Accessibility Sentinel
An R&D lab for digital accessibility. Your site could be audited for free.
Accessibility Sentinel builds automated detection methods for WCAG and RGAA compliance — automated scanners, real evidence (screen reader, session timeout, vision triage), independent evaluation of 162 criteria. To refine these methods on real cases, we're opening a limited number of complete, free audits: 100% of the features, in exchange for an anonymized case study and feedback.
Your site is the fuel for our lab
A research lab needs real cases to validate its methods — not mockups. Rather than billing for our first audits, we give them away in full, in exchange for use as a case study and honest feedback.
100% of the features
The same audit we'd otherwise charge for — no watered-down version: automated scanning, real evidence, 162 WCAG + RGAA criteria, full deliverables.
Two simple commitments
Authorize an anonymized case study and give us feedback — no payment requested.
A limited number of spots
Every application is reviewed; we favor real sites and a diversity of sectors and tech stacks.
On our reference project
An independent audit of a high-traffic transactional website — the figures below come from that real project, detailed in our case study.
What sets us apart from standard scanners
Accessibility Sentinel grew out of an R&D lab building automated detection methods for digital compliance — we're not a certification body, we surface concrete evidence and testable protocols your team can act on. Most audit tools stop where automation stops: they cover a fraction of WCAG/RGAA criteria, and the rest gets tagged "manual check required" and left there. We start from the opposite premise.
Real evidence instead of assumption
The speech a real screen reader (NVDA) actually says, an actual 30-minute wait to test a session timeout, a real simulated touch gesture — not heuristics approximating user behavior.
Every "manual" criterion stays actionable
For every criterion that can't be automated, a precise test protocol (tool, actions, pass/fail criterion) instead of a plain tag — a human auditor can pick up the work without starting from scratch.
WCAG and RGAA, two standalone frameworks
56 WCAG 2.1/2.2 A/AA criteria and 106 RGAA 4.1.2 criteria tested each on its own terms — a simple mapping table produces both false positives and false negatives.
Honest about the limits
Semantic judgments, screen-reader parity, real authentication: we document what remains fundamentally manual instead of hiding it.
Capability catalog
Large-scale automated detection, real evidence, scaling to a whole site, and deliverables ready for your teams.
Automated detection
axe-core 4.9.1 scanning in a real browser, DOM inspection (accessible names, heading structure, ARIA roles), automated keyboard navigation, contrast, 200% zoom, text spacing, office documents.
Real evidence
A bridge to NVDA with exact quotes of the speech heard, a real session-timeout test, vision-model-assisted triage for unlabeled icons, touch-gesture simulation.
Scaling to a whole site
Multi-agent orchestration to audit hundreds of pages in cascade, aggregating systemic defects (shared component rather than isolated symptom), explicit scoping.
Deliverables ready to use, in French and English
Structured CSV & Excel workbook
One finding per row, normalized columns (severity, WCAG criterion, RGAA criterion, detection method). Multi-tab workbook with native formulas, not hardcoded values.
Word report & interactive chat
Executive summary, detailed findings, annotated screenshots at exact DOM coordinates. Chat interface to query results in natural language, citing finding IDs.
Every deliverable ships as two separate files — French and English — not a single mixed-language document.
