See every featureAltGuard solves the tedious task of manually writing alt text for product images. Without alt text, search engines can't read your images and screen readers cannot navigate your store. AltGuard silently runs in the background. Whenever you add or update a product, our AI analyzes the images and writes accurate alt text. You can also run bulk backfills to update your entire catalog in minutes.
Empty alt text is invisible to Google Images. Altly fixes that in one scan: it walks every product, collection, and blog image in your store and writes SEO-friendly alt text using your product title, vendor, type, and tags. Templates are fully editable so the wording stays on-brand. New uploads get tagged automatically via webhooks.
- Automatically writes AI alt text in the background when you update products.
- Run bulk backfills to generate alt text for your entire catalog in minutes.
- Customize description tone, language, and maximum character length for ADA.
- One-click scan tags every product, collection, and blog image in your store.
- Auto-syncs alt text into English, Spanish, French, German, and Arabic locales.
- Editable templates: control wording with {title}, {vendor}, {type} variables.
