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.

Is it compatible with my form plugin?

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