ALTtext.org vs easyAlt

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.
