AI Alt Text Generator vs Bubuku Media Library

AI Alt Text Generator writes clear, descriptive alt text for every image on your WordPress site — improving accessibility compliance (WCAG 2.2, ADA, Section 508, and the European Accessibility Act) and image SEO at the same time. It works out of the box: activate the plugin and start generating, no API key and no signup required. Every site gets 50 free images per month through the built-in managed credits service. That makes it a fit for small organizations that need accessible, legally compliant websites but don’t want to wrangle developer accounts or AI billing — nonprofits, churches, schools, clinics, and small businesses working toward WCAG / EU Accessibility Act compliance. Alt text is required for accessible, legally compliant websites, and it helps search engines understand your images. But writing it by hand across an entire media library rarely happens — so this plugin does it for you, in bulk or automatically on upload. It produces concise, WCAG-aligned descriptions (no “image of…” filler, sensible length) and can fold in the page context and your SEO focus keyphrase for sharper, more relevant alt text. It pairs perfectly with accessibility audit tools that flag missing alt text — this is the plugin that fills the gaps. How it works — two ways to generate: Managed credits (default, recommended) — No API key, no signup. The plugin connects to the AI Alt Text Generator managed service automatically and gives every site 50 free images per month. Need more? Affordable paid credit plans are available. This uses an external, account-based service (see the disclosure below) and is optional beyond the free tier. Bring your own API key (advanced) — Prefer to run on your own OpenAI or Anthropic account? Add your own API key in the Advanced settings and generation runs at-cost, directly with your provider, with no per-image fees or vendor lock-in. You choose the provider and model. Key Features: – Works out of the box: no API key needed — 50 free images per month on every site – Accessibility & compliance: WCAG-aligned output to support ADA, EAA, and Section 508 requirements – SEO keyphrase integration: automatically weaves in focus keyphrases from Yoast SEO, Rank Math, and SEOPress (without keyword stuffing) – Page-context aware: uses the page/post the image belongs to for more relevant descriptions – Bring your own key (optional): advanced users can plug in their own OpenAI or Anthropic key — any vision-capable model, no lock-in – Bulk Processing: generate alt text for your whole library at once, or automatically on upload – Custom Prompts: tailor the AI prompt to your brand and needs – Multi-Language Support: generate alt text in many languages – Testing Feature: preview prompts before applying them to images – WP-CLI Support: bulk-generate from the command line – Developer-friendly: extensible via action/filter hooks for custom integrations and add-ons WP-CLI: The plugin registers a wp ai-alt-text command suite, making it easy to automate alt text generation across one or many sites. # Bulk-generate alt text for all images missing it (uses managed credits by default) wp ai-alt-text generate # Optional: configure your own provider and API key (advanced) wp ai-alt-text activate --provider=openai --key=sk-xxxxxxxx # Regenerate alt text for specific attachments wp ai-alt-text generate --ids=12,34,56 --force # Preview what would be processed without calling the API wp ai-alt-text generate --limit=20 --dry-run # Show current configuration and coverage wp ai-alt-text status A typical install-and-generate workflow needs no key at all: wp plugin install ai-alt-text-generator --activate wp ai-alt-text generate --yes New in Latest Version: – Managed credits are now the default: generate alt text with no API key and no signup — 50 free images per month on every site – Bring-your-own OpenAI/Anthropic key moved to an “Advanced” option for users who prefer to run on their own account – WCAG-aligned output, SEO focus-keyphrase integration (Yoast / Rank Math / SEOPress), and page-context awareness – Optionally set the image Title, Caption, and Description from the generated alt text – Future-proof model handling (no hard-coded model versions; configurable defaults) Important: This plugin uses an external AI service to generate alt text — either the optional managed-credit service (account-based, free tier plus paid plans) or your own OpenAI/Anthropic key. See the External Service Usage Disclosure below. AI Alt Text Generator Pro (optional upgrade) Need automation at scale? The optional Pro add-on builds on this free plugin with: – WooCommerce product context for commerce-aware, SEO-rich alt text – Scheduled background scans that describe new and existing images automatically – A coverage analytics dashboard to track your progress toward 100% – Automatic updates and priority support Learn more about Pro — the free plugin remains fully functional on its own. External Service Usage Disclosure This plugin relies on external AI services to generate alt text. In all cases, data (images and their metadata) is sent to an external service for processing. The plugin does not store your images or generated alt text on our servers beyond what is needed to return your result. Managed credits service (default) By default the plugin uses the AI Alt Text Generator managed credits service so it works with no API key. On activation, the plugin automatically connects your site to obtain a free account (50 images per month) — this registers your site with the external service and requires an account. Images to be described are sent to this service for processing. Use beyond the free monthly tier requires a paid credit plan. The service is operated via https://store.lessbutmore.ai?utm_source=plugin&utm_medium=readme&utm_campaign=disclosure — please review the site for its terms and privacy policy. You can disable managed credits in the plugin settings and use your own API key instead. Bring-your-own-key providers (optional, advanced) If you add your own API key, images are sent to the provider you select: – OpenAI: For more information, please review the OpenAI Terms of Use and Privacy Policy – Anthropic: For more information, please review the Anthropic Terms of Service and Privacy Policy You choose which path to use and are only required to agree to the terms of the service you actually use.

