What is Accessibility Checker?
Accessibility Checker is a comprehensive AI-powered text analysis tool that evaluates written content against WCAG (Web Content Accessibility Guidelines) standards and broader accessibility best practices to ensure your text is usable by people with diverse cognitive abilities, learning disabilities, visual impairments relying on screen readers, and varying literacy levels. The tool examines reading grade level, sentence complexity, vocabulary difficulty, heading structure, content organization, use of acronyms and abbreviations, inclusive language, alt text requirements, link text quality, and content warning needs. It produces an accessibility compliance score with specific, actionable recommendations for bringing your content into alignment with accessibility standards that increasingly carry legal force under the ADA, Section 508, and international equivalents.
Text accessibility extends far beyond making content compatible with screen readers — though that's an important component. Truly accessible text must also be cognitively accessible, meaning people with dyslexia, ADHD, autism spectrum conditions, intellectual disabilities, low literacy, and age-related cognitive changes can all comprehend and use the content effectively. This tool addresses the full spectrum of text accessibility challenges that organizations face. It checks whether your content structure supports scanning and navigation, whether your language complexity matches your audience's capabilities, whether your formatting supports assistive technologies, and whether your word choices exclude or include people with disabilities. As legal requirements around digital accessibility expand globally and organizations face increasing litigation over inaccessible content, this tool provides the systematic evaluation needed to identify and fix accessibility barriers before they become legal liabilities or exclude members of your audience.
How Accessibility Checker Works
Input your text and the AI runs it through a multi-dimensional accessibility evaluation framework that mirrors the methodology used by professional accessibility auditors. The reading level analysis calculates complexity scores using multiple formulas calibrated specifically for accessibility contexts, where the target threshold is typically a 6th to 8th grade reading level for public-facing content. The structural analysis evaluates heading hierarchy, paragraph length, list usage, and content organization patterns that affect how easily users can navigate and scan the text. The language clarity module identifies ambiguous pronouns, double negatives, complex sentence structures, undefined jargon, and abstract concepts that create comprehension barriers for users with cognitive disabilities.
The results present an overall accessibility score on a 100-point scale with individual scores for each dimension — reading level, language clarity, structural organization, inclusive language, and assistive technology compatibility. Each finding includes a WCAG success criterion reference linking it to specific accessibility standards, a severity rating from minor to critical, and a concrete fix recommendation. The inclusive language audit flags ableist terminology, disability euphemisms, and language that frames disability negatively, providing person-first and identity-first alternatives appropriate to current community preferences. The tool checks that acronyms are defined on first use, that link text is descriptive rather than generic phrases like 'click here,' and that content warnings are present where topics might cause distress. A prioritized fix list orders recommendations by impact, helping you address the most critical accessibility barriers first when working under time constraints.
Benefits of Accessibility Checker
- Evaluate text accessibility across multiple WCAG dimensions simultaneously rather than checking reading level, structure, and inclusive language in separate disconnected tools
- Reduce legal risk from accessibility lawsuits that have increased dramatically as courts extend ADA requirements to digital content and organizational communications
- Ensure content reaches the estimated one billion people worldwide with disabilities by removing text barriers that currently exclude them from accessing your information
- Receive WCAG success criterion references for every finding so you can demonstrate compliance in accessibility audits and legal proceedings with specific standard citations
- Improve content quality for all users since accessibility improvements like clearer language, better structure, and descriptive links benefit every reader universally
- Prioritize fixes by impact severity so your team can address the most critical accessibility barriers first when resources and timelines are limited
- Build organizational accessibility competence by learning from detailed explanations of why each issue matters and how it affects users with specific disabilities
Tips for Best Results
- Target a 6th to 8th grade reading level for general public content since this threshold ensures comprehension across the widest range of cognitive abilities and literacy levels
- Check heading structure carefully because screen reader users navigate primarily by headings, and skipped heading levels break their ability to understand content hierarchy
- Replace every instance of generic link text like 'click here' or 'read more' with descriptive text that tells users where the link goes without surrounding context
- Define all acronyms and abbreviations on first use because screen readers may read them as words rather than letters, and many readers won't know their meaning
- Use the inclusive language audit results as a team training opportunity to build awareness of ableist language patterns embedded in common workplace vocabulary
- Check content warning recommendations seriously because unexpected exposure to distressing topics can cause real psychological harm to readers with trauma histories
- Run the checker on template content and reusable components first since fixing accessibility in templates automatically improves every page that uses them
Popular Use Cases
- Web content teams ensuring all published pages meet WCAG 2.1 AA compliance standards required by organizational policy, government contracts, or legal settlement agreements
- Educational institutions making course materials, syllabi, and learning platforms accessible to students with documented disabilities under legal accommodation requirements
- Government agencies complying with Section 508 requirements that mandate all public-facing communications and digital content meet federal accessibility standards
- Healthcare providers ensuring patient-facing materials about conditions, treatments, and medications are comprehensible to patients with varying cognitive abilities and literacy
- E-commerce companies checking product descriptions, checkout flows, and customer communications for accessibility barriers that exclude shoppers with disabilities from purchasing
- Human resources departments auditing job postings, benefits documentation, and employee communications to ensure equitable information access across the entire workforce
- Nonprofit organizations ensuring their advocacy materials and service information reach all community members including those with disabilities who most need their services
