Automatic duplicate/copy of post to a related page in WordPress

I have a website about introducing softwares and apps. I created pages and so menus (named by categories).

I set my WordPress setting homepage to latest posts. I create posts and give them categories and tags.

I like to have the option to automatically create a copy of content of a post in related page, in which this relation might be its category?

Is there such possibility inside WP or some free plugins?

Thanks.
