comfort of their own home can take advantage of the 28 languages available.
• Those who are looking for a safe device to educate their children or to talk to the elderly (even those who are not comfortable with IT devices, as the operation is completed only by voice).

rough conclusion

KOTTI is “a smart partner for all generations, combining the ‘intelligence’ of cutting-edge AI with the ‘peace of mind’ of plush toys in the best possible balance.

Frequently Asked Questions (FAQ)

Bulleted summaries

• AI engine: Gemini 2.5 Flash and GPT-5.2.
• Network: Wi-Fi 2.4GHz band is a prerequisite.
• Cell phone use: Used only during setup. A smartphone is not required for daily conversation.
• Customization: Name, personality, and speech style can be changed at will.
• Multilingual support: 28 languages + Japanese dialects (e.g., Kansai dialect).
• Washing and care: Costume is machine washable.
• Safety and Certification: Obtained Japanese domestic technical certification. Multi-layer filter blocks harmful conversations.

Q1. Which AI engine does KOTTI use?

KOTTI analyzes the context of the conversation in real time and instantly switches between Gemini 2.5 Flash and GPT-5.2.

• Gemini 2.5 Flash: Responds at a fast 0.1-second pace to everyday greetings such as “good morning” and “I’m hungry”, jokes, and short exchanges.
• GPT-5.2: It organizes information and answers in depth to questions that require logical thinking and vast knowledge, such as “I’m having trouble at work lately…” or “Tell me how to make a delicious curry. This “two-faced” approach eliminates both the “stress of waiting for a response” and “dissatisfaction with the lack of content” that existed with conventional robots.

Q2. Is an Internet connection required?

Yes, a Wi-Fi connection is essential to enjoy the conversation feature; KOTTI’s “brain” is located on a huge server in the cloud, so real-time communication is required. We especially recommend a Wi-Fi network environment in the 2.4GHz band. We recommend that you check your home router settings, as a dedicated 5GHz band line, which is commonly used in offices, may not be able to connect. The initial setup can be completed in a few minutes by simply following the guide on the smartphone app.

Q3: Do I have to have a smartphone to use the system?

A dedicated iOS/Android application is required for the initial setup (Wi-Fi connection) and the stage of creating a character (agent) of your choice in detail. However, once the “life” is breathed into the KOTTI and the settings are complete, all subsequent conversations, volume adjustments, etc. can be completed with just voice instructions to the KOTTI. As a gift for grandparents, just set it up for them, and they can then enjoy it without a smartphone.

Q4. Will it be an ornament when I am out of the office or in a place without Wi-Fi (offline)?

No, it is not a complete figurine; KOTTI has a built-in physical touch sensor, and when you pet it or pick it up, it will show “emotional reactions” such as making happy noises or snoring sleepily. Although KOTTI cannot engage in deep voice interaction, it still provides the same “sense of security” as a stuffed animal when you are offline.

Q5. Can I change the name of KOTTI to a name of my choice?

Of course. If you tell KOTTI, “Your name is ‘Koko’ from today,” not only through the settings in the application, but also through actual conversation, KOTTI will recognize that name. By calling her by her own special name, you will become more attached to her.

Q6. I am not good with machines. Is it difficult to adjust the volume or check the batteries?

The most important feature of KOTTI is that “everything can be controlled by voice. Just say, “KOTTI, turn the volume to 50%,” or “How much battery power do I have now? KOTTI will answer with its voice and make the necessary adjustments. Since there is no need to operate complicated buttons or the LCD screen, the system is intuitive and easy to use for everyone, from children to the elderly.

Q7: I am worried about dirt on my stuffed animal. Can I wash it?

Yes, it is designed to be kept clean. The outer “costume” can be easily removed and washed by hand or machine in a laundry net. Just be careful not to get the machine parts wet, and you can always keep it looking new and fluffy. However, we recommend natural drying in a well-ventilated place, as the heat from a dryer can damage the fabric.

Q12: Are privacy and security concerns a concern?

KOTTI is designed with privacy protection as a top priority. Although the unit is equipped with a camera, this is used for initial setup and more natural eye contact (facial recognition) with the user; video data is not recorded or stored on a server.

In addition, the product has been certified for technical compliance ( No. 210-256826) for use in Japan, so there is no need to worry about the radio wave law.
