Return Technologies Japan has started offering the official mobile app "Return" for its generative AI chatbot service "wrtn (Return)" on the AppStore. Return is a generative AI chatbot service with 3 million global users, and it offers all its features completely free of charge and without limits.

A new feature, "Trend by AI," has been added, which allows for real-time search using AI as an engine. This feature selects and distributes trending news and trends, and you can use the chatbot feature to ask AI questions or inquiries that arise while reading the news.

The app version also includes the chatbot feature of the web version of Return. This allows you to use AI search for real-time information, large language models like GPT-4 Turbo, and image generation models like Stable DiffusionXL. As with the web version of Return, you can choose the generation model to suit your situation, and users who have pre-registered can also use "Claude 3" (a generative AI model available only in the app), the latest model capable of image recognition.

In addition, the "AI Character Feature" allows you to enjoy conversations with various AI characters through the chatbot function, such as "Kotoha," a friendly friend who encourages fun conversations, or "Tsumuda," a character who is initially cold but actually kindhearted. You can also create your own AI characters and use them with the chatbot function through the "AI Character Maker" feature.

The "Recommended Prompt" feature suggests examples of command statements for generative AI, making it useful for those who find it difficult to write prompts, such as "I want to ask AI something, but I don't know how to ask."

Furthermore, Return will soon be adding OpenAI's latest model, "GPT-4 omni," to both its web version and mobile app version. GPT-4 omni is a new type of AI that can be used in combination with text input as well as voice, images, and videos, announced by OpenAI on May 13 (local time). Return plans to first implement the text input function to provide GPT-4 omni to users quickly. The text functionality of GPT-4 omni provided by OpenAI has improved non-English language processing capabilities, particularly enhanced Japanese language support. In addition, the generation speed has been improved, offering a response speed about twice as fast as GPT-4 Turbo.

Return plans to customize the features for the Japanese market to make using GPT-4 omni more convenient. Return will continue to provide services so that generative AI becomes an even closer and more convenient presence in everyday life.
