AI Alt Text Generator vs Alt Magic

AI Alt Text Generator writes clear, descriptive alt text for every image on your WordPress site — improving accessibility compliance (WCAG 2.2, ADA, Section 508, and the European Accessibility Act) and image SEO at the same time. It works out of the box: activate the plugin and start generating, no API key and no signup required. Every site gets 50 free images per month through the built-in managed credits service. That makes it a fit for small organizations that need accessible, legally compliant websites but don’t want to wrangle developer accounts or AI billing — nonprofits, churches, schools, clinics, and small businesses working toward WCAG / EU Accessibility Act compliance. Alt text is required for accessible, legally compliant websites, and it helps search engines understand your images. But writing it by hand across an entire media library rarely happens — so this plugin does it for you, in bulk or automatically on upload. It produces concise, WCAG-aligned descriptions (no “image of…” filler, sensible length) and can fold in the page context and your SEO focus keyphrase for sharper, more relevant alt text. It pairs perfectly with accessibility audit tools that flag missing alt text — this is the plugin that fills the gaps. How it works — two ways to generate: Managed credits (default, recommended) — No API key, no signup. The plugin connects to the AI Alt Text Generator managed service automatically and gives every site 50 free images per month. Need more? Affordable paid credit plans are available. This uses an external, account-based service (see the disclosure below) and is optional beyond the free tier. Bring your own API key (advanced) — Prefer to run on your own OpenAI or Anthropic account? Add your own API key in the Advanced settings and generation runs at-cost, directly with your provider, with no per-image fees or vendor lock-in. You choose the provider and model.

The optional Pro add-on builds on this free plugin with: – WooCommerce product context for commerce-aware, SEO-rich alt text – Scheduled background scans that describe new and existing images automatically – A coverage analytics dashboard to track your progress toward 100% – Automatic updates and priority support Learn more about Pro — the free plugin remains fully functional on its own. External Service Usage Disclosure This plugin relies on external AI services to generate alt text. In all cases, data (images and their metadata) is sent to an external service for processing. The plugin does not store your images or generated alt text on our servers beyond what is needed to return your result. Managed credits service (default) By default the plugin uses the AI Alt Text Generator managed credits service so it works with no API key. On activation, the plugin automatically connects your site to obtain a free account (50 images per month) — this registers your site with the external service and requires an account. Images to be described are sent to this service for processing. Use beyond the free monthly tier requires a paid credit plan. The service is operated via https://store.lessbutmore.ai?utm_source=plugin&utm_medium=readme&utm_campaign=disclosure — please review the site for its terms and privacy policy. You can disable managed credits in the plugin settings and use your own API key instead. Bring-your-own-key providers (optional, advanced) If you add your own API key, images are sent to the provider you select: – OpenAI: For more information, please review the OpenAI Terms of Use and Privacy Policy – Anthropic: For more information, please review the Anthropic Terms of Service and Privacy Policy You choose which path to use and are only required to agree to the terms of the service you actually use.
