Plugin to automatically generate blog content using Google Gemini AI with random topics and system cron support.

== Description ==

AI Auto Blog is a revolutionary plugin that allows you to feed your WordPress blog autonomously using Google Gemini artificial intelligence. The plugin automatically generates complete, quality articles with customizable topics and reliable system cron execution.

= Main Features =

• Automatic Content Generation: Creates complete articles using Google Gemini AI (2.5 Flash, 2.5 Pro, 2.0 Flash)
• Random Topics System: Configure topic lists for varied content generation
• System Cron Support: Execute via system cron for 100% reliability (no WP-Cron dependence)
• Custom Post Type: Separates AI posts from your regular entries
• Complete Customization: Define style, theme and criteria for your posts
• Multiple Lengths: Choose between brief (~500 words), medium (~1000) or long (~2000) posts
• Flexible Scheduling: Manual, daily, weekly or monthly generation
• Cron Diagnostics: Built-in tools to detect and fix scheduling issues
• Detailed Statistics: Monitor all generations and their status
• Email Notifications: Receive alerts when new content is generated

= Why Use This Plugin? =

• Reliable: System cron ensures execution at exact times
• Flexible: Random topics keep your content varied
• Transparent: Detailed logs and diagnostics
• Powerful: Latest Gemini 2.x models
• Safe: No data collection, local API key storage

= Requirements =

• Google AI Studio API Key (free at https://makersuite.google.com/app/apikey)
• WordPress 5.8 or higher
• PHP 7.4 or higher
• SSH or cPanel access (for system cron setup)

== Installation ==

1. Upload the ai-auto-blog folder to the /wp-content/plugins/ directory
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Go to 'Settings' → 'AI Auto Blog'
4. Enter your Google Gemini API Key
5. Configure your generation preferences
6. Ready! You can generate your first post

= System Cron Setup (Recommended for Reliability) =

For maximum reliability, use system cron instead of WP-Cron:

Step 1: Run test script via SSH:

cd /path/to/wp-content/plugins/ai-auto-blog
php cron-test.php

Step 2: Add to wp-config.php:

define('DISABLE_WP_CRON', true);

Step 3: Add to server cron (cPanel or crontab):

0 9 * * * /usr/bin/php /path/to/cron-generate.php >> /tmp/ai-auto-blog-cron.log 2>&1

See included documentation for detailed instructions.

== Frequently Asked Questions ==

= Is it free? =

The plugin is free. You need a Google Gemini API key which has a generous free quota.

= Can I customize the generated content? =

Yes, the "System Prompt" field allows you to define style, tone and themes. You can also configure random topics for variety.

= How good is the generated content? =

Content is generated by Google Gemini 2.x, one of the most advanced AI models. Quality depends on your prompt configuration.

= Why use system cron instead of WP-Cron? =

System cron is more reliable because:

• Does not depend on site visits
• Executes at exact scheduled times
• Prevents accumulated/blocked events
• Better for all traffic levels

= Can I use this for sites in other languages? =

Yes, configure your prompt in the desired language and Gemini will generate content in that language.

= What if automatic generation stops working? =

Use the built-in Cron Diagnostics tab (Settings → AI Auto Blog → Diagnostics) to identify and fix the problem.
