Rich Text Editor Accessibility Guide 2026: WCAG 2.1 AA Compliance Tested

Rich Text Editor Accessibility Guide 2026: WCAG 2.1 AA Compliance Tested

Accessibility used to be optional. In 2026, it's the law.

The rules changed fast in 2025 and 2026. If your product has EU customers, government contracts, or Fortune 500 buyers, your editor now needs to pass WCAG 2.1 AA. Miss it, and you're looking at lawsuits, lost enterprise deals, or products pulled from EU shelves.

This guide tested 8 editors against WCAG 2.1 AA using real accessibility tools. Not marketing claims — actual test results. Here's what we found.

The 4 Regulations That Made Editor Accessibility Mandatory

Four major regulations pushed WCAG 2.1 AA from "nice to have" to "must have" in 2026:

All four regulations use WCAG 2.1 AA as the technical standard. One editor can help you comply with all four — if it's built right.

What Non-Compliance Actually Costs

The financial risk is bigger than most teams realize.

• Class-action lawsuits: $75,000 to $500,000 typical settlements
• Lost enterprise deals: Fortune 500 procurement rejects vendors without WCAG documentation
• EU market restrictions: Non-compliant products can be pulled from EU sale
• Federal contract rejections: Section 508 blocks bids at procurement stage
• Reputation damage: Accessibility failures make news in tech press

For any SaaS product touching regulated markets, editor accessibility became a hard business requirement in 2026 — not a checkbox item.

How We Tested (Real Methodology, Not Marketing)

Most editor comparison guides claim accessibility in one bullet point and move on. We tested each editor against WCAG 2.1 AA using industry-standard tools:

• 🛠 aXe DevTools — automated accessibility scanner
• 💡 Lighthouse — Google's accessibility audit
• 🌊 WAVE — WebAIM's browser extension
• ⌨️ Keyboard-only navigation — every feature tested without a mouse
• 🔊 Screen readers — NVDA, JAWS, VoiceOver, TalkBack
• 🎨 Contrast measurement — Colour Contrast Analyser
• 📱 Mobile reflow — 320px viewport testing

Every editor got the same test suite. Every result is measured, not claimed.

Why Editor Accessibility Matters More Than Ever in 2026

Six specific factors elevated editor accessibility from "checkbox item" to "critical evaluation criterion" in 2026.

1. European Accessibility Act (EAA) Enforcement Started

The EAA took effect June 28, 2025 across all 27 EU member states. Consumer-facing digital products (including SaaS applications sold to EU customers) must meet WCAG 2.1 AA compliance. Non-compliance risks include market access restriction (products removed from EU sale), regulatory fines (up to €500,000 depending on member state), and civil liability claims. For any SaaS product with meaningful EU revenue, editor accessibility became mandatory in 2025 with enforcement escalating through 2026.

2. ADA Title II Regulations Finalized

The U.S. Department of Justice finalized ADA Title II regulations in April 2024 requiring state and local government web content and mobile apps to meet WCAG 2.1 AA compliance. Deadlines: April 2026 for public entities with 50,000+ population, April 2027 for smaller entities. Any editor deployed in government portals, education platforms, or public services must meet WCAG 2.1 AA by these deadlines.

3. Section 508 Enforcement Increased

U.S. federal procurement (Section 508) enforcement of WCAG 2.1 AA has increased dramatically. Federal agencies now routinely reject procurement bids from non-compliant vendors. For SaaS products selling to federal government (or federal contractors), editor accessibility is a procurement gate.

4. Class-Action Litigation Increased

Digital accessibility lawsuits under ADA Title III (private businesses) reached ~4,000+ federal filings annually in 2024-2025. Typical settlement ranges $75,000-$500,000 for consumer-facing products. Editor accessibility is a common lawsuit trigger — inaccessible rich text editors on content-heavy consumer products create clear compliance gaps.

5. Global Regulatory Alignment

AODA (Ontario, 2025 deadline), DDA (Australia), Equality Act (UK), and dozens of other regional accessibility mandates now all reference WCAG 2.1 AA as the technical standard. Global SaaS products face compounding compliance requirements across markets.

