🚀 WordPress AI Excerpt Generator (Gemini Powered)

Automatically generate SEO-friendly blog excerpts for WordPress posts using Google Gemini AI in a single click.

This plugin scans your website for posts that do not have excerpts, reads the article content, and generates short compelling summaries designed to improve click-through rate, SEO snippets, and content presentation.

What normally takes hours of manual writing can now be completed in seconds.

✨ Features

⚡ One-Click AI Excerpt Generation

Generate excerpts for hundreds or thousands of blog posts instantly.

The plugin automatically:

  1. Scans all posts
  2. Detects posts missing excerpts
  3. Sends content to Google Gemini AI
  4. Generates engaging summaries
  5. Updates the WordPress excerpt field

🤖 Powered by Google Gemini AI

Uses the fast and efficient model:

Gemini 2.5 Flash Lite

Prompt used:

Write a 22–28 word blog excerpt encouraging readers to click the article. Do not repeat the title.

This produces high-quality click-driving summaries perfect for:

  • Blog archive pages
  • Search result snippets
  • Homepage previews
  • Content feeds

📊 Live Progress Tracking

The plugin includes a real-time dashboard with:

  • Progress bar
  • Number of posts processed
  • Live generation logs
  • Generated titles
  • Error tracking

🧠 Smart Batch Processing

To prevent server overload, the plugin processes posts in batches of 10.

Benefits:

✔ Prevents server crashes
✔ Avoids API throttling
✔ Works smoothly with large websites
✔ Efficient processing for thousands of posts

🔐 Built-in Daily API Limit

The plugin includes a daily usage control system.

Example configuration inside the plugin:

WAEG_DAILY_LIMIT = 300

Once the limit is reached, generation automatically stops until the next day.

This prevents accidental API overuse.

📈 SEO Benefits

Adding excerpts improves:

✔ Blog feed quality
✔ Search engine previews
✔ Click-through rate
