== Frequently Asked Questions ==

= How does Pow Captcha work? =

Pow Captcha uses a Proof of Work algorithm that requires browsers to perform a computational task before submitting forms. This is transparent to users but effectively blocks automated bot submissions.

Currently, the plugin supports Contact Form 7 and Gravity Forms. More integrations are planned for future releases.
