Do you sometimes wonder why we enjoy watching AI content? Is it because they are simply visually aesthetic to watch? Or is it because they are creative? 

No! Most of us enjoy them because they are imperfect, which makes them hilarious, and we love to make fun of them.

However, when it comes to running a marketing campaign with AI-generated content, the imperfections or comic elements do not work.

In 2024, Coca-Cola launched an AI-generated Christmas ad featuring the slogan " The holidays are coming". Most of the viewers have heavily criticised the ad, calling it “distasteful” and “soulless”. 

People are emotionally attached to both Christmas and Coca-Cola. So, they expect the Christmas ad campaign from them to be perfect.  

Whenever you make content with AI, you have to make sure that the content looks flawless enough to convince the audience. And to do that, the very first and fundamental step is to detect AI in the content. 

So, here are the seven best AI checkers for content in 2026.
