How to review a document’s accessibility with AI
To review document accessibility with AI, use the tool to organize questions and proposals, then check the actual file structure. Reading text pasted into a chat does not reveal every property of the distributed version.
The example is a team onboarding guide containing headings, a table and explanatory images. The task is identifying barriers and documenting corrections without claiming an automatic answer certified the document.
Start with the format and reader’s task
Record whether the delivery will be a web page, an editable document or an exported file. Also note what someone needs to locate and perform while reading.
In an onboarding guide, someone may look for a support contact, understand a sequence and complete information. These tasks provide concrete points for checking navigation and understanding.
Keep a version from before the review and work in the source file whenever possible. Correcting only an exported copy may leave the problem ready to return in the next update.
Map the headings
List the main title, sections and subsections without the body. Their order should communicate the document’s organization to someone not reading every paragraph.
The W3C headings and structure guidance explains their role in organization and navigation. In your editor, check appropriate styles or markup rather than only increasing font size.
Review this onboarding guide structure.
Propose headings explaining each section's role.
Identify topic jumps and material that is difficult to locate.
Do not claim accessibility based only on this analysis.
Separate wording suggestions from properties I need
to check in the editor and final file.The answer can improve section names but does not prove those headings were applied in the file. Record that distinction in the review.
Check links, images and tables
Read links outside their sentences and check whether the destination remains understandable. Replace generic labels when they fail to explain the action or related material.
For every image, identify the information it adds. Use the image description guide to prepare an alternative consistent with context.
For tables, check whether header and data relationships can be understood in the final format. A table used only to position objects needs different analysis from an information table.
| Element | Check in the file |
|---|---|
| Headings | Applied structure and understandable order |
| Links | Meaningful destination and label |
| Images | Alternative appropriate to their role |
| Tables | Identifiable headers and relationships |
| Reading | Sequence preserved in the delivery |
Examine presentation without losing structure
Check contrast, reading size and color use in the distribution version. Important information should not depend only on a color difference some readers cannot perceive.
The W3C writing tips support clear instructions. They do not replace checking the file in its editor, viewer and access tools relevant to your audience.
Review again after export
Open the final delivery and repeat real tasks: locate a section, follow a link and understand the table. If the format changes, do not assume every property survived conversion.
When necessary, involve people experienced in assessment and users of the material. The W3C preliminary checks introduction makes clear that initial checks are not a complete assessment.
Common mistakes and review results
Avoid treating visually organized text as verified structure, accepting invented descriptions and correcting the file without checking its export. Also avoid using “AI-approved” as evidence of content access.
Record the viewer and export settings used for that check. Finish with a list of discovered barriers, corrections made and aspects not yet assessed. The useful result is an improved document and an honest record of what was checked.
Frequently asked questions
Can AI certify a document’s accessibility?
A text or image analysis does not demonstrate access to every file property. Use suggestions as support and check the delivery with methods appropriate to its format.
Is a large heading necessarily semantic?
No. Appearance and structure differ. Check that the editor and final file identify headings appropriately.
What should I review after exporting a document?
Check the distributed version, including reading order, headings, links, tables and image alternatives according to its format and purpose.
