To deliver accessibility scanning, agentic AI remediation, and the accessibility widget, the plugin communicates with AllAccessible’s servers. This section discloses what data is sent and where, per WordPress.org guidelines. What the plugin connects to AllAccessible API (app.allaccessible.org) — validates your license, retrieves widget settings, serves accessibility audit scores, and accepts manual edits (alt text, fix approvals). Requests are authenticated and only made when you use the plugin’s admin screens or when the widget loads on your site. Data sent License & account identification — your AllAccessible account ID and site URL, so the service knows which account a request belongs to. Accessibility audit data — when the widget scans a page, detected accessibility issues are sent so the service can compute scores and generate remediation suggestions. Error & diagnostic information — if the plugin encounters an error, anonymized diagnostic details (error message, plugin version, WordPress/PHP version, your account ID) are sent to our error-monitoring service (Sentry) so we can detect and fix problems. This is disclosed in our Privacy Policy and can be disabled under Account → Advanced → “Disable error reporting to AllAccessible.” No data is sent without an account The free accessibility widget runs entirely in the visitor’s browser and adjusts their viewing experience only. License-bound features (AI remediation, scanning, image descriptions) require an AllAccessible account; creating one means agreeing to our Terms and Privacy Policy, which govern all data handling.

This plugin implements the automatic creation of alt text for images uploaded to the media library. The alt text is generated at the time of uploading the image and it is also possible to generate the alt text for images already present in the media library. To generate the alt text, you can choose to use the artificial intelligence of OpenAI or Azure, or decide if you simply want to copy the title of the article where the image is uploaded or the name of the image. Clearly, using artificial intelligence will allow for a more accurate and useful alt texts. Features This plugin allows you to generate alt texts in the following ways: – using Openai APIs (GPT-4o, GPT-4o Mini, o1 Mini) – using Anthropic Claude API – using Azure APIs for computational vision; – recovering the title of the image – recovering the title of the article in which the image is uploaded Getting Started After installing the plugin, click on the ‘Auto Alt Text’ menu item. Choice of Generation Method Select the Generation Method you prefer OpenAI’s APIs In your OpenAI account, retrieve the following data to enter on the options page: – API Key Choose the model you want to use for generating the alt text. Enter a prompt for generating the alt text according to your needs. Claude Anthropic’s APIs In your Anthropic account, retrieve the following data to enter on the options page: – API Key Choose the model you want to use for generating the alt text. Enter a prompt for generating the alt text according to your needs. Azure’s APIs On your Azure account, create a Computer Vision instance and retrieve the following data to enter on the options page: – Computer Vision API Key – Computer Vision Endpoint If you want to generate an alt text in English, save the options without filling in any other fields. If you want to generate an alt text in a different language, on your Azure account, create a Translator instance and retrieve the following data to enter on the options page: – Translator Instance API Key – Translator Instance Endpoint – Translator Instance Region After entering this data, save the options. Select the desired language and save the options again. Title of the article For this generation method, there are no options to set as the alt text will be generated by copying the title of the article in which the image is uploaded. In case the article is not uploaded as an attachment of an article, the “Title of the attachment” method will be used as a fallback. Title of the attachment For this generation method, there are no options to set as the alt text will be generated by copying the title of the image. Functioning Once the plugin is configured, each time an image is uploaded to the media library, an alt text will be automatically set based on the selected generation method. For images already in the media library, you can create bulk alt texts. Open the Media Library in the “list” view, select the images for which to generate the alt text, and choose the “Generate alt text” bulk action. (Depending on the number of images chosen and their weight, this may take some time.) You can also generate the alt text of a single image directly from the media library. Open the Media Library in “grid” mode, choose the image for which to generate the alt text, and click the “Generate alt text” button. In no time the alt text field will be overwritten by the generated description. WP-CLI If you prefer generating alt text in batch (e.g., to avoid processing in the Media Library UI), you can use WP-CLI. Generate alt text for a list of attachment IDs: wp auto-alt-text generate --ids=123,456,789 Process all image attachments in batches: wp auto-alt-text generate --all --limit=200 --offset=0 wp auto-alt-text generate --all --limit=200 --offset=200 Dry run (no metadata updates): wp auto-alt-text generate --ids=123,456 --dry-run Force overwrite of existing alt text (even if “Keep existing alt text” is enabled): wp auto-alt-text generate --all --limit=200 --offset=0 --force Notice: If you choose one of the methods that involves the use of external APIs, the upload times for images in the media library might increase because it requires sending a request to the APIs, waiting for the external server to process, and waiting for a response. Logging If the generation of the alt text via AI is set, in case of errors, to avoid blocking the editorial work, the image is loaded anyway but without the alt text being compiled. When a call to the Azure or OpenAI API fails, a record containing the error message is saved in a custom database table. In this case, the cause of the error can be seen on the Auto Alt Text -> Error log page. External Services This plugin uses the following external services alternatively: OpenAI Selecting the generation method “OpenAI’s APIs” will use the API services of OpenAI. This plugin does not collect any information from your OpenAI account. The data transmitted to OpenAI mainly consists of the image files uploaded to your website and the specified prompt. For accurate information on privacy and conditions of use, please consult the privacy policy and terms and conditions directly on the official website. It is also advisable to check the costs and usage statistics of the API service on the OpenAI website. Anthropic Claude Selecting the generation method “Anthropic’s APIs” will use the API services of Anthropic. This plugin does not collect any information from your Anthropic Claude account. The data transmitted to Anthropic Claude mainly consists of the image files uploaded to your website and the specified prompt. For accurate information on privacy and conditions of use, please consult the privacy policy, terms and conditions for consumers and terms and conditions for commercial directly on the official website. It is also advisable to check the costs and usage statistics of the API service on the Anthropic website. Azure Selecting the “Azure’s APIs” generation method will use the API services of Microsoft Azure. This plugin does not collect any information from your Azure account. The data transmitted to Azure consists mainly of image files uploaded to your website. For accurate information on privacy and conditions of use, please directly consult the privacy policy and terms and conditions on the official website. It is also advisable to check the costs and usage statistics of the API service on the Microsoft Azure’s website. Encryption Constants We strongly recommend defining the new plugin-specific constants in your wp-config.php: define( 'AAT_ENCRYPTION_KEY', 'a_random_string_of_at_least_64_characters' ); define( 'AAT_ENCRYPTION_SALT', 'another_random_string_of_at_least_64_characters' ); You will find these two define(…) lines already generated for you on the Auto Alt Text » Options page – simply copy & paste them before the /* That's all, stop editing! Happy publishing. */ line in your wp-config.php. If you choose not to add them, the plugin will continue to work normally, but it will fall back to using your WordPress LOGGED_IN_KEY / LOGGED_IN_SALT, which may break if those salts are ever changed.