Bubuku Media Library helps content and marketing teams audit, monitor and optimize images in WordPress. Track file sizes, identify missing alt text, export reports, receive email summaries and connect AI assistants through MCP. New in version 1.3.0: Bubuku Media Library includes an MCP Server that allows compatible AI assistants and developer tools to interact with your WordPress Media Library through a secure endpoint with role-based permissions. You can: Sort the Media Library by file size to easily identify large files. Filter images that don’t have alternative text (alt text). Use size-based filters (for example: optimal size, medium size, large size) to prioritize which images to optimize first. Run a Bulk Action in the Media Library to calculate file sizes for existing uploads. Export CSV reports including file size, format (MIME type), URL, alt text, image date, post title and post URL — ideal for audits or sharing with your team. See a summary of your Media Library in a dashboard widget, including how many images are heavy or missing alt text. Configure weekly or monthly email reports so you can monitor the optimization status of your images without logging into WordPress. Connect MCP-compatible AI assistants to your Media Library using role-based permissions and configurable abilities. More information (in Spanish) about how the plugin works: How to know if we have to reduce weight to the image and Alt SEO attribute AI & MCP Integration Bubuku Media Library includes a built-in MCP Server that allows compatible AI assistants and development tools to securely interact with your WordPress Media Library. Available MCP abilities include: Listing media library attachments. Reviewing image metadata and alt text coverage. Exporting media audits to CSV. Accessing media library summary metrics. Triggering reports and diagnostics. Managing media accessibility workflows. Each ability can be enabled or disabled individually and restricted to a minimum WordPress role. This allows you to safely connect AI assistants like Claude Desktop, Codex, Cursor and other MCP-compatible clients to audit images, review missing alt text, generate reports and automate media management workflows, while keeping permissions under your control. Typical use cases include: Finding images without alt text. Exporting media audits for content reviews. Checking image size distribution. Generating accessibility reports. Integrating WordPress media workflows with AI assistants. Automating repetitive media library review tasks. Quick Start From your server (SSH), move the plugin folder to the plugins directory: wp-content/plugins/bubuku-media-library/ Activate the plugin via the WordPress admin or using WP-CLI: wp plugin activate bubuku-media-library (Optional) Run the bulk action in Media > Library to calculate file sizes for existing images. Evaluate results Recommended Tools – Lighthouse (in Chrome DevTools) — Analyze image weight and format, as well as the use of alternative text (ALT). – WebPageTest — Check how images affect real-world load times. – Squoosh — Compare visual quality and file size savings when optimizing images. – WAVE Accessibility Tool — Verify whether images are missing ALT attributes or if the alternative texts are descriptive. Evaluation Guidelines – Identify images without ALT text or with excessive file size before running external tests. – After replacing large images or adding ALT text, repeat your evaluations to confirm improvements. – Evaluate both new and existing content — not only the most recent uploads. – Define an internal size limit (for example, 200 KB per image) and monitor it regularly. – Keep in mind that accessibility also affects SEO and overall user experience.
