Is my messaging clear? Hey guys, some time ago I created a service and a lot of people told me on reddit, that my messaging wasn't clear enough. I took a pause and after a while redid the main page, I am no marketer, si I have no idea what works, what not. Can you please try to rate my landing? is it clear what is it, or did it take a lot of effort to understand? thanks for your time guys, I appreciate it. https://namiru.ai is the service submitted by /u/Appropriate-Career6

Free security + AI visibility scan. No signup needed. Just finished a project called [Shipleak]( https://www.shipleak.com ). You paste a URL, it runs 65 checks against the live site, takes about twenty seconds.
