The record

Purpose: ALTtext generates written descriptions of images for accessibility.
Image input: The web generator accepts images by drag and drop, file selection, clipboard paste, and supports one or many images.
Browser storage: The website says generated results are saved only in the current browser and nothing is uploaded or shared.
Platform integrations: The extension adds a generate button in ALT text fields on Bluesky, X/Twitter, Facebook, Instagram, LinkedIn, Threads, Tumblr, Pinterest, Mastodon, and Pixelfed.
Other websites: On other sites, the extension can generate ALT text for an image from its right-click context menu.
Browser support: The extension is available for Chrome, Brave, Edge, other Chromium browsers, Firefox, and Safari on macOS and iOS.
Apple app: ALTtext says its Mac and iOS app brings the tool to desktop and the share sheet.
Accessibility support: The site says it supports VoiceOver, NVDA, JAWS, and keyboard-only use, and builds to WCAG 2.2.
Screen reader behavior: Generated descriptions are announced and focused for screen readers to read aloud immediately.
Image processing: The privacy policy says images are downscaled in the browser, sent to Google's Gemini API for description, and are not stored on ALTtext's servers.
Data sharing: The privacy policy names Google, Stripe, Netlify, and Resend as services that receive or store data for image generation, payment, hosting and records, or license emails.
Privacy practices: ALTtext says it has no accounts, does not sell data, and does not use advertising or cross-site tracking.
Data retention: The privacy policy says usage counts reset daily, images are not retained, and license records are kept while a license is active and for a reasonable period afterward.
Maker: The privacy policy says ALTtext is operated by Twilightscapes.
