Documentation

Everything you need to install and use AI Alt Text — from your first setting to bulk generation. No API key to create, on either plan.

1. Installation

  1. From your WordPress dashboard, go to Plugins > Add New.
  2. Search for "AI Alt Text".
  3. Click Install, then Activate.

A new Settings > AI Alt Text menu appears in your dashboard. It's already working at this point — no API key or AI provider account to create.

2. Plugin configuration

Nothing is required to get started. Two optional settings if you want to customize things:

  1. Go to Settings > AI Alt Text
  2. Choose the desired generation language from the dropdown list
  3. Make sure "Automatically generate..." is checked (enabled by default)
  4. Click Save
The generation language isn't auto-detected from your content — you set it yourself. If your text comes back in the wrong language, check this field first.

3. How it works

Automatic generation: every time you upload a new image to your media library, AI Alt Text generates alt text if the image doesn't already have any. An image that already has alt text is never modified.

Media library scan: the "Scan my media library" button (in settings) scans all your existing images and shows how many are missing alt text.

Bulk generation: automatically processes every image found by the scan, instead of fixing them one by one — included in both the free and Pro plans.

4. Free vs Pro

The free quota resets automatically on the 1st of every month.

5. Troubleshooting

SymptomLikely cause
Alt text stays empty after uploadMonthly quota reached (check the notice in your WordPress dashboard), or "Automatic generation" unchecked
Text comes back in the wrong languageFix the "Generation language" field in settings
Nothing happens on an existing imageExpected: automatic generation only applies to new uploads. Use "Scan my media library" to process existing images in bulk
If the free monthly quota is reached, a notice appears directly in your WordPress dashboard — your generations reset the following month, or you can upgrade to Pro right away.

6. Upgrade to Pro

From Settings > AI Alt Text, click "Upgrade to Pro — unlimited generations". Payment and license management are handled securely by Freemius; still no API key to configure.
