Free Alt-Text Health Score
Paste any page of your website. In seconds for most pages, and up to a minute for pages built with JavaScript, you will see how many of its pictures say nothing to a blind visitor, whose phone or computer reads the page aloud. That software is called a screen reader. You can hear what the page says now, and what it would say once the pictures are described. No sign-up. Nothing on your site is changed.
We only read the page's HTML to find images. We never alter your website.

What this page sounds like
Where this sits legally
Whatever you put here comes to us with your report. It helps us answer you properly.
This page looks JavaScript-built. Images added by scripts are invisible to this scan, so treat the score as a floor rather than the full picture.
Optional. Leave blank to skip the comparison.
Thank you. Your request is in: a confirmation with your result link is on its way, and your fuller report is being prepared.
Fix these with alt text written for your brand and saved into your own site. Ask about a pilotNarraSight writes the descriptions into your CMS, or hands you the text as a file you keep. Never a runtime overlay. The score itself: missing or junk alt text (filenames, placeholders, labels like “image”) scores nothing, alt text that is present but weak scores half, and alt text that says what the image shows scores in full, against WCAG 2.2 SC 1.1.1. For a sample of images an AI model also reads the picture itself and checks the alt text against it, and where the text falls short you see the alt NarraSight would write instead. Every result also says what this page would score once the flagged images are described, which is the same arithmetic run forwards rather than a forecast. The full method, and everything the score does not claim, is set out on the How the score works page, linked in the footer below.
What the check covers
Every image on the page, judged for what a screen reader gets
Missing alt text
Images with no alt attribute at all: a screen reader says nothing useful, often just the file name, and image search has nothing to go on.
Poor or generic alt text
Filenames, placeholders, marketing filler, text copy-pasted across images, or text unrelated to the page it sits on.
The rewrite we would ship
For the worst images, the description NarraSight would write instead, in the page's own subject and tone, checked against the picture itself.

The full fix list, by email
Leave your email and every flagged image opens, each with the description NarraSight would write, with the report sent to you to keep.
NarraSight writes it back
The platform describes the images on your site in context, holds anything uncertain for review, and writes approved alt text into your CMS with a record of every change. Ask about a pilot if you would like it run on your own site.
