TL;DR

AI summary of the plugin's readme

Really Simple CAPTCHA is for plugin developers who want to add CAPTCHA functionality to their own WordPress plugins, originally built for Contact Form 7. It provides basic CAPTCHA generation and verification using temporary image and text files instead of PHP sessions, avoiding session-related conflicts within WordPress.
