[Plugin: WP Captcha-Free] using captcha free with any form or outside wordpress?

im very impressed with this plugin, and dont understand why we dont see it used more across the web. is there any way to use this plugin with random form fields in wordpress? or is there a way to reuse this anywhere with a php/js script? id like to just make a really simple form based page on my site and want to use captcha free, but not really sure how to do it

thanks for the plugin and any info, keep up the great work!
david
