The tool got sooo good!
I purchased the first code like a year ago to get some help with blog post writing and the tool was good, but I wasn't super amazed by it - now I came back and instantly bought a lot more codes because the tool got so much better over time!
Especially the "tone of voice" option is valuable for me, so I can speak to different people in different ways about the same topic. This combined with the SEO writing makes the daily work so much easier.
Besides blogs, it also offers so many good templates (Facebook or LinkedIn posts, video scripts, email copy, etc.) - as a digital product creator, you get everything you need in one tool when it comes to text work.
To me, Katteb is a time saver with really good quality output (I'm still not copying and pasting all of it and make some human changes, but the base you get from the tool is great).
If I could wish for another feature to be included, it would be Etsy Product descriptions :-)
