Storyblok Alt Text Generator

Bulk Update Your Entire Asset Library

Already have thousands of images without alt text? Configure your Storyblok settings once, then run our Bulk Updater to process your entire asset library in the background. Select a space, hit import, and come back to fully described images.

Smart Filtering

Skip images that already have alt text to preserve your manual work. Only process what actually needs processing.

Progress Tracking

Real-time progress tracking for every import. See exactly how many images have been processed and review past imports.

Content velocity suffers when teams prioritize alt text
Existing library sits with missing descriptions indefinitely

With AltText.ai

All assets processed automatically in the background
Consistent quality across every image, every language
Content teams stay focused on content, not descriptions
Bulk process existing library to close the gap immediately

Storyblok Alt Text FAQs

FAQ

Two ways: our Bulk Updater processes your entire existing asset library in the background, and webhook automation handles every new upload automatically. Configure your Storyblok region and access token once, and both features are ready to use.

Yes. Any image added through the Visual Editor, asset manager, or API triggers the webhook. The alt text is stored in the asset's alt field and available everywhere the asset is used.

Two events: 'Asset created' (new uploads) and 'Asset replaced' (updated images). You configure these triggers when adding the webhook in Storyblok Space Settings.

Yes. AltText.ai supports custom AI prompts that modify the generation style. For example, you can instruct the AI to always mention your brand name, use specific terminology, or keep descriptions under a certain character limit.

Absolutely. We support 130+ languages through Google Translate and DeepL. Configure your target languages once, and every image gets alt text in all specified languages. Each additional language uses one credit per image.

Standard formats (JPG, PNG, WebP) cost 1 credit per image. Advanced formats (SVG, AVIF) cost 2 credits. You get 25 free credits to start. Plans start at $49/year for 1,200 credits with enterprise plans offering volume discounts.

Configure your Storyblok settings, then go to the Bulk Updater and select a space. Enable 'skip existing' to preserve alt text you've already written. Hit import and it runs entirely in the background—you don't need to stay on the page. Each import is tracked with real-time progress.

Yes. Our AI generates descriptions that meet WCAG 2.1 Level AA guidelines for alternative text. This covers the technical requirement—screen readers receive meaningful context for every image.

Yes. We support all Storyblok server regions: United States, European Union, Canada, Australia, and China. Select your region in the AltText.ai integration settings.

All major formats: JPG, PNG, WebP, GIF, SVG, and AVIF. SVG and AVIF cost 2 credits due to additional processing complexity—but few other tools support them at all.
