We test your website the way blind users actually experience it. Real VoiceOver and NVDA navigation, not automated code scanning. Get results in 24 to 72 hours.

The Problem
A scanner might flag that a button lacks a label. But it cannot show you a blind user getting trapped in a cookie modal, unable to dismiss it. It cannot prove your checkout actually works. Courts and regulators want evidence of functionality, not just code violations.
How It Works
Our system navigates your website exactly like a blind user would, using real screen reader software to verify accessibility.
Our system uses actual VoiceOver and NVDA screen readers to navigate your site. No DOM simulation or code analysis. We experience your site the way real users do.
We prove that critical flows actually work: checkouts, logins, forms, and multi-step processes. These are the issues static scanners cannot test.
Human accessibility specialists review all findings. Every report includes actionable fixes with code examples and priority rankings.
The Technology
Our testing system is not a code scanner with AI marketing. It is a purpose-built artificial intelligence designed from the ground up to navigate websites exactly as a blind person would, using real screen reader software.

Compare Approaches
Static scanners are fast but shallow. Manual audits are thorough but slow and expensive. Sentium delivers the best of both.
This table compares three accessibility testing approaches. May require horizontal scrolling on smaller screens.
| Capability | Static Scanners | Manual Audits | Sentium |
|---|---|---|---|
| Testing Method | Scans code patterns | Human testers navigate site | AI uses real screen readers |
| Screen Reader Testing | Estimated from code | Manual, varies by tester | Real VoiceOver and NVDA, every test |
| Transaction Flows | Cannot test | Tested but time-intensive | Automated end-to-end verification |
| WCAG Coverage | 30 to 40% of criteria | Depends on auditor expertise | Functional criteria focus |
| Consistency | Same every run | Varies by tester and day | Same every run |
| Delivery Time | Instant | 2 to 4 weeks | 24 to 72 hours |
| Cost | Low (often free) | $10,000+ per audit | Starting at $2,500 |
| Evidence Format | Code snippets and rule IDs | Written reports | Video of screen reader experience |
Questions
Automated scanners like Axe, WAVE, or Lighthouse analyze code patterns and can catch about 30 to 40% of accessibility issues. Our system actually uses the website with real screen readers (VoiceOver and NVDA), just like a blind user would. This lets us verify that checkout flows, forms, and navigation actually work in practice.
Standard delivery is 72 hours. For urgent situations like lawsuit response, we offer 24-hour rush delivery for an additional fee. VPAT generation typically takes 72 hours for web applications.
You receive a detailed report with specific issues found, WCAG criteria mapping, severity rankings, and actionable fix recommendations with code examples. Defense audits include video evidence of screen reader testing. VPAT deliverables follow the ITI VPAT 2.4 format accepted by federal procurement.
Yes. Our Defense Audit reports are specifically designed for litigation support. They include video evidence of screen reader testing, timestamped findings, and can validate or refute specific plaintiff claims. Expert witness support is available if needed.
Our VPATs follow the ITI VPAT 2.4 format and include WCAG 2.1 Level AA conformance testing with detailed remarks for each criterion. This is the format accepted by US federal procurement and most enterprise procurement processes.
Yes. After an initial audit, we can set up ongoing monitoring to catch regressions as your site evolves. This is especially valuable for development teams shipping frequent updates. Contact us for custom monitoring packages.
