I was convinced by the idea. The setup of the API key could be explained a little better. But with other instructions, I was able to set up the key and a starting credit within 15 minutes.

I have generated various texts in German. The results were unsatisfactory. The formatting (import Markdown in Wordpress) did not fit. Umlauts and special characters were all displayed incorrectly. The form of address (I, you, you) did not fit - yes, I know, the German language has its peculiarities.
The content of the texts was too superficial for me. I missed the fine-tuning and the precision of the texts. I only have the option of creating a profile and then entering a keyword, from which a larger text is then created.
The generated texts are not usable for me in German. I had to edit the texts manually.
In view of the low price, I considered keeping it for a long time. But I still wouldn't use it because I use my own prompts directly in ChatGPT for text creation.

The idea is good, the price is very good. The implementation may be sufficient for many users. I would like to rate it fairly and give it 3 tacos (even if it would only be one taco for me personally).
