I have purchased many AI tools.
As far as I am concerned, all AI tools are essentially the same, since most of them use GPT3.

I think most people choose which tool to use based on whether the tool can be used unlimitedly, whether it can write long sentences, and whether it supports their own language.
Fortunately, Japanese is supported, so I decided to purchase it.

I found creator.AI to be a tool with a high level of translation and paraphrasing capabilities.
I pay Deepl monthly and the translation function seems to be pretty close in performance.
This alone is a good reason to buy it.The ability to translate up to 10000 characters at once is also excellent.

Don't miss out on APPSUMO's unlimited plan, even though it costs more because it uses the highest quality GPT-3Davinci.

Wish for additional features
I would like to see AI available for GPT-J and others.
The reason is that GPT3 is restricted from using foul, sexual, or violent language, so only clean sentences can be created. It would be more useful for more sentence creation if we can choose GPT-J models without restrictions depending on the genre of sentences.

Also, regarding translation, I would like to be able to do this through the API if possible.
Then there would be no reason to use Deepl altogether.
