I already had an OpenAI API key, so I used it without a subscription, entering the API key and selecting gpt-4o in the setting window ([setting] > [ChatGPT]).



It is a very fun conversation, and I especially liked the emotional expression of the character.



It is interesting to note that the following three parameters can be used to adjust the character's personality. (But you have to pay for this.)

“Humanity“ (Cute devil vs Angel)

“Vibe“ (Shy vs Cheerful)

“Phrasing“ (Friendly vs Polite)



The app supports multilingual conversation, so you may have fun practicing foreign language conversation.





"AR Chat Friend" offers a unique AI voice interaction experience with AR characters. Here are some of its key features:



- Rich Emotional Interactions:

Characters communicate with expressive emotional actions, triggering 3D effects based on their emotions.



- Flexible usage scenarios:

You can use your own OpenAI API key, or subscribe to eliminate the need for an API key.



- Customizable Personas:

Users can edit characters' personas (e.g., cute devil, angel) and change their voices.



- Multilingual Support:

The app supports conversations in Japanese, English, German, French, and Korean, making it a great tool for language learning.



- VRoid Hub Integration:

Users can incorporate characters from VRoid Hub, a service by pixiv. (A pixiv account is required.)