6. Corporate Procurement Requirements

Enterprise procurement processes at Fortune 500 companies increasingly require WCAG 2.1 AA compliance certification as vendor selection criteria. Editors without documented compliance testing lose enterprise deals to compliant competitors.

For editor buyers in 2026, choosing an accessible editor became a business risk mitigation decision rather than a nice-to-have feature. Non-compliant editors create ongoing legal, regulatory, and revenue risk that compounds over time.

What WCAG 2.1 AA Compliance Actually Means for Editors

Before comparing editors, understanding what WCAG 2.1 AA requires clarifies what compliance actually looks like in practice. The standard breaks into four principles (Perceivable, Operable, Understandable, Robust) with 50 success criteria at AA level. For rich text editors specifically, twelve criteria matter most.

The 12 Editor-Critical WCAG 2.1 AA Criteria

1. Non-text Content (1.1.1, Level A)
Every image, icon, and non-text element in the editor toolbar must have accessible text alternatives. Icons alone aren't enough — screen readers need aria-label or hidden text.

2. Info and Relationships (1.3.1, Level A)
Semantic structure must be programmatically determinable. Headings must use <h1>-<h6> tags, not styled <div> elements. Lists must use <ul>/<ol>. Tables must have proper <th> header cells.

3. Contrast Minimum (1.4.3, Level AA)
Editor UI text and content text must meet 4.5:1 contrast ratio (3:1 for large text). Toolbar buttons, menu items, and content areas must all pass contrast testing.

4. Resize Text (1.4.4, Level AA)
Users must be able to resize text up to 200% without loss of functionality. Toolbars must remain usable at high zoom levels.

5. Keyboard (2.1.1, Level A)
All editor functionality must be operable via keyboard alone. No mouse-only interactions. Every button, dropdown, and command must have keyboard equivalents.

6. No Keyboard Trap (2.1.2, Level A)
Keyboard focus must not be trapped in modal dialogs, popovers, or nested widgets. Users must be able to escape to the rest of the page.

7. Focus Order (2.4.3, Level A)
Keyboard tab order must follow logical reading order. Toolbar buttons should be reachable in expected sequence, not random.

8. Focus Visible (2.4.7, Level AA)
Keyboard focus must have a visible indicator meeting contrast requirements. Focus rings must not be removed via CSS.

9. Name, Role, Value (4.1.2, Level A)
All UI components must have programmatically determined name, role, and current value. Custom widgets must use proper ARIA roles (toolbar, button, menu, menuitem).

10. Status Messages (4.1.3, Level AA)
Save confirmations, error messages, and state changes must be announced to screen readers via ARIA live regions.

11. Bypass Blocks (2.4.1, Level A)
Users must be able to skip repeated content. Editors embedded in pages should not force screen readers through repeated navigation.

12. Reflow (1.4.10, Level AA)
Content must reflow at 320px width without horizontal scrolling. Mobile editor UIs must adapt to narrow viewports.

Editors passing all 12 criteria meet WCAG 2.1 AA compliance. Editors failing any criterion create potential accessibility litigation risk and regulatory compliance gaps.

For deeper accessibility context, see the W3C Web Content Accessibility Guidelines (WCAG) 2.1 documentation and Deque's WCAG 2.1 AA compliance guide.

WCAG 2.1 AA Testing Methodology

Editor accessibility claims vary widely based on measurement methodology. Here's how these editors were tested for real 2026 compliance.

Testing Tools Used

Automated Testing:

• aXe DevTools 4.10+ — industry-standard automated accessibility scanner
• Lighthouse 12+ — Google's accessibility audit (Chrome DevTools)
• WAVE Web Accessibility Evaluation Tool — WebAIM's browser extension
• Pa11y — command-line accessibility testing

Manual Screen Reader Testing:

• NVDA 2024.4+ on Windows (most-used free screen reader)
• JAWS 2025 on Windows (enterprise standard)
• VoiceOver on macOS Sequoia + iOS 18 (Apple's built-in)
• TalkBack on Android 14+ (Google's built-in)

Manual Keyboard Testing:

• Tab navigation through entire editor UI
• Arrow key navigation within toolbars
• Escape key behavior in modals and popovers
• Enter and Space activation on all interactive elements
• Custom keyboard shortcuts documentation

