Can I give my posts a word limit (not full content) with the Better Excerpts extension?

WPeMatico Better Excerpts only saves excerpts; it doesn’t touch the post contents.  If you will only be using excerpts on your website, it can do the job.

But if you want to use the post content with images, links or other html tags inside, you’ll need the WPeMatico Professional add-on

Feature: Word count filters

Strips the HTML and counts how many words or letters are in the content, and allows you to assign a category, cut the content or skip the post.
