uhallo

Uhallo Sight is an AI alt text and image accessibility plugin for WordPress. It helps agencies, freelancers, WooCommerce teams, and site owners find missing or weak image descriptions, improve image SEO, and support WCAG image accessibility work without manually opening every media item.
Install the plugin, Connect to Uhallo, then run Start Bulk Scan from Settings -> Uhallo. Uhallo reviews your existing WordPress Media Library, detects unverified image metadata, uses OCR-first image analysis when text appears inside an image, drafts practical alt text, and writes approved fixes back into native WordPress attachment metadata. After setup, new uploads are protected too, so your site does not drift back into missing alt text.
The plugin also shows a clear WordPress admin dashboard with an Image Metadata Score, scan status, upload protection, widget coverage, trial usage, and before/after fixes. The Client Proof Summary gives agencies and consultants a simple way to show what changed: images scanned, missing or weak alt text found, verified fixes saved, new-upload protection, and recent examples.
Uhallo Sight is built for real WordPress cleanup work:
<ul>
<li>AI alt text for WordPress images and WooCommerce product media.</li>
<li>Bulk Media Library scans for old posts, pages, galleries, and uploads.</li>
<li>OCR-first descriptions for banners, menus, warning labels, charts, and screenshots with visible text.</li>
<li>Native WordPress alt text writeback, not a separate overlay-only system.</li>
<li>Optional frontend widget coverage for theme or page-builder images that need extra help.</li>
<li>Base64 firewall mode for private, staging, or locked-down WordPress sites.</li>
<li>Trial counters and proof summaries for agencies selling accessibility care plans.</li>
</ul>
<h4>External service and privacy</h4>
Uhallo Sight connects your WordPress site to the Uhallo API at https://api.uhallo.com. This external service is required for account connection, image analysis, AI alt-text generation, usage tracking, and writing generated descriptions back to WordPress.
When you connect the plugin or scan images, the plugin sends your Uhallo client identifier, signed request metadata, WordPress site URL, attachment ID, image URL or image data when firewall mode is enabled, existing alt text, filename, MIME type, and callback URL. Uhallo uses this data to generate alt text, update the matching WordPress attachment, measure usage, and keep the service secure.
The optional frontend widget is disabled by default. If a site administrator enables widget coverage, the plugin loads the Uhallo JavaScript widget from https://api.uhallo.com/uhallo.js on the public site with the connected Uhallo client identifier. The widget checks frontend images that themes or page builders render outside normal WordPress media writeback, reuses existing Uhallo-written alt text when present, and sends image metadata to Uhallo only when frontend coverage is needed.
An active Uhallo account and subscription may be required to use the hosted AI service. By connecting Uhallo Sight, site administrators agree to Uhallo’s terms and privacy policy at https://uhallo.com/terms and https://uhallo.com/privacy.
