Getting Free Online Tool Site Approved

Heu guys,

I'm running a free online tool site that generates title ideas for content creators. The URL is http://writinghelp911.com/.

As you can understand, it's supposed to provide the value to the visitors only after they enter the keyword or topic. This is the idea of the project.

I've even added a few text blocks to make google a bit happier with my site, but it's still getting dissaproved.

The question is: do one-page free online tool sites get approved for Google Adsense nowadays?
I've seen some similar sites with google adsense on them (example: https://tarkovserverstatus.com/) , but maybe they got approved a couple of years ago.

I'd also appreciate any recommendations / thoughts on how to make this happen.

Thanks in advance!
