Does AltText.ai work with Squarespace?

Yes. The fastest path is InstantAlt — a one-line JavaScript snippet that adds AI-generated alt text to every image on your Squarespace site automatically. Drop it into your Squarespace site's Code Injection area, and every image gets context-aware alt text. No plugin marketplace listing required, works with both Squarespace 7.0 and 7.1.

How do I install InstantAlt on Squarespace?

Squarespace Settings → Advanced → Code Injection → Header. Paste the InstantAlt JavaScript snippet from your AltText.ai dashboard. Save. Every image on your site now gets AI-generated alt text — applied at the page-render layer, no rebuilds, no exports, no manual tagging.

Does it work with Squarespace 7.0 and 7.1?

Yes — InstantAlt runs at the page-render layer regardless of Squarespace version or template. One thing to know: Code Injection is only available on Squarespace's Business plan and above. The Personal plan doesn't support custom code, so InstantAlt isn't an option there. If you're on Personal, upgrading to Business is the path.

What about Squarespace's built-in alt text fields?

Squarespace has alt text fields you can fill in manually for each image. If you've curated alt text there, you can keep using it — those values render in the HTML before InstantAlt runs. For images where you haven't filled in alt text, InstantAlt generates AI-powered descriptions.

What about WCAG compliance?

Generated alt text follows WCAG 2.2 SC 1.1.1 best practices. It's specific, descriptive, and avoids 'image of' filler. See our WCAG alt text guide for the underlying requirements.

AI Alt Text for Squarespace — One Line of Code

Squarespace's image manager won't suggest alt text, and adding it for 500 products by hand is brutal. InstantAlt drops a single JavaScript snippet into Squarespace's Code Injection area — every image on your site gets AI-generated alt text automatically. No plugin needed.

The Squarespace Alt Text Problem

Squarespace is excellent at design and quiet on SEO discipline. The image manager doesn't prompt for alt text on upload. There's no plugin marketplace for accessibility tools. By the time you have 500 products or 200 blog images, the gap is impossible to close by hand.

That gap costs you on three fronts: SEO rankings (Google uses alt text to understand images), accessibility compliance (WCAG SC 1.1.1 requires alt text on every non-decorative image), and AI search visibility (ChatGPT, Claude, and Perplexity read alt text to decide what to cite).

The Fix: InstantAlt for Squarespace

InstantAlt is a one-line JavaScript snippet from AltText.ai. It detects every image on your page at render time and adds AI-generated alt text — without any plugin, export, or manual tagging. Squarespace was built for this exact pattern (Code Injection has been a first-class feature since 2014).

How to Install

Sign up at AltText.ai and add your Squarespace domain in the dashboard.
Copy the InstantAlt snippet (one line of JavaScript).
In Squarespace: Settings → Advanced → Code Injection → Header. Paste. Save.
Done. Every image on your Squarespace site now gets AI-generated alt text.

Setup takes ~60 seconds. No rebuild, no export, no developer required.
