### 5/5 — I love it!!!

*2024-01-12*

The only app in the App Store that permits API key usage without robbing you of your hard earned money.

### 4/5 — Simple. Great. Effective.

*2023-06-21*

A very simple yet effective app which allows you to integrate Chat GPT in your everyday text writing or processing. Honestly it is great and even though I’ve tried a LOT of chat Gpt apps this one may not have so many bells and whistles, but that’s what makes it really good. You can customize it with your preset conversations or characters to fit any scenario. 

The keyboard extension currently seems to have a bug. No matter what text I select, the text that will be sent for the app to process is not all of it (it seems it only grabs the first and last sentence). When this is fixed I’ll update my review. 

Also, I wish we had the option of choosing the new 3.5 model with 16k context.

### 4/5 — 更新后不停的闪退

更新后不停的闪退

**Developer response:** 感谢反馈🙏最新版已修复

### 5/5 — Very good.

*2023-03-31, version 1.1*

This app seams to be the only one on the Apple App Store that lets you use your own API key.

**Developer response:** Thank you very much for your high praise. We will strive to do even better. 💪
