Having recently compared a few AI writers, abun was the best of the bunch. My articles were detailed, well-organized, and (most importantly) factual. Some even included tables where appropriate. 2 minor features aren't 100% perfect yet - the image generator would return the same image after a few pushes of the "Generate New" button, and there were fewer internal links than expected (probably because I need more content on the site).

The keyword research functionality, complete with integration into the prompts, is a huge time-saver. A few other tools were returned, but this one is a keeper!
