Overview

AltText.ai is an AI alt text generator focused on website accessibility, ecommerce SEO, and AI search visibility. It scans sites for missing alt text and generates image descriptions that can be used in WCAG- and ADA-oriented workflows, while also helping images become readable to AI systems such as ChatGPT, Claude, and Perplexity.

The product is built for sites that manage many images across CMS, ecommerce, and custom web workflows. It supports multilingual generation, bulk processing, and several implementation paths, including native integrations for major platforms, browser extensions, a JavaScript-based option, and developer APIs.

Core capabilities

Site scan and visibility audit

Scan a site for missing alt text, then generate a breakdown of missing images, affected pages, and an overall AI visibility score. The free scanner is described as crawling up to 25 pages.

Context-aware alt text generation

Generate page-specific alt text that incorporates image context, page intent, product names, brands, and keywords where relevant. The homepage and solution pages emphasize AI-ready descriptions rather than generic captions.

Multilingual output

Work with images in 130+ languages and support additional-language generation as part of the credit model. This helps teams publish alt text for multilingual sites without rewriting every image manually.

Broad integration coverage

Use the product with WordPress, Shopify, WooCommerce, Magento, BigCommerce, Contentful, DatoCMS, Storyblok, browser extensions, Zapier-style connectors, or the API. The product also supports CSV import/export and other workflow tools on the pricing page.

Automatic and bulk workflows

Handle ongoing image updates through automated generation for new uploads and bulk backfilling for existing libraries. The WordPress and ecommerce pages describe automatic processing when images are added or updated.

Multiple implementation options

Add alt text through several delivery methods, including plugins, apps, browser extensions, JavaScript snippets, and developer APIs. The site also mentions InstantAlt for supported web platforms.

Common use cases

Ecommerce catalogs
Generate alt text for product images at the point of upload or update so storefronts stay consistent without manual writing. The ecommerce pages call out Shopify, WooCommerce, Magento, BigCommerce, and Ecwid workflows.
Content management teams
Backfill existing media libraries in WordPress or other CMS setups with bulk-generated alt text. This is useful when a site already has many images missing descriptions.
Accessibility programs
Add alt text to images for accessibility-focused publishing and WCAG/ADA-aligned workflows. The homepage positions the tool as a way to reduce manual writing while improving image descriptions sitewide.
Developers and custom workflows
Use browser extensions, JavaScript snippets, or API access to generate alt text in custom site builds, headless setups, or platforms without a native app. The integrations page also mentions Zapier and similar automation connectors.
AI search visibility
Prepare images for AI search and recommendation systems by giving them descriptive, page-specific text. The product explicitly calls out AI visibility for ChatGPT, Claude, and Perplexity.
