About AltCaption
What is AltCaption?
AltCaption is a bulk alt text generator designed for e-commerce teams, content managers, and SEO specialists who need to create descriptive alt text for large product catalogs. It turns image URLs into concise, review-ready alt text that can be copied as TSV and imported into Shopify, WordPress, Webflow, or any custom CMS.
Who is it for?
It is for anyone who manages product feeds, media libraries, or launch checklists with more images than they can describe manually. Whether you are cleaning up a CMS audit, preparing alt text for a store launch, or standardizing descriptions across product variants, AltCaption streamlines the process. It is not for users who need a full AI image suite or one-off alt text for a single image (though the free tier covers that).
Real use cases
Use AltCaption to rewrite missing or vague alt attributes from a CMS export, generate consistent descriptions for product variants, or prepare a spreadsheet of alt text before importing it into your storefront. The tool supports 13 languages and allows you to paste direct image URLs from a CDN or product feed. You can try a few images for free, then upgrade to Pro for bulk generation and TSV export.
Key features
- Bulk generation — Paste image URLs and generate alt text for your entire catalog in minutes.
- TSV export — Copy generated rows as TSV for easy import into CMS, spreadsheets, or storefronts.
- Review-ready output — Avoids keyword stuffing and sales copy, delivering descriptions you can use as-is.
- 13 languages — Generate alt text in English, Spanish, French, German, and more.
- File or URL input — Upload images or paste direct URLs from CDNs, feeds, or CMS exports.
- Free preview — Test a few images before committing to a paid plan.
