TDF Image Alt Scanner scans your entire WordPress site for images with missing or low-quality alt text and gives you a single place to fix them — across posts, pages, custom post types, the Media Library, and WooCommerce products.
Missing alt text is one of the most common and most expensive mistakes on the web:
<ul>
<li>SEO — Google uses alt text to understand image content. Missing alts hurt image search rankings and reduce the contextual relevance of your pages.</li>
<li>Accessibility — Screen readers depend on alt text. Missing alts exclude users with visual impairments from understanding your content.</li>
<li>Compliance — WCAG 2.1 / 2.2 and the European Accessibility Act both require alt text on meaningful images. UK and EU sites that ignore this face increasing legal exposure.</li>
</ul>
TDF Image Alt Scanner finds the gaps in minutes and gives you the tools to fix them.
<h4>How it works</h4>
<ol>
<li>Click Run scan. The plugin walks your posts, pages, custom post types, Media Library, and WooCommerce galleries.</li>
<li>Each image is classified as Missing, Decorative, Filename (alt text equals the file name — useless to screen readers), or Valid.</li>
<li>The Results table shows everything in one place. Edit alt text inline; mark genuinely decorative images so they’re skipped by screen readers; export everything to CSV for review.</li>
<li>Re-run the scan whenever you want to see your compliance score improve.</li>
</ol>
<h4>Free version features</h4>
<ul>
<li>Full site scan — every image on your site.</li>
<li>Compliance score dashboard with scan history.</li>
<li>Sortable, filterable bulk-edit table — filter by status, post type, or sort by date.</li>
<li>Inline edit and save per image, with “mark as decorative” toggle.</li>
<li>Detection of missing alt, decorative alt, and “alt equals filename” cases.</li>
<li>CSV export of every audit row.</li>
<li>Scans posts, pages, custom post types, Media Library, and WooCommerce products (including variations and gallery images).</li>
<li>Gutenberg-aware: handles core/image, core/cover, core/gallery, and nested blocks.</li>
</ul>
<h4>Pro features (sold separately)</h4>

</ul>
<h4>Privacy</h4>
TDF Image Alt Scanner does not send any data off your site. The plugin only uses the WordPress REST API to communicate between the dashboard and your site’s database.
If you upgrade to Pro and enable AI alt text generation, you will be entering your own API key for one of the supported AI providers. In that case, image URLs and prompts are sent directly from your site to the AI provider you’ve chosen — TDF Image Alt Scanner never sees or stores them.
<h4>Source code & building from source</h4>
The admin dashboard is a React app compiled with Vite. The unminified source is shipped inside the plugin zip at <code>admin/react/src/</code> and can be rebuilt with:
<pre><code>cd admin/react && npm install && npm run build
</code></pre>
That regenerates the bundle at <code>admin/dist/</code>. Source files: <code>admin/react/src/*.jsx</code>, <code>admin/react/src/*.js</code>, <code>admin/react/src/styles.css</code>. Build config: <code>admin/react/package.json</code>, <code>admin/react/vite.config.js</code>.

A11yBridge adds a visitor-friendly accessibility toolbar to your WordPress site. Visitors can adjust the visual appearance and navigation of your content with one click.
Video demo: 
https://www.youtube.com/watch?v=DEINE_VIDEO_ID
Core features (no external backend, works offline): 
* Font size controls 
* Contrast adjustments 
* Focus mode (reduce distractions / highlight content area) 
* Color-blindness filters / color adjustments 
* Keyboard navigation support 
* Text-to-speech (TTS)
Optional AI feature: 
* AI-powered text simplification (multiple levels and languages)
Important note: 
This plugin can improve usability and accessibility, but it cannot guarantee full compliance with WCAG or any specific legal requirement. Always test your site with real assistive technologies and accessibility audits.
<h3>AI features (optional)</h3>
AI text simplification is processed on A11yBridge servers in Germany. Backend features are disabled by default and are only used after the site owner enables them (or activates a license). Any usage limits are enforced by the external service and depend on the service subscription associated with the installation. 
All non-AI accessibility tools (toolbar, contrast, focus mode, keyboard support, text-to-speech) work without any AI connection.
The plugin itself does not lock or restrict built-in/local functionality based on a license key, trial period, or local usage counters. 
If the service quota is exceeded, the service returns an error response and the plugin displays a notice.
<h3>External Services / Data Transmission</h3>
This plugin can optionally connect to A11yBridge backend services to provide AI text simplification and related service operations (e.g., quota management, license activation, abuse prevention). For WP.org compliance, it does NOT contact external servers by default. External requests happen only after explicit admin opt-in (backend enabled / AI feature enabled) or after the admin activates a license key.
Service endpoint(s):
<ul>
<li>https://a11ybridge.de/wp-json/a11ybridge/v1
<ul>
<li>/license/status (read current license/installation status)</li>
<li>/license/activate (activate/bind license to this site)</li>
<li>/license/domains/delete (remove domain binding from license)</li>
<li>/free/status (free-tier quota status, only after admin opt-in)</li>
<li>/chat/simplify (AI text simplification, only when triggered by the user)</li>
</ul>
</li>
</ul>
What data may be transmitted (depending on enabled features):
Local storage / Cookies on the site where the plugin is installed:
To remember accessibility preferences for visitors, A11yBridge stores settings in the visitor’s browser storage and (for guests) may also store a pseudonymous guest identifier.
Browser storage (localStorage) keys used by the frontend may include: 
* a11ybridge_plugin_settings (visitor accessibility preferences) 
* A11YBRIDGE_USER_LOCAL_V1 (visitor feature flags/preferences) 
* a11ybridge_colorMode (display mode) 
* a11ybridge:consent:text_simplify: (stores the visitor’s consent decision for AI text simplification prompts)
Cookie (functional): 
* a11ybridge_guest_id (random pseudonymous ID for guest settings; used to associate guest preferences stored on the same WordPress installation; expires after 30 days; SameSite=Lax; Secure on HTTPS)
This storage is used only to provide the requested accessibility features and is not used for advertising or cross-site tracking. Site owners should document this storage in their privacy/cookie documentation as required by applicable law.
<ul>
<li>Selected text submitted by the user for AI text simplification (only when the user triggers simplification)</li>
<li>Pseudonymous installation ID</li>
<li>Domain/host (only after admin opt-in or license activation)</li>

</ul>
Purposes:
