A polished AI-generated screen is not proof of an accessible or usable interface. A static mockup can help reviewers spot visible issues such as weak contrast, crowded text, unclear hierarchy, and small-looking controls. To assess keyboard access, semantics, focus, errors, responsive behavior, or whether people can complete a task, you need a working prototype—and usability testing with representative users.
Use WCAG 2.2 as the current reference for web accessibility, define exactly what you reviewed, and report findings within that scope. Treat prompts and AI critiques as aids to review, never as evidence that a design conforms.

What a mockup can—and cannot—tell you
WCAG 2.2 criteria are written as testable statements and are not tied to a particular technology. However, many criteria depend on implemented behavior or semantic structure that a screenshot does not expose. W3C advises using WCAG 2.2 to maximize the future applicability of accessibility work: WCAG 2.2.
| Review stage | What it can establish | What it cannot establish alone |
|---|---|---|
| Static mockup | Visible hierarchy, apparent contrast, text spacing, visible cues beyond color, and apparent control size. It can also reveal whether content specifications identify text alternatives for images. | Whether the coded page has correct semantics or labels, works with a keyboard or assistive technology, exposes visible focus, handles errors accessibly, adapts properly, or supports task completion. |
| Working prototype | Keyboard operation, focus order and visibility, labels and semantics, error handling, responsive states, and behavior across interactions. | Whether the experience is understandable and effective for its intended users without usability testing. |
| Usability testing | Whether people can complete representative tasks, including people with disabilities and assistive-technology users when they are included. | Conformance across product areas and states that were not tested or assessed. |
Keep these evidence types distinct in your notes and any published conformance statement. A visual inspection is useful, but it is not a WCAG conformance evaluation of a functioning product.
#1 Best Overall
- Replaceable in-line fuses protect both the meter and tester in the event a high current source on the vehicle is left on
- The multimeter is bypassed with the switch during connection in case of a power surge
- The tester and meter can remain connected until other computer systems shut down, isolating the drain
- As a convenience, stacking banana connectors are used on the tester
- This allows voltage to be measured on various locations on the vehicle during the drain test, using standard test leads
Define the scope before reviewing screens
Set boundaries before choosing examples. WCAG-EM 2.0 offers a repeatable process for evaluating web accessibility; its sampling and reporting guidance emphasizes a defined scope and conformance target. See WCAG-EM 2.0.
- Product boundary: Identify the site, app, or flow being assessed, including what is excluded.
- Conformance target: Name the WCAG version and level if you intend to make a conformance claim. Do not imply that a partial visual review establishes conformance.
- Technology and evidence: Record whether you reviewed images, design files, a prototype, or a deployed implementation, and what assistive technologies or browsers were used where relevant.
- Representative work: List the screens, content variants, and states in scope—such as default, error, empty, loading, and responsive states where they apply.
Choose a representative sample, not the prettiest screen
Generated interfaces can vary across prompts or runs, and an apparently simple screen may behave differently after interaction or adaptation. WCAG-EM 2.0 advises tailoring the sample to product scope; interaction, generated content, adaptation, and inconsistency can call for broader sampling. Review enough examples to expose meaningful variation rather than selecting only the strongest output.
- Include screens that represent the main tasks and distinct interaction patterns.
- Include materially different content, generated variants, and responsive or other adaptive states.
- Sample more broadly when outputs vary between sessions, components are inconsistent, or a flow contains many states.
- Record why each screen or state was selected so another reviewer can understand the coverage.
When comparing two mockups or tools, use the same tasks and a comparable range of screens and states. Otherwise, apparent differences may reflect sampling rather than design quality.

