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>

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.
