Generate Image Alt Text with AltText.Ai Webflow App
AltText.ai is for Webflow site builders who need to fill empty image alt text with descriptions.
AltText.ai is an app that creates descriptions for images in Webflow. You can use them to fill empty alt text fields and support accessibility and image SEO.
Choose sites to authorize for CMS automation, or use the Designer Extension and bulk importer when you want to handle content directly.
Getting started in Webflow
Install AltText.ai and authorize the sites you want it to use. To scan a page you are designing, open the Designer Extension from Webflow’s Apps menu; it finds images without alt text and lets you add descriptions in Webflow.
Features worth knowing
- Automatic generation adds descriptions to image-containing CMS items as they are created or updated, provided their alt fields are empty.
- The Designer Extension scans the page open in the current design session and flags images that lack alt text.
- The bulk importer handles published collections you select and shows the count of empty descriptions before credits are used.
- Bulk imports can be stopped, can skip descriptions already present, and include an overwrite option that starts turned off.
Worth checking first
Automatic generation leaves manually written alt text in place. New descriptions appear on staged content and take effect with your next publish; AltText.ai does not publish your site.
The published Webflow site receives no added code. Installation requires permission to change CMS content and sites, plus access to read your profile.
