Alt Audit

Overview

Alt Audit is an AI alt-text generator and website auditing service for people responsible for image accessibility across websites. It is strongest for consultants, agencies, and WordPress teams that need site scans, bulk processing, and shareable reports. Page-level checks make it more than a one-image-at-a-time generator, though its monthly credit limits matter for larger workloads.

It scans real pages for missing or weak image descriptions and generates alt text with Google Gemini 2.5 Flash. Alt Audit describes its image checks as aligned with WCAG Level A and says its output meets WCAG 2.2 standards; those checks can support accessibility work, but do not replace reviewing whether each description suits its context. PDF reports and summaries give teams a concrete way to communicate findings to clients or stakeholders.

Key features

Audits and image processing

Bulk processing and page scans suit website cleanup better than a tool focused only on isolated uploads. Each image processed uses one credit, and supported formats are JPEG, PNG, GIF, and WebP. That per-image accounting is straightforward, but the monthly allowance sets a hard ceiling on how much work a plan can cover.

WordPress and API workflows

The WordPress plugin can generate alt text as images are uploaded and bulk process existing media-library images, making it a practical fit for WordPress teams working through both new and older content. API access supports custom integrations, but it is reserved for Agency rather than the lower paid plans.

Privacy and support

Alt Audit says images are accessed temporarily by URL and discarded after processing, while image URL references and generated alt text are stored. Its privacy policy also states that it encrypts data in transit and at rest, conducts regular security audits, and complies with GDPR and CCPA. Free Starter includes community support; paid plans include priority email support.

Pricing

Alt Audit uses a freemium model. Starter costs $5 a month and includes 800 credits/month, bulk processing, priority email support, and export capabilities. It is the lowest-cost paid option for users who need regular batches and reports, but its allowance may be tight for broad site audits.

Pro costs $19 a month and provides 3,000 credits/month with everything in Starter. It suits teams with more recurring image work; the listed benefits do not add a different workflow beyond the higher allowance. Agency costs $49 a month and includes 8,000 credits/month, everything in Pro, API access, white-label options, and a dedicated account manager. Those extras make it the relevant tier for agencies delivering branded work or integrating the service into their processes.

Free Starter costs nothing and provides 25 credits/month forever, AI alt-text generation, the WordPress plugin, basic analytics and dashboard, and community support. It is useful for a small ongoing workload, but the 25-image monthly ceiling and lack of paid-plan priority support limit its role for client or site-wide work. Credits reset monthly and unused credits do not roll over, so plans are a poor fit for demand that comes in occasional large bursts.

Platforms

Alt Audit is available on web and through an API, with a WordPress plugin for upload and media-library workflows. API access is included with Agency. The plugin and web service make WordPress publishing workflows a strength; teams on lower tiers should not assume API integration is included.

Who it's for

Accessibility consultants and SEO professionals can use page scans and report exports to review sites and share findings. Agencies may value white-label options and a dedicated account manager on Agency. WordPress teams can use the plugin to process uploads and existing media. It is less compelling for users who need only occasional descriptions, have image volumes beyond the monthly credit caps, or require API access without the Agency plan.

Pros and cons

• Pros: Scans real pages for weak or missing alt text, extending the workflow beyond single-image generation.
• Pros: WordPress upload generation and bulk media processing address both ongoing publishing and cleanup.
• Pros: PDF reports and summaries support client and stakeholder communication.
• Cons: Monthly credits expire at reset, so unused capacity cannot cover a later busy period.
• Cons: API access is limited to Agency, which may put custom integrations out of reach for smaller teams.
• Cons: Free Starter's 25 credits/month is a narrow allowance for site-wide work.

Alternatives

AI Alt Text Generators is a broader category directory for comparing tools. Consider AltTextLab instead if you want 25 free monthly credits with unlimited websites, 20+ integrations and API access, and 130+ languages. Altvisor offers 50 images/month and one website on its free plan, with a web-only workflow. AutoAlt.ai has a free tier with 50 credits/month and a free trial, and supports API, extension, and web access.

Uix Page Builder is a free self-hosted and web option. AI Alt Text Generator offers 50 images/month per site on its free managed-credits plan. AI Image Alt Text Generator is a free self-hosted plugin, though it requires a configured AI provider and providers may charge per API request. Alt Text Studio offers pay-as-you-go credits as well as a $4 a month Starter plan with 100 credits/month. AltText.ai offers a 3.00 USD one-time pack of 50 credits, with no subscription.

Verdict

Alt Audit is a strong fit for consultants, agencies, and WordPress teams that need page-level image checks alongside generation, bulk processing, and report exports. Its most persuasive advantage is the connected audit-to-report workflow; its main drawback is that credits expire monthly and API access requires Agency. Choose it when those workflows matter, and look elsewhere if you need a larger free allowance or API access on a lower-cost plan.
