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: <a href="https://bialty.com/" rel="nofollow ugc">bialty.com</a>
<h4>Quick product facts</h4>
<ul>
<li>Product type: WordPress alt text automation plugin</li>
<li>How it works: injects alt text at render time in frontend HTML</li>
<li>What it does not do: does not rewrite Media Library metadata</li>
<li>Rule sources: focus keyword, title, image filename, combined modes, manual override</li>
<li>SEO plugin support: Yoast SEO, Rank Math, All in One SEO</li>
<li>WooCommerce support: available in Pro</li>
<li>AI image analysis: not included</li>
<li>External API calls: none</li>
<li>Reversible: yes, instantly</li>
</ul>
<h4>What Bialty does</h4>
Bialty applies a deterministic rule to images when a page is rendered.
Depending on your settings and plan, Bialty can use:
<ul>
<li>Focus keyword from Yoast SEO</li>
<li>Focus keyword from Rank Math</li>
<li>Primary keyphrase from All in One SEO (AIOSEO)</li>
<li>Post title</li>
<li>Product title</li>
<li>Cleaned image filename</li>
<li>Combined values such as keyword + title</li>
<li>Custom manual alt text set per post, page, or product</li>
</ul>
Bialty is useful for:
<ul>
<li>adding alt text where none exists</li>
<li>replacing existing alt text according to a defined rule</li>
<li>standardizing alt text logic across a site</li>
<li>covering WordPress posts and pages</li>
<li>extending the same logic to WooCommerce and custom post types in Pro</li>
</ul>
<h4>What Bialty does not do</h4>
Bialty does not do the following:
<ul>
<li>it does not rewrite Media Library metadata</li>
<li>it does not permanently write generated alt text into the database</li>
<li>it does not visually analyze images</li>
<li>it does not call any external AI API</li>
<li>it does not generate unique descriptive captions for each image based on computer vision</li>
<li>it does not process headers, footers, sidebars, or widget images by default</li>
</ul>
This distinction matters: Bialty is a contextual rule engine, not an AI vision plugin and not a bulk Media Library rewriting plugin.
<h4>Why Bialty is different</h4>
Most image alt text plugins follow one of two models:
<ol>
<li>
Bulk rewrite model 
They rewrite alt text inside the Media Library or database.
</li>
<li>
AI vision model 
They send images to an external API and generate descriptive text from image analysis.
</li>
</ol>
Bialty follows a third model:
<ol>
<li>Dynamic contextual injection model 
It injects alt text into frontend HTML at render time using rules and signals already available in WordPress.</li>
</ol>
This gives Bialty a distinct profile:
<ul>
<li>Dynamic frontend injection — alt text is added to rendered HTML</li>
<li>No Media Library rewrite — stored metadata remains unchanged</li>
<li>Instant reversibility — disable the plugin and the injected alt text disappears</li>
<li>No external API — no quota, no per-image cost, no API dependency</li>
<li>Deterministic behavior — same rule, same output</li>
</ul>
<h4>SEO plugin compatibility</h4>
Bialty reads keyword data from the SEO plugin already active on the site.
Supported integrations:
<ul>
<li>Yoast SEO — reads the focus keyword field</li>
<li>Rank Math — reads the focus keyword field</li>
<li>All in One SEO (AIOSEO) — reads the primary keyphrase</li>
</ul>
If no supported SEO plugin is active, Bialty can still use titles or image filenames as the alt text source.
<h4>Free edition</h4>
The free edition covers the core WordPress use case.
Included in Free:
<ul>
<li>Posts</li>
<li>Pages</li>
<li>Missing alt text rule</li>
<li>Existing alt text rule</li>
<li>Manual override per post or page</li>
<li>Disable on homepage</li>
<li>Debug mode</li>
<li>Delete settings on deactivation</li>
</ul>
Free is intended for standard content sites that want dynamic alt text on posts and pages.
<h4>Commercial edition (Pro)</h4>
The commercial edition extends Bialty to larger and more complex WordPress stacks.
Included in Pro:
<ul>
<li>Custom post types</li>
<li>WooCommerce support</li>
<li>Product page coverage</li>
<li>Product gallery controls</li>
<li>Related products coverage</li>
<li>Blacklist / exclusion rules</li>
<li>Add Site Title</li>
<li>Broader rule combinations</li>
<li>Product-level manual override</li>
</ul>
Pro is intended for stores, agencies, and sites using WooCommerce or custom content models.

