WMM AI Alt-Text is built for WordPress agencies and freelance developers managing multiple client sites. Generate accessible image alt text automatically using OpenAI or Anthropic — with your own API key, so you control costs and bill clients transparently.
Every feature is free and fully functional. There are no usage caps, no locked features, and no paid tier inside this plugin — your only cost is what your AI provider charges for the API calls you make.
<h4>What’s included</h4>
<ul>
<li>Bring Your Own Key (BYOK) — use your own OpenAI or Anthropic key; no per-image markup, no usage caps from us, no surprise invoices</li>
<li>Auto-generate on upload — new images get accessible alt text automatically</li>
<li>One-click generation — a “Generate alt (AI)” button on any existing image in the Media Library</li>
<li>Bulk regenerate — process an entire media library in one background run, with pause/resume/cancel and a USD cost cap</li>
<li>Multi-language — generate alt text in 30+ languages</li>
<li>Custom prompt templates — tune output for e-commerce SEO, editorial register, or technical detail</li>
<li>Cost estimator — see estimated $ before any batch run, no surprises</li>
<li>History / audit log — every generation logged with provider, model, language, and estimated cost</li>
<li>Settings export / import — configure one site, replicate the configuration across every client</li>
<li>Health-check tool — one-click diagnostic JSON for support escalations</li>
</ul>
<h4>Why agencies prefer BYOK</h4>
When you manage 20+ client sites, opaque per-image pricing destroys your margins or forces you into ugly markups. BYOK lets you:
<ul>
<li>Use the OpenAI / Anthropic key the client already pays for — pure pass-through, no markup games</li>
<li>Or use your own agency key and bill the small API cost as a clear line item</li>
<li>Avoid being held hostage to a SaaS vendor’s price hikes</li>
</ul>
<h4>Cost transparency</h4>
At current <code>gpt-4o-mini</code> pricing (~$0.00015 per image), processing 10,000 images costs about $1.50. The plugin shows estimated cost before any batch run, and logs actual cost after.

<h3>External services</h3>
This plugin sends your images to the third-party AI provider you choose and configure (OpenAI or Anthropic) in order to generate alt text. It uses your own API key; no data passes through Webmaster & More servers. You must have an account with the provider you select.
OpenAI (used when “OpenAI” is the selected provider) 
What it is and what it’s used for: OpenAI’s vision API generates the alt-text description for an image. This cannot be done locally — it requires the provider’s model. 
What data is sent and when: the image (as a public URL, or the image bytes if the site is not publicly reachable) together with a short text prompt is sent to <code>https://api.openai.com</code> each time alt text is generated — on upload (if auto-generate is on), when you click the per-image button, and for each image during a bulk run. A lightweight models-list request is also sent to verify your key when you click “Test key”.

Anthropic (used when “Anthropic” is the selected provider) 
What it is and what it’s used for: Anthropic’s Claude vision API generates the alt-text description for an image. This cannot be done locally — it requires the provider’s model. 
What data is sent and when: the image (as a public URL, or the image bytes if the site is not publicly reachable) together with a short text prompt is sent to <code>https://api.anthropic.com</code> each time alt text is generated — on upload (if auto-generate is on), when you click the per-image button, and for each image during a bulk run.
