Your Images Have a Problem
Compliance liability
Missing alt text creates an accessibility gap. WCAG expects text alternatives for informative images, and enforcement pressure is increasing. One audit can cost more than a year of AltText.ai.
AI visibility gap
AI systems like ChatGPT and Perplexity can't see images—they read alt text. If your images have no descriptions, or generic ones like "product image 1", you're invisible to the fastest-growing research channel on the internet.
Scale problem
Writing alt text manually doesn't scale. Your backlog grows with every image published. We fix this automatically in 130+ languages—using our WordPress plugin, Shopify app, or any platform.
Check your AI visibility score
Our free scanner crawls up to 25 pages and shows you exactly which images ChatGPT, Claude, and Perplexity can't see — with a full breakdown of missing alt text, affected pages, and your overall AI visibility score.
AI Visibility
Why Alt Text Matters for AI Search
ChatGPT and Perplexity read text, not pixels. No alt text means invisible products.
LLMs surface brands they can parse and trust. Images without strong alt text become invisible to retrieval and summarization systems.
AltText.ai generates keyword-aware, page-specific alt text in 130+ languages so your products show up in AI answers worldwide—with the right context.
Page Intent Alignment
Alt text aligned to page intent, product attributes, and categories
Bulk Generation
Bulk generation across libraries, CMS entries, and product catalogs
Quality Checks
Quality checks for missing, duplicated, or vague alt text
Consistent Naming
Consistent naming for brands, SKUs, locations, and services
Three Steps to Automatic AI Visibility
Install Once
Add our plugin to WordPress or Shopify (takes 2 minutes). Or paste one line of JavaScript on any website. That's the only setup you'll ever do.
We Analyze Every Image
Our AI automatically analyzes each image on your site—product photos, blog graphics, team headshots—and generates accurate, detailed descriptions. No manual work required.

AI Agents Can Finally See You
When ChatGPT, Perplexity, or any AI system crawls your site, they can now understand what your images show. You become visible to AI research—automatically, and permanently. No ongoing maintenance.
Flexible Integrations
Whether you are a content creator, agency, business owner, or developer, AltText.ai can make your job easier, and your website better.
Automatically generate alt text for every new image you add to your media library. Plus, repair all your existing images with our bulk updater. AltText.ai for WordPress does it all.
Our Shopify app, WooCommerce integration, and Magento extension intelligently add your product data into the generated alt text.
Use our native app for Contentful or plugin for DatoCMS to seamlessly add AI-generated alt text to your images within the CMS. We even have a Zapier integration to handle other platforms!
Generate alt text for individual images, or import directly from CSV, Dropbox, Cloudinary, or Pinterest. Our Developer API lets you add SEO alt text anywhere in your application.
The AltText.ai Chrome Extension and Firefox AddOn let you right-click on any image and get alt text to copy and paste. Use them with your Squarespace site, Webflow project, or any other web page.
We offer pre-built connectors for Zapier, Pabbly, Albato, and SureTriggers. You can hook these up to hundreds of other supported systems to build a fully automated alt text generation workflow.

5 websites optimised with ALT text in an afternoon
Thanks for saving us hours of work. We have optimised 5 of the sites we run just today! That is over 1550 images so far to say we are impressed is an understatement
Great Tool for Alt Text
The API works great and is very quick. I processed over 200 images in less than 5 minutes and all of the 'alt' text was exceptionally accurate.
A great tool - well done 10/10
Very helpful tool for bloggers
AltText.ai has become an essential tool in my website optimization toolkit. As someone who values both SEO and accessibility, I was thrilled to discover this AI-powered solution that generates image alt text effortlessly. The accuracy of the generated alt text is impressive - it captures relevant details from images without any human intervention required.
This is VERY good
I have multiple client websites with thousands of images that do not have alt text. We have tried code that "assigns" alt text but they are clumsy.
Alttext.ai is AI driven and VERY Good. I burned through my 2000 first month allotment quickly.
