Bialty is a WordPress alt text automation plugin. Bialty adds alt text to images dynamically in the rendered frontend HTML. It does not rewrite the Media Library. It uses SEO and editorial context already present in WordPress, such as focus keywords, post titles, product titles, or cleaned image filenames. Bialty is designed for site owners who want broad alt text coverage without destructive database changes, bulk rewrites, or external AI APIs. 👉 Official documentation and product site: bialty.com Quick product facts Product type: WordPress alt text automation plugin How it works: injects alt text at render time in frontend HTML What it does not do: does not rewrite Media Library metadata Rule sources: focus keyword, title, image filename, combined modes, manual override SEO plugin support: Yoast SEO, Rank Math, All in One SEO WooCommerce support: available in Pro AI image analysis: not included External API calls: none Reversible: yes, instantly What Bialty does Bialty applies a deterministic rule to images when a page is rendered. Depending on your settings and plan, Bialty can use: Focus keyword from Yoast SEO Focus keyword from Rank Math Primary keyphrase from All in One SEO (AIOSEO) Post title Product title Cleaned image filename Combined values such as keyword + title Custom manual alt text set per post, page, or product Bialty is useful for: adding alt text where none exists replacing existing alt text according to a defined rule standardizing alt text logic across a site covering WordPress posts and pages extending the same logic to WooCommerce and custom post types in Pro What Bialty does not do Bialty does not do the following: it does not rewrite Media Library metadata it does not permanently write generated alt text into the database it does not visually analyze images it does not call any external AI API it does not generate unique descriptive captions for each image based on computer vision it does not process headers, footers, sidebars, or widget images by default This distinction matters: Bialty is a contextual rule engine, not an AI vision plugin and not a bulk Media Library rewriting plugin. Why Bialty is different Most image alt text plugins follow one of two models: Bulk rewrite model They rewrite alt text inside the Media Library or database. AI vision model They send images to an external API and generate descriptive text from image analysis. Bialty follows a third model: Dynamic contextual injection model It injects alt text into frontend HTML at render time using rules and signals already available in WordPress. This gives Bialty a distinct profile: Dynamic frontend injection — alt text is added to rendered HTML No Media Library rewrite — stored metadata remains unchanged Instant reversibility — disable the plugin and the injected alt text disappears No external API — no quota, no per-image cost, no API dependency Deterministic behavior — same rule, same output SEO plugin compatibility Bialty reads keyword data from the SEO plugin already active on the site. Supported integrations: Yoast SEO — reads the focus keyword field Rank Math — reads the focus keyword field All in One SEO (AIOSEO) — reads the primary keyphrase If no supported SEO plugin is active, Bialty can still use titles or image filenames as the alt text source. Free edition The free edition covers the core WordPress use case. Included in Free: Posts Pages Missing alt text rule Existing alt text rule Manual override per post or page Disable on homepage Debug mode Delete settings on deactivation Free is intended for standard content sites that want dynamic alt text on posts and pages. Commercial edition (Pro) The commercial edition extends Bialty to larger and more complex WordPress stacks. Included in Pro: Custom post types WooCommerce support Product page coverage Product gallery controls Related products coverage Blacklist / exclusion rules Add Site Title Broader rule combinations Product-level manual override Pro is intended for stores, agencies, and sites using WooCommerce or custom content models. 👉 Compare Free vs Pro 👉 WooCommerce documentation 7-day paid trial Bialty Pro offers a 7-day paid trial. Important: the trial is not free payment is required at checkout the trial gives access to the commercial scope so the plugin can be tested on a real site, theme, builder, and WooCommerce stack This is useful when compatibility must be validated on a production-like environment. Builder and editor compatibility Bialty works when content is rendered through the standard WordPress frontend pipeline. Documented compatible editors and builders include: Gutenberg Classic Editor / TinyMCE Elementor SiteOrigin Page Builder Important technical note: Bialty relies on WordPress rendering filters such as the_content, post_thumbnail_html, and WooCommerce-specific frontend hooks. If a theme, builder, widget, or template bypasses the standard frontend flow, Bialty may not affect those images. Known special case: Beaver Builder edit mode — Bialty is disabled in builder edit mode to avoid conflicts Outside the default scope: header images footer images sidebar images widget images any image output that bypasses the supported frontend rendering flow 👉 Compatibility details How to verify Bialty is working Bialty changes the rendered frontend HTML. It does not change the Media Library field. To verify Bialty correctly: Open the published page in a browser Do not rely on the editor view Clear all cache layers if caching is active Inspect the element in the rendered page Check the alt attribute If the alt attribute matches the configured rule, Bialty is working. If the Media Library still shows an empty or unchanged alt field, that is normal. Bialty does not write generated values back to stored metadata. 👉 Full troubleshooting guide Performance profile Bialty is designed to stay lightweight. It does not: run a bulk background process queue database rewrite jobs call external APIs add per-image API latency Instead, Bialty processes the rendered page at request time using local WordPress context. Actual impact depends on theme, builder, caching, and page complexity. Accessibility and editorial note Bialty helps automate alt text coverage and consistency. However, context-specific manual alt text may still be preferable when highly descriptive, accessibility-focused, or editorially precise alt text is required for a particular image. Bialty is best understood as a scalable rule-based automation layer, not as a replacement for manual judgment in every image context. Languages Bialty is translated into 6 languages: English French Spanish Portuguese German Russian Links Official site and documentation Features How it works WooCommerce support Compatibility Pricing and plans FAQ Troubleshooting Blog About the publisher BIALTY is developed by Pagup, a digital readability firm based in Quebec, Canada. Alt text is not just an accessibility requirement. It is a semantic signal that helps search engines and AI systems understand what your images represent and how they relate to your content. Missing or generic alt texts create interpretive gaps — the system sees an image but cannot determine its role, its subject, or its relationship to the page. BIALTY automates alt text management so that your visual content contributes to your site’s overall digital readability instead of creating silent blind spots.
