Bring your own Google Gemini or OpenAI API key; everything else is included, with no upsells. #### What it does * **Generate on upload** – new images get ALT text (and optionally a title and caption) during the upload, so it is already there when you insert the image in the editor. * **Media SEO Table** – a dedicated screen listing every image with its ALT text, title and caption. Edit inline, filter by _Missing ALT_ / _Optimized_ / _WooCommerce_, search the whole library, and paginate through thousands of images. * **Bulk Vision Scanner** – process the entire library from one screen with a live progress bar, counters and a log. Stops cleanly, retries when the provider rate- limits you, and skips images that already have manual ALT text (or rewrites everything, if you ask it to). * **Media Library integration** – an _AI Alt Text_ column with a Generate button in the list view, and a _Generate ALT text with AI_ button inside the media modal and the attachment edit screen. * **Nightly background scan** – WP-Cron quietly fixes images that are still missing ALT text, in small batches that respect shared-hosting time limits. * **WebP copies** – creates a lighter `.webp` version of the original and every thumbnail size (originals are never modified) and can optionally serve them to browsers that support WebP. Copies are removed when you delete the image. * **WooCommerce context** – product images are described with the product title, categories and SKU in mind (featured image and gallery images are both detected). Add store or brand keywords and the AI uses them only where they fit. * **Your rules** – choose what the AI looks at (the image and its filename, the image only, or the filename only without ever sending the image), the ALT style( concise SEO, descriptive accessibility or keyword focused), the output language( 30+ languages) and whether existing ALT text may be overwritten. * **Works with the WordPress AI Client** – on WordPress 7.0+ the plugin can use the provider and API key your site already has under _Settings Connectors_ ( Google, OpenAI, Anthropic or any provider plugin), so you configure AI once for every plugin and this plugin stores no credentials at all. * **Or bring your own key** – direct Google Gemini (3.7 / 3.6 / 3.5 Flash, Flash- Lite, 2.5) and OpenAI (GPT-5.6 Sol / Terra / Luna and older models) integrations for sites on WordPress 6.2–6.9 or for a dedicated key, with a custom model field so you are never stuck when a provider retires a model, plus a _Test connection_ button that sends a real test image. * **Developer friendly** – filters for the prompt, the result, the context, the model and the image size; an action after every generation. #### Privacy Only a downscaled copy of the image (max 1024 px) and a little context (the related product/post title, product categories and SKU, your brand keywords, the filename) is sent to the AI provider you choose. In “Filename only” mode the image itself is never sent. No user data, no site URL and no other content leaves your site. Nothing is sent until you add an API key. The plugin does not phone home to Cubixsol and contains no tracking. ### External services This plugin sends images to an AI service to describe them. It only does so once a provider has been set up and only when ALT text is generated (on upload, from the Generate buttons, from the bulk scanner or from the nightly cron). There are three ways to set up a provider: **WordPress AI Client** (WordPress 7.0+) – when this option is selected, the request is handed to the WordPress core AI Client, which routes it to whichever AI provider the site owner has configured under _Settings Connectors_ (for example the official AI Provider for Google / OpenAI / Anthropic plugins). This plugin does not store or transmit credentials in this mode; the terms and privacy policy of the provider configured there apply. **Google Gemini API** (Google LLC) – used when “Google Gemini” is the selected provider. The plugin sends a resized copy of the image (omitted in “Filename only” mode), the generation prompt (including the related post/product title, categories, SKU, brand keywords and filename hint) and your API key to `https://generativelanguage. googleapis.com/`. [Terms of service](https://ai.google.dev/gemini-api/terms) · [Privacy policy](https://policies.google.com/privacy) **OpenAI API** (OpenAI, L.L.C.) – used when “OpenAI” is the selected provider. The plugin sends the same data to `https://api.openai.com/`. Requests are made with ` store: false`, so OpenAI does not retain them for its stored-responses feature. [Terms of use](https://openai.com/policies/terms-of-use) · [Privacy policy](https://openai.com/policies/privacy-policy) You are responsible for the usage costs and for complying with the provider’s terms. ## Screenshots [⌊Settings – choose the WordPress AI Client or a direct Google Gemini / OpenAI key, pick a model and test the connection with a built-in image.⌉⌊Settings – choose the WordPress AI Client or a direct Google Gemini / OpenAI key, pick a model and test the connection with a built-in image.⌉[ Settings – choose the WordPress AI Client or a direct Google Gemini / OpenAI key, pick a model and test the connection with a built-in image.

