Free one. I found it to be a lot worse than Chat GPT’s free tier. I didn’t test it mega in depth but I threw some of the same “rewrite this copy but make it better in <this> way” sort of tasks I’ve used GPT for and it turned around ridiculously bad writing.
I then asked it if it thought that what it had produced was good writing and comically it told me that it was bad and full of cliches and that I should avoid using it. I’m not making that up.
