I have only started to use Katteb recently, so here is what I thought after trying some of the features.

Fact checked AI writer works great in both English and Japanese.

Long form article is good. It takes about a minute to produce a decent article. There are some odd translations but it’s not too bad.

I LOVE the Credible Writer. Because I can add source URL, it pulls useful information from the website which means there is no odd translation.

AI art generator is OK. It’s still in beta, so I don’t expect it to be perfect. Sometimes it takes too long like over 5 minutes and I am not patient enough to wait for it. I like some images it produced.

Song Lyrics is surprisingly good in English. It doesn’t rhyme in Japanese.

I think it’s an amazing value for the price. I’ve got 2 other AI writer ( WordHero and AISEO.ai ) and Katteb is a great addition. I highly recommend it.