Inspect visible accessibility in the mockup
Static review should be explicit about what is visible and what remains unknown. For each sampled screen, inspect the following and capture the location and evidence for each finding.
- Information hierarchy: Is the primary task apparent? Are headings, grouping, and visual emphasis clear enough to guide the next action?
- Color and contrast: Does text and other meaningful visual information appear distinguishable from its background? Is color reinforced with text, shape, or another cue where meaning depends on it?
- Text spacing and readability: Is text crowded, clipped, or difficult to distinguish? A screenshot can expose a visual warning, but cannot prove how content responds to user-adjusted spacing.
- Apparent target size: Do controls look large and separated enough to find and activate? A rendered image alone cannot establish the actual interactive target bounds or behavior.
- Text alternatives in content requirements: If an image communicates information, check whether the content specification calls for an appropriate text alternative. A visual mockup cannot show whether that alternative is implemented correctly.
- Visible states: Look for representations of errors, selection, disabled states, and other states the task requires. Their appearance does not verify that the implementation exposes them correctly.
A 2025 study of static AI-generated interfaces assessed visual hierarchy, contrast, text spacing, and target size against selected WCAG 2.1 criteria. It used a 0–4 severity scale, from no issue to complete barrier; that scale describes the authors’ method, not a universal standard. The study also explains that measuring post-interaction accessibility and usability requires a functional interface. Read the 2025 static-UI study.
Test behavior in a working prototype
Once there is an interactive implementation, move from visual inference to direct testing. Exercise representative tasks, including the states that a static image cannot reveal.

- Use the keyboard: Navigate through the task without a pointer. Check that controls can be reached and operated and that the order makes sense.
- Track focus: Confirm that focus is visible and moves predictably as dialogs, menus, validation messages, and other interactive states appear.
- Check names and semantics: Inspect whether controls have understandable accessible names, roles, and states in the implementation—not merely visible labels in the design.
- Trigger errors: Submit incomplete or invalid information. Check whether errors identify the problem, are perceivable, and support recovery.
- Vary the viewport and content: Test responsive states and longer or otherwise varied content for clipping, overlap, lost controls, or changed interaction behavior.
- Complete the task: Ask users to perform representative tasks, and observe where they hesitate, make errors, or cannot proceed. Include people with disabilities and assistive-technology users where possible.
For a formal assessment, keep implementation testing and usability testing as separate but complementary evidence. A successful task by one participant does not establish WCAG conformance; a standards-based review does not, by itself, prove that the interface is usable for its audience.
Use consistent issue records and comparisons
Log findings individually rather than compressing them into an unexplained pass score. A useful record includes:
- Screen, state, and location of the issue.
- Relevant WCAG criterion when one can be identified, along with the guideline version and target level under review.
- Evidence: screenshot or design reference for visual findings; reproducible steps and observed behavior for prototype findings.
- Impact on the task and who may be affected.
- Severity definition and rating, with a documented method that other reviewers can apply.
- Whether the finding is observed, inferred from a static design, or still untested in implementation.
When comparing alternatives, assess task clarity, visible accessibility, interaction behavior, sample coverage and consistency, evidence quality, and the manual correction effort after generation. Do not treat faster generation as evidence of accessible quality. If you use a numeric score, explain how it was assigned and avoid presenting it as conformance unless a suitable, documented evaluation supports that claim.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Use AI prompts and critiques as review aids
It is reasonable to test accessibility-oriented prompt requirements as one variable in a design workflow. A 2025 Web Conference study compared five AI design tools using a baseline prompt and an accessibility-oriented prompt, focusing on criteria assessable in static images such as color use, contrast, text spacing, and target size. That study design supports trying explicit requirements; it does not establish that prompting makes outputs conformant or identify a universally best tool. Read the 2025 prompt study.
AI-generated critique can also suggest questions for a human reviewer. A 2024 preprint assessed 51 UI mockups, compared model suggestions with expert suggestions, and examined fit with practice with 12 expert designers. This makes model feedback a possible additional input—not a replacement for standards-based assessment or human validation. Read the 2024 mockup-feedback preprint.

Report the result without overstating it
A useful report lets a reader understand both the findings and their limits. Include the review date; WCAG version and target level, if applicable; product scope and exclusions; technologies and methods used; screens, content variants, and states sampled; findings with evidence and severity definitions; and known limitations, including what was not tested.
Be precise in the conclusion. For example, a report based only on screenshots can say that specified visible features were reviewed on the sampled screens. It should not claim that the product conforms to WCAG, works with a keyboard, or enables successful task completion unless those properties were assessed in an appropriate implementation and scope.