<h4>7-day paid trial</h4>
Bialty Pro offers a 7-day paid trial.
Important:
<ul>
<li>the trial is not free</li>
<li>payment is required at checkout</li>
<li>the trial gives access to the commercial scope so the plugin can be tested on a real site, theme, builder, and WooCommerce stack</li>
</ul>
This is useful when compatibility must be validated on a production-like environment.
<h4>Builder and editor compatibility</h4>
Bialty works when content is rendered through the standard WordPress frontend pipeline.
Documented compatible editors and builders include:
<ul>
<li>Gutenberg</li>
<li>Classic Editor / TinyMCE</li>
<li>Elementor</li>
<li>SiteOrigin Page Builder</li>
</ul>
Important technical note:
Bialty relies on WordPress rendering filters such as <code>the_content</code>, <code>post_thumbnail_html</code>, 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:
<ul>
<li>Beaver Builder edit mode — Bialty is disabled in builder edit mode to avoid conflicts</li>
</ul>
Outside the default scope:
<ul>
<li>header images</li>
<li>footer images</li>
<li>sidebar images</li>
<li>widget images</li>
<li>any image output that bypasses the supported frontend rendering flow</li>
</ul>

<h4>How to verify Bialty is working</h4>
Bialty changes the rendered frontend HTML.
It does not change the Media Library field.
To verify Bialty correctly:
<ol>
<li>Open the published page in a browser</li>
<li>Do not rely on the editor view</li>
<li>Clear all cache layers if caching is active</li>
<li>Inspect the <code><img></code> element in the rendered page</li>
<li>Check the <code>alt</code> attribute</li>
</ol>
If the <code>alt</code> 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.

<h4>Performance profile</h4>
Bialty is designed to stay lightweight.
It does not:
<ul>
<li>run a bulk background process</li>
<li>queue database rewrite jobs</li>
<li>call external APIs</li>
<li>add per-image API latency</li>
</ul>
Instead, Bialty processes the rendered page at request time using local WordPress context. Actual impact depends on theme, builder, caching, and page complexity.
<h4>Accessibility and editorial note</h4>
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.
<h4>Languages</h4>
Bialty is translated into 6 languages:
<ul>
<li>English</li>
<li>French</li>
<li>Spanish</li>
<li>Portuguese</li>
<li>German</li>
<li>Russian</li>

<h4>About the publisher</h4>
BIALTY is developed by <a href="https://pagup.com/" rel="nofollow ugc">Pagup</a>, 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 <a href="https://pagup.com/en/glossary/digital-readability/" rel="nofollow ugc">digital readability</a> instead of creating silent blind spots.

Bulk Auto Image Alt Text (Alt tag, Alt attribute) optimizer (image SEO)


Ultra misleading title, which is unacceptable. 



Alt text for images attached to WooCommerce products is available only in paid version. The title is misleading, and this "detail" is nowhere to be found in the extremely long plugin description. 



It's ok to have a PAID version, but you have to be clear in the title and description about which features are included in the FREE version, and which on the PAID. This problem is highlighted my multiple users but you still have not updated the plugin description, instead you argue with them in the comments. Please tell the truth about your features and the 1-star reviews will stop coming.


Misleading title, WooCommerce is supported only in paid version


I like what this plugin does (the output is correct), but I wish it wrote to the database rather than run in the front end on every page load. For that reason, I won't be using it myself.



Another good thing is that it lets you choose if you want to overwrite existing values or not. Very important option.


Good plugin, missing 1 function

Two things I absolutely needed this plugin for was identifying and automatically, bulk updating image alt tags for custom post types and top be able to dynamically create the alt text from the filename.

On the "Welcome" splash page, the first thing I see is:

"GET BIALTY PRO TO ENABLE THESE FEATURES:
- Add Post Title or Image Name as Alt Attribute

I thought, "Well, the free version can't do that, but let's see what it can do".

But, then as soon as I'm stepping through the "tour", and I realize that the free version only works on "Post" and "Page", but not on any custom post types. I feel duped.


Although, I wouldn't say that the plugin name is deceptive, it does appear that the marketing department has buried the lede and failed to clearly (not opaquely) indicate that most features WooCommerce sites, News Sites, Directory sites, etc. need are only available in the Pro version.

Also, the fact that there are no YouTube tutorials on how to use this plugin gives one pause.

I've got nothing against premium plugins, but it seems like there is definitely something deceptive about how this plugin is marketed. I cant' quite put my finger on it.

BIALTY Free version doesn't work on custom post types (CPT)

Automatic alt text for WordPress and WooCommerce. Dynamic, reversible, and based on your existing SEO context from Yoast, Rank Math, or AIOSEO.
