Transparency Charter

We won't lie to you about accessibility

The FTC has fined accessibility overlay vendors for making false compliance claims to customers. We built Angstroma to be radically transparent about what automation can and cannot do.

WCAG 2.2 Coverage — What We Can Actually Do

Automated detection65%

axe-core identifies these issues automatically

AI-assisted (needs human review)20%

AI generates a suggested fix — a human reviewer must approve it before applying

Human expert required15%

Cognitive load, context, and judgment issues — no tool can automate these

Coverage percentages refer to WCAG 2.2 success criteria, not issues on any specific site. Automated detection figure based on published industry research into automated and guided-test coverage. Per-site coverage varies. A clean automated scan does not constitute ADA or WCAG compliance.

No vanity scores

Real WCAG violations — not marketing-friendly compliance percentages.

AI fixes labelled clearly

Every AI fix is marked and requires your approval before applying.

Widget ≠ compliance

The widget improves UX preferences. Compliance requires fixing source code.
