Gave it a quick try and it seems like a useful tool. I'm not 100% sure how accurate it is yet, will get a paid account to test more. An article I put in as a test that was written by AI but manipulated a few times and passed other AI detectors scored 99% AI in this app. Pretty huge difference! They way they quote pricing is misleading. They say 1 credit for 100 words BUT that is for AI detection OR plagiarism/readability. If you have both turned on, it is double that. Still a fairly reasonable price but not thrilled with how they quietly slip in a 100% price increase.

InLinks is absolutely amazing for content optimization, internal linking and schema . I love how it prompts you to optimize for the entities/topics Google recognizes, not just keywords. The internal linking automation saves several hours every month especially with the RSS feed that automatically adds links to your blog as you post new content. All round brilliant tool!
