### 1/5 — The worst

*2024-08-10*

This app is horrible. I can’t even use it.

**Developer response:** I am sorry to hear that you were not able to use it. It would be helpful if you could tell me the name of the model and what exactly happened. Thank you in advance.

## Version history (last 5 releases)

### 2.0.3 — 2024-05-21

When using an OpenAI API key, the latest AI model without "preview" in the name is used by default. As of May 21, "gpt-4o-test-shared" is used. However, there seems to be a problem with "gpt-4o-test-shared", so I have modified it so that AI models with "preview" or "test" in their names are not used by default. In addition, a selection dialog is now displayed when determining the default AI model.

### 2.0.2 — 2024-05-16

- Subscriptions are now available. (In the previous version, an API key for OpenAI was required, but this is no longer necessary for subscription use.)
- Emotional expressions with 3D effects have been implemented.
- The ability to easily set a character's persona with a slider control has been added. (Paid function)
- A new function to assist in speaking in a foreign language has been added. (Paid function)