Visual Testing:

• Contrast ratio measurement with Colour Contrast Analyser
• 200% text zoom testing
• 320px viewport reflow testing
• Focus indicator visibility across all UI elements

Testing Environment

• Browsers: Chrome 130+, Firefox 130+, Safari 18+, Edge 130+
• React version: React 19.0 with Next.js 15.1
• Test app: Vanilla Next.js starter with only the editor added
• User agents: Desktop mouse+keyboard, keyboard-only, screen reader, mobile touch

Pass/Fail Criteria

An editor "passes" WCAG 2.1 AA compliance testing when:

• 0 aXe DevTools violations at "moderate" or higher severity
• 0 Lighthouse accessibility issues at "serious" severity
• 0 WAVE errors (warnings acceptable if not violation-level)
• Full keyboard navigation across all documented features
• Screen reader announcements meaningful across NVDA, JAWS, VoiceOver
• All 12 editor-critical WCAG criteria pass manual verification

Editors failing any of these represent real accessibility risk requiring remediation before production deployment in regulated markets.

The 8 Best Rich Text Editors for WCAG 2.1 AA Compliance (2026 Test Results)

Here's how the 8 leading rich text editors compare on measured WCAG 2.1 AA compliance:

The pattern: Only three editors (CKEditor 5, Eddyter, TinyMCE with accessibility plugin) reliably ship production-ready WCAG 2.1 AA compliance without extensive custom engineering. Framework editors (Lexical, TipTap, Slate) require substantial accessibility engineering — the accessibility layer is your responsibility as the editor implementer. Quill's stalled development creates accessibility gaps that remain unaddressed.

1. CKEditor 5 — Best WCAG 2.1 AA Certified Editor

Compliance status: WCAG 2.1 AA certified via third-party audit | Keyboard navigation: Full | Screen reader support: NVDA, JAWS, VoiceOver tested | Custom config needed: Minimal

3. TinyMCE — Best Legacy Editor With Accessibility Plugin

Compliance status: WCAG 2.1 AA with accessibility plugin | Keyboard navigation: Full | Screen reader support: NVDA, JAWS, VoiceOver tested | Custom config needed: Accessibility plugin

TinyMCE reaches WCAG 2.1 AA compliance through its Accessibility Checker plugin (Premium tier) that provides real-time accessibility feedback during content creation. Best for teams with existing TinyMCE deployments needing compliance without full editor migration.

Where TinyMCE wins on accessibility:

• ✅ 22 years of accessibility development — deep experience with edge cases
• ✅ Accessibility Checker plugin provides content-level accessibility feedback
• ✅ Full keyboard navigation with configurable shortcuts
• ✅ Screen reader tested across major screen readers
• ✅ ARIA compliance in toolbar and dialog patterns
• ✅ Deep documentation on accessibility configuration

Where TinyMCE loses vs Eddyter:

• ❌ Accessibility plugin is Premium tier — additional cost on top of base subscription
• ❌ Heavy bundle (~500 KB) hurts Core Web Vitals on accessible pages
• ❌ Editor-load pricing ($40 per 1,000 additional loads) scales unpredictably
• ❌ AI Assistant separate paid add-on ($120/mo)
• ❌ Wrapper-based React integration creates accessibility edge cases with React 19

Real WCAG 2.1 AA test results (October 2025):

• aXe DevTools violations: 0 moderate or higher (with accessibility plugin)
• Lighthouse accessibility score: 95/100 (without plugin: 88/100)
• WAVE errors: 0 (with plugin)
• Manual keyboard testing: 100% features accessible via keyboard
• Screen reader announcements: Meaningful across NVDA, JAWS, VoiceOver

For migration paths, see TinyMCE Alternative and How to Migrate From TinyMCE to a Modern Editor 2026.

4. Lexical — Framework With Accessibility Baseline

Compliance status: Framework baseline (accessibility is your responsibility) | Keyboard navigation: Baseline handling | Screen reader support: Custom implementation required | Custom config needed: Substantial (2-4 weeks engineering)

Lexical provides accessibility primitives — semantic HTML output, focus management APIs, ARIA support in framework abstractions. But you build the toolbar, menu, and UI layer yourself, which means you're responsible for the accessibility of everything users interact with.

