Important: This plugin comes with a Free Trial: You will get some free credits to test the plugin out. However, to use it further, you will need to purchase a credits package.
No setup required – Imagerr AI uses its own built-in ChatGPT API access. You don’t need your own API key.
Besides the image Alt text, this plugin can generate the following too: 
– Image Title 
– Image Caption 
– Image Description
The Imagerr AI plugin has been developed to work specifically with WordPress. It works with any WordPress theme or page builder. You can also use it apart from WordPress, through its web app.
Using this plugin, an ALT text will be generated for your WordPress media library image(s) with just one click or automatically when the images are uploaded. You can also generate the ALT texts in bulk for all your images.
New: With the “Replace on posts” option during Bulk Generation, the plugin will now search for each image across all post types (including Elementor and Divi content) and automatically update its alt text everywhere it’s used — not just in the media library. This ensures that reused images always show the most accurate and updated alt text across your entire website. 
This is a unique feature that sets Imagerr AI apart from other similar plugins.
The plugin uses the modern Chat GPT integration (no setup needed), which generates high-quality, accurate alt texts for all your photos and images.
Besides SEO, nice descriptive image ALT texts are essential for a good accessibility score of your WordPress website or blog. With this plugin, you can take advantage of this.