[[ ## Installation 1. Upload the `altcraft-ai-image-seo` folder to `/wp-content/plugins/`, or install the plugin through the WordPress Plugins screen. 2. Activate the plugin. 3. Go to **AltCraft AI Settings & API**, choose a provider, paste your API key, click _Test connection_ and save. 4. Upload an image – or open **AltCraft AI Bulk Scanner** to fix your existing library. ## FAQ ### Should I use the WordPress AI Client or my own API key? On WordPress 7.0 or newer, the WordPress AI Client is the recommended choice: install one of the official _AI Provider_ plugins (Google, OpenAI or Anthropic), add the key once under _Settings Connectors_, and every AI-capable plugin on the site – including this one – uses it. Choose Google Gemini or OpenAI directly if your site runs an older WordPress version or you want a separate key and billing for image ALT text. ### Where do I get an API key? Google Gemini keys are created in Google AI Studio (aistudio.google.com/apikey) and include a free tier. OpenAI keys are created at platform.openai.com/api-keys and are billed per use. ### Does it overwrite ALT text I wrote myself? Not unless you tell it to. Automatic generation (upload and nightly cron) only fills empty ALT text by default. Turn on _Overwrite existing ALT_ in the settings, or choose _Every image_ in the bulk scanner, to rewrite everything. The Generate buttons always regenerate the image you clicked. ### Which image is sent to the AI? A copy no larger than 1024 px on its longest side, usually one of the thumbnail sizes WordPress already created. Your original file is never uploaded. Use the ` altcraft_ai_max_image_dimension` filter to change the size. ### Can I avoid sending my images to the AI at all? Yes. Set _What the AI looks at_ to _Filename only_. The plugin then sends just the cleaned-up filename and the related post/product title, so the AI can only describe what the name implies. Descriptive filenames (`red-leather-handbag.jpg`) work well; camera names (`IMG_4821.jpg`) on images that are not attached to anything are skipped with a clear message. ### I get “The AI provider did not respond within 60 seconds”. The image upload from your server to the provider took too long, usually because the image is large and the hosting has limited outbound bandwidth. The plugin normally sends a small thumbnail; if WordPress could not create thumbnails for that image( common with very large PNGs on low-memory hosting) the original file is sent instead. Raise the request timeout under _Settings Advanced_, regenerate thumbnails for the image, or upload a smaller copy. ### The bulk scanner says “model not found”. The provider retired the model you selected. Open the settings, pick a newer model from the list (or enter any model ID in the custom field), test the connection and save. ### I get “cURL error 28 … timed out” but the connection test works. Real generation uploads a copy of your image; normally a 768–1024 px thumbnail. When WordPress could not create thumbnails for an image (large PNGs on hosts with a low memory limit, or servers without GD/Imagick) the plugin sends the original instead, which can be several megabytes and may not upload within the timeout. Check _Settings Advanced Server capabilities_, regenerate thumbnails for the affected images (or raise the PHP memory limit), or increase _Request timeout_ under Advanced. The connection test now sends a small image through the same pipeline, so a passing test means the key, model and vision support are all fine. ### Does WebP delivery work with caching plugins and CDNs? WebP copies are always created safely. _Serving_ them swaps image URLs when the visitor’s browser sends `Accept: image/webp`, so a full-page cache must vary its cache by the Accept header (the plugin sends a `Vary: Accept` header to help). If your CDN already converts images to WebP, leave delivery off. ### Can I hard-code the API key in wp-config.php? Yes: `add_filter( 'altcraft_ai_api_key', function ( $key, $provider ) { return ' gemini' === $provider ? 'YOUR-KEY' : $key; }, 10, 2 );` ### What happens when I uninstall the plugin? Settings, transients and scheduled events are always removed. Generated ALT text, titles and captions stay in your Media Library. WebP copies and generation logs are deleted only if you enable _Clean up on uninstall_ in the Advanced tab first. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “AltCraft AI – Image SEO & Auto Alt Text Generator” is open source software.
