TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site owners and editors who upload images to the media library and want alt text filled in without doing it manually. It solves the problem of missing image alt text by automatically generating it using AI services or by copying existing titles, both on upload and in bulk for existing images.

OpenAI API generation (GPT-4o, GPT-4o Mini, o1 Mini)
Anthropic Claude API generation
Azure Computer Vision generation
Azure Translator multi-language support
Copies article title as alt text
Copies image title as alt text
Bulk alt text generation in Media Library
WP-CLI batch generation

Frequently Asked Questions

Common questions about Auto Alt Text

No. If you want to leverage the capabilities of AI you need an account with one of the supported services (OpenAI, Anthropic Claude, Google Gemini or Azure) and its API Key. Otherwise you can choose one of the two methods that do not use AI, which copy the title of the article or the title of the image.

Any of the AI based methods ("OpenAI's APIs", "Anthropic's APIs", "Google Gemini's APIs" or "Azure's APIs") produces a real description of the image content. The methods based on the article title or on the attachment title do not look at the image at all, so they should be seen as a quick fallback rather than as an accessible description.

The plugin is free, but the AI services are not: every generated alt text is a request billed by the provider you chose, according to its own pricing. Costs and usage statistics are always available in your provider account.

Yes, in three ways: the "Generate alt text" bulk action in the list view of the Media Library, the "Generate alt text" button available on each image in the grid view, and the WP-CLI command wp auto-alt-text generate, which is the recommended option for large libraries.

Use WP-CLI. Every alt text is generated with a call to an external AI service, so the time needed for the bulk action in the Media Library grows with the number of selected images: depending on your server settings (PHP max_execution_time, PHP-FPM request_terminate_timeout, the web server or the proxy timeout) the request can be interrupted before all the images have been processed, and the images that were not reached yet are left without alt text. WP-CLI runs from the command line, where those web timeouts do not apply, it shows a progress bar, and it can be resumed at any time. As a rule of thumb, use the Media Library for a handful of images and WP-CLI from a few dozen upwards.

Run the command from the root of your WordPress installation. For a specific list of attachment IDs: wp auto-alt-text generate --ids=123,456,789 For the whole media library, in batches: wp auto-alt-text generate --all --limit=200 --offset=0 wp auto-alt-text generate --all --limit=200 --offset=200 Only images are processed; other attachments are skipped.

--ids= a comma-separated list of attachment IDs; --all to process the image attachments of the whole library; --limit=<n> the maximum number of attachments to process (it defaults to 100 with --all); --offset=<n> where to start from when using --all; --dry-run to see what would happen without saving anything (the alt text is still generated, and therefore still billed by the AI provider); --force to regenerate the alt text even when the "Keep existing alt text" option is enabled. Either --ids or --all is required. At the end of the run the command prints how many images were processed, updated, skipped and failed.

Yes. It generates the alt text with the same method, provider, model and prompt you configured in the plugin options, it honours the "Keep existing alt text" option (unless you pass --force) and it writes the failed calls to the Auto Alt Text » Error log page, exactly like the Media Library. Remember that each generated alt text is a request billed by your AI provider, so it is a good idea to try a small batch first (for example with --limit=10) before processing thousands of images.

No, if the "Keep existing alt text" option is enabled: images that already have an alt text are skipped. The single image button in the media library always regenerates the alt text of the image you clicked, and with WP-CLI you can force the regeneration with the --force flag.

The most common reason is the file format: each service supports a specific set of MIME types (for example Google Gemini does not support GIF images), and images that are not supported by the selected provider are skipped. It may also be that the API call failed: in that case the image is uploaded anyway, without alt text, and the reason is recorded on the Auto Alt Text » Error log page.