Where Lexical helps accessibility:

• ✅ Semantic HTML output built into node types
• ✅ Focus management APIs for custom UI implementations
• ✅ ARIA support in framework abstractions
• ✅ Meta-backed maintenance — accessibility patterns from Facebook Messenger/WhatsApp

Where Lexical requires custom accessibility work:

• ❌ Custom toolbar accessibility — ARIA roles, keyboard navigation, focus states all yours to implement
• ❌ Screen reader testing across NVDA/JAWS/VoiceOver for custom UI (~1 week testing)
• ❌ Focus indicator styling for custom themes
• ❌ Skip links and landmark structure for embedded contexts
• ❌ Custom widget accessibility — every custom plugin needs its own accessibility engineering

Building production-ready WCAG 2.1 AA on Lexical typically takes 2-4 weeks additional engineering beyond base editor functionality. Teams wanting Lexical's benefits without the accessibility engineering typically adopt Eddyter (built on Lexical with accessibility engineered in) instead.

For alternatives, see Best Lexical Alternative 2026 and How to Migrate From TipTap to Lexical 2026.

5. TipTap — Partial Accessibility With Custom Engineering Required

Compliance status: Partial (headless framework, accessibility is implementation-dependent) | Keyboard navigation: Baseline via ProseMirror | Screen reader support: Partial | Custom config needed: Substantial (2-4 weeks)

TipTap inherits accessibility baseline from ProseMirror (its foundation), but as a headless framework, you build the visible UI — and therefore the accessibility layer. Better than Lexical for accessibility since ProseMirror has more mature accessibility patterns, but still requires substantial custom engineering.

Where TipTap helps accessibility:

• ✅ ProseMirror foundation — battle-tested accessibility patterns
• ✅ Semantic content model — clean node types map to accessible HTML
• ✅ Community-maintained accessibility extensions

Where TipTap requires custom accessibility work:

• ❌ Custom toolbar UI — all ARIA roles, focus management, keyboard nav yours
• ❌ AI Toolkit ($500+/mo) accessibility not documented for compliance procurement
• ❌ Cloud pricing ($49-$999/mo) doesn't include accessibility certification

For deeper analysis, see TipTap Pricing Explained 2026 and Best TipTap Alternatives 2026.

6. BlockNote — Partial Accessibility With Known Gaps

Compliance status: Partial (React-native block editor with accessibility work in progress) | Keyboard navigation: Some gaps | Screen reader support: Partial | Custom config needed: Configuration + fixes

BlockNote's block-based Notion-style architecture creates specific accessibility challenges — block reordering via drag-drop needs keyboard alternatives, slash commands need screen reader announcements, block selection needs ARIA descriptions. Active accessibility development but production gaps remain.

Where BlockNote loses vs Eddyter:

• ❌ Drag-drop block reordering requires keyboard alternative implementation
• ❌ Slash commands need custom screen reader announcements
• ❌ Block boundaries don't always announce correctly to screen readers
• ❌ React-only (no Vue, Angular, Svelte for teams needing multi-framework accessibility)

For comparisons, see BlockNote vs TipTap 2026.

7. Slate — Framework Only, Accessibility Is Your Responsibility

Compliance status: Framework baseline (you build everything) | Keyboard navigation: Custom build | Screen reader support: Custom build | Custom config needed: Complete engineering (4-6 weeks)

Slate is a React-native framework for building rich text editors. Framework only — no UI, no toolbar, no accessibility layer. Building WCAG 2.1 AA compliant editor on Slate takes 4-6 weeks including accessibility testing across NVDA, JAWS, VoiceOver.

For teams building custom editor products where accessibility is a core requirement, Slate can work — but the accessibility engineering effort matches base editor implementation effort. For most teams, using accessible complete editors (CKEditor 5, Eddyter, TinyMCE) delivers better ROI.

For analysis, see Eddyter vs Slate 2026.

8. Quill — Known Accessibility Gaps, Not Recommended for Compliance

Compliance status: Known WCAG 2.1 AA gaps | Keyboard navigation: Partial | Screen reader support: Limited | Custom config needed: Substantial (development stalled)

Quill has documented accessibility gaps that remain unaddressed due to stalled development since 2022. Toolbar keyboard navigation incomplete, screen reader support limited, and community-maintained accessibility improvements haven't reached production quality.

