GotAlt checks whether the alt text on your pages is true of the picture, not just present. Scan up to three pages free for 16 rule checks, then run the deep AI audit to have a vision model compare each image with its alt text. Add weekly monitoring and you hear about a break at the next check, not months later.

These are the failures any scanner can detect: attributes that are missing or malformed.
Free, one a day. Rule engines can only check whether alt text exists. We fetch your images and check whether the alt text is true, plus whether your link text and headings make sense to someone who can't see the page.

Automated checks cover part of WCAG. Keyboard navigation and focus visibility need a person testing the page, and color contrast needs the rendered page: our free bookmarklet measures it on any live page. Treat this report as a strong starting point, not a compliance certificate; no automated tool can promise one. Our full accessibility checklist covers both kinds.
This scan read up to three pages. Check up to 50 pages once, $49, no subscription, and get a list of the images whose alt text may not match the picture. To have your pages checked every week instead, with an email when a check finds a new critical or serious issue, monitor your pages every week from $29/mo. What each one includes and what it leaves out is on the pricing page. Our privacy policy explains what we keep and for how long.
Up to 250 pages costs $149. Both sizes include a fix sheet with drafted alt text for each flagged image, and one re-check within 30 days. See a sample fix sheet (CSV file)
Two of the eight images in our sample report, a shop we broke on purpose. Both have alt text, so a rule that only reads the HTML passes them. The vision model looked at the pictures.
Alt text "Our team at the 2025 trade show"
Inaccurate AI-generated The image shows a close-up of a black rubber outsole. The alt text describes a different photograph, a common result of copying markup between pages.
Suggested Close-up of the boot's lugged rubber outsole
Alt text alt="" (empty)
Wrongly marked decorative AI-generated The image shows an orange two-person tent pitched on grass. An empty alt tells a screen reader to skip the image, and here the image is the product.
Suggested Orange two-person tent pitched on grass
The verdicts, the descriptions of the images and the suggestions are written by an AI model (Claude, from Anthropic) and can be wrong, so check each one against the image. How GotAlt uses AI
People who can't see a picture depend on its alt text to know what it shows. GotAlt opens up to six images on each monitored page and checks that each description is true of its picture. When a redesign or a swapped product photo makes one wrong, the next weekly check finds it.
A redesign, a theme update or a swapped product photo can leave an image description wrong, and nothing on the page says so. The weekly check emails you when it finds a new critical or serious issue, with the page and what we found, so you can act while the cause is still easy to trace.
A client, a colleague or your developer wants to know what was checked and when. Each issue in your dashboard keeps its history: when it was first seen, when it was last confirmed and what the recent checks on that page did. Export the list as a CSV file or print a report. It records what was checked and when. It is not a certificate.
Selling to the EU? The European Accessibility Act has applied since June 28, 2025, and enforcement has begun: French advocacy groups put four grocery retailers on formal notice in July 2025, and in June 2026 a French court ordered one of them to make its website and app accessible (reported by Handicap.fr). The Act covers most companies selling online to EU consumers, wherever they're based; microenterprises providing services are exempt. Read our EAA guide, answer a few questions in which accessibility laws apply to me? or compare accessibility laws by country. This is general information, not legal advice.
In the US, federal website-accessibility filings under the ADA rose from 2,452 in 2024 to 3,117 in 2025 (Seyfarth Shaw's ADA Title III tracker, 2025). Missing alt text and unlabeled form fields are among the most common failures WebAIM finds on home pages (WebAIM Million), and both are what this scan finds. Public-sector sites have their own deadline: Title II now lands in April 2027 for larger entities and April 2028 for smaller ones. Not sure what a rule means? The 86 WCAG 2.2 success criteria are explained one by one.

