ALTification vs ALTtext.org

ALTification is a WordPress plugin and web service that uses AI to generate keyword-aware alt text, captions, and descriptions for images. It considers the page’s surrounding content and SEO context, and supports bulk site scans as well as targeted scans of pages, posts, and public custom post types. Supported formats include JPG, PNG, WebP, and AVIF. Integrations include Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, WooCommerce, and Advanced Custom Fields. Agency workflows can use before-and-after reports. One credit covers a generation; requesting alt text, a caption, and a description together can use up to three credits per image. The free trial includes 25 credits, three Preview & Refine tests, and one site. Monthly and one-time credit packages are available. Each API key is tied to the first WordPress site where it is used, so additional sites need separate keys. ALTification is operated by A Fine Studio in the United Kingdom. Its privacy policy says submitted images, prompts, and responses are not kept after generation and are not used to train AI models.

ALTtext.org generates written descriptions of images for accessibility. Its web generator accepts images by drag and drop, file selection, or clipboard paste, and can process one or many images. Browser extensions add a generation control to alt-text fields on Bluesky, X/Twitter, Facebook, Instagram, LinkedIn, Threads, Tumblr, Pinterest, Mastodon, and Pixelfed; on other websites, users can invoke generation from an image’s right-click menu. The service is available on the web, as extensions for Chrome, Brave, Edge, other Chromium browsers, Firefox, and Safari on macOS and iOS, and through Mac and iOS apps. ALTtext says the Apple apps bring the tool to desktop and the share sheet. It supports concise and detailed styles, bulk processing, publishing workflows, and API access. Generated descriptions are announced and focused for screen readers; the site says it supports VoiceOver, NVDA, JAWS, and keyboard-only use and builds to WCAG 2.2. The free plan allows 20 ALT texts per day; Individual costs 9.99 USD one-time, Team is $19.99 a month, and Business / API is $99 a month. The maker says images are sent to Google’s Gemini API and are not stored on ALTtext servers.
