## Description

Pow Captcha is a WordPress plugin that adds Proof of Work (PoW) captcha verification
to your forms. This provides an effective way to prevent spam and bot submissions
without requiring users to solve visual puzzles or complete complex challenges.

The plugin integrates seamlessly with popular form plugins including:

 * Contact Form 7
 * Gravity Forms
 * And more coming soon

Features:

 * Lightweight and fast
 * No visual puzzles for users
 * Effective spam protection
 * Easy integration with existing forms
 * Customizable difficulty levels
 * Developer-friendly with hooks and filters

### WP-CLI commands

your-captcha-service.com” wp pow-captcha set_enable_on_login_form true

wp pow-captcha status

## Installation

 1. Upload the plugin files to the `/wp-content/plugins/pow-captcha` directory, or

## FAQ

### 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.