Most automated accessibility testing is built on open-source rule engines. They are fast and free to run, which is why unlimited rule-based scanning is widely available. But they can only answer one kind of question.
alt attribute?label?Answerable by reading the HTML. By common estimates, roughly a third of WCAG (how we count).
Answerable only by judgment. We fetch the real images and read the real content.
Every deep audit fetches your images and puts each one through a vision model, page by page. That is why GotAlt prices by monitored page rather than selling unlimited scans, and why it finds problems a rule engine passes. The longer argument, including where rule engines beat us.
Agencies get a service they can offer every client. In-house teams get a standing answer for a manager, a colleague or a developer who asks where the site stands and what changed.
Give each client a weekly check of their pages and you walk into every conversation knowing what was checked, what changed and what is fixed. One pool of pages (100 included, then $1.30 each) covers as many client sites as you manage, and each client's share of the pool is shown so you know what to charge them.
"14 images missing alt" is a ticket. "The alt text on this product photo describes a different product" is a finding a client understands at a glance. And a broken nav component doesn't read as a separate error on every page: each problem is listed once, with how many times it occurs and examples of where, so your developer sees one component to fix instead of the same error repeated across pages.
When a client asks what was checked and when, you can show them. Every issue keeps its history in your dashboard: first seen, last confirmed and the recent checks on that page. Export the issue list as a CSV file or print a report for the client. We issue no badge and never claim anyone is "compliant"; we record what was checked and when.
Free for checking your own work as you go. Paid for when you want your pages watched every week: you hear about a break at the next check, and you keep a dated record of what was checked and when. Plans are priced by the number of pages you monitor.

Every week, on the pages you choose, GotAlt opens up to six images per page and checks that each alt text is true of its picture, and you hear when something breaks. The plans carry a full refund within 7 days of your first payment, and you can cancel from your account page at any time. The Site Image Check has its own refund line, on its card above. Full pricing and what's in each plan.
No, and be wary of any tool that says otherwise. Automated checks cover a meaningful part of WCAG (the technical standard behind the EAA, ADA cases, and Section 508), but full conformance also needs human review of things like contrast, keyboard flows, and content clarity. GotAlt finds the issues machines can find, tells you what's left, and helps you track progress.
WCAG is the technical standard these laws point to, among them the EU's European Accessibility Act (in force since June 2025), the US ADA and Section 508 and the UK Equality Act. The free scan runs 16 rule checks, 13 of them mapped to WCAG success criteria; it does not assess whether a site meets any law.
Broadly: if you sell to EU consumers online, it likely applies, wherever your company is based. There's one notable carve-out: microenterprises providing services (fewer than 10 employees and under €2M turnover) are exempt. Accessibility can still matter for you regardless: ADA exposure, customer reach, and SEO don't have a headcount exemption.
It shows you where a page is likely to stop making sense for someone who can't see it, and whether your image descriptions are true of the pictures. Two passes deliver that. The free scan fetches your page (plus up to two linked pages) and runs 16 rule-based WCAG checks on the HTML, the same class of checks other scanners run. The deep AI audit then downloads your actual images, up to six per page, and asks a vision model whether each alt text truly describes its image, and reads your link text and headings for clarity. We don't inject widgets or modify your site.
You find out when an image description is wrong, not only when it is missing, and a weekly re-check tells you when that changes. A rule-based scanner reads your HTML and applies rules: is there an alt attribute, a label, a heading. GotAlt runs those checks too, and the scan is free. What it adds is the deep audit: it opens your images (up to six per page) with a vision model and checks that each alt text is true of the picture, then re-checks your monitored pages every week and emails you when a check finds a new critical or serious issue. That check finds problems that pass every rule engine cleanly.
Free scan and audit results are returned to your browser and not kept on our side. If you sign up for paid monitoring, that's different by design: we store the pages you ask us to watch and their weekly check history, because tracking change over time is the point. Full detail is in our privacy policy.
If the scan finds images with no alt text, a draft description for each one is minutes away. Drop the images into our free AI generator and get WCAG-friendly alt text to review and edit. 3 free images a day, after a one-time email.
Scan up to three pages free, then see whether the alt text on your images is true of the pictures. To check more of your site, check up to 50 pages once, $49, no subscription.