Not recommended for teams requiring WCAG 2.1 AA compliance in 2026. For simple prototypes without compliance requirements, Quill's ~45 KB bundle remains competitive. For any production deployment in regulated markets, migrate to CKEditor 5, Eddyter, or TinyMCE.

For migration paths, see Quill Alternative 2026.

Real-World Accessibility Configuration Guide

Whatever editor you choose, additional configuration typically improves accessibility beyond editor defaults. Here's guidance for each layer.

1. Editor Toolbar Accessibility

Ensure toolbar buttons have accessible labels:

jsx

1
2
3
4
5
6
7
8
9
10
11
12
// Good: Explicit aria-label
<button
  onClick={handleBold}
  aria-label="Bold"
  aria-pressed={isBold}
>
  <BoldIcon aria-hidden="true" />
</button>
// Bad: Icon only, no accessible label
<button onClick={handleBold}>
  <BoldIcon />
</button>

Group related toolbar buttons with proper ARIA:

jsx

1
2
3
4
<div role="toolbar" aria-label="Text formatting">
  <button aria-label="Bold" aria-pressed={isBold}>B</button>
  <button aria-label="Italic" aria-pressed={isItalic}>I</button>
</div>

2. Focus Management in Modals

Ensure dialogs trap focus and restore on close:

function LinkDialog({ open, onClose, onSubmit }) {
  const firstFocusRef = useRef(null);
  const triggerRef = useRef(null);
  useEffect(() => {
    if (open) {
      triggerRef.current = document.activeElement;
      firstFocusRef.current?.focus();
    } else if (triggerRef.current) {
      triggerRef.current.focus();
    }
  }, [open]);
  if (!open) return null;
  return (
    <div
      role="dialog"
      aria-labelledby="link-dialog-title"
      aria-modal="true"
    >
      <h2 id="link-dialog-title">Insert Link</h2>
      <input
        ref={firstFocusRef}
        aria-label="Link URL"
        placeholder="https://..."
      />
      <button onClick={onSubmit}>Insert</button>
      <button onClick={onClose}>Cancel</button>
    </div>
  );
}

3. Live Regions for Status Updates

Announce save status to screen readers:

function EditorWithSaveStatus() {
  const [saveStatus, setSaveStatus] = useState('');
  return (
    <>
      <YourEditor onChange={handleChange} />
      <div
        role="status"
        aria-live="polite"
        aria-atomic="true"
        className="sr-only"
      >
        {saveStatus}
      </div>
    </>
  );
}

4. Keyboard Shortcuts Documentation

Provide keyboard shortcuts help modal accessible via ? key or menu:

jsx

function KeyboardShortcutsHelp() {
  return (
    <dialog aria-labelledby="shortcuts-title">
      <h2 id="shortcuts-title">Keyboard Shortcuts</h2>
      <dl>
        <dt><kbd>Ctrl+B</kbd> (or <kbd>Cmd+B</kbd> on Mac)</dt>
        <dd>Bold text</dd>
        <dt><kbd>Ctrl+I</kbd></dt>
        <dd>Italic text</dd>
        <dt><kbd>Ctrl+K</kbd></dt>
        <dd>Insert link</dd>
      </dl>
    </dialog>
  );
}

5. Reduced Motion Support

Respect user preferences for reduced motion:

css

1

3
4
5
6
7
8
@media (prefers-reduced-motion: reduce) {
  .editor-toolbar-transition {
    transition: none;
  }
  .editor-animation {
    animation: none;
  }
}

Common Accessibility Pitfalls (And How to Avoid Them)

Teams building accessible editor products consistently hit these issues.

Pitfall 1: Icon-Only Toolbar Buttons

Toolbar buttons with only icons and no accessible text fail WCAG 1.1.1 (Non-text Content). Every button needs aria-label or visible text label. Screen readers can't announce "the third button" — they need "Bold" or "Insert Link."

Pitfall 2: Custom Focus Styles That Remove Focus Rings

CSS outline: none on focus is a common pattern that fails WCAG 2.4.7 (Focus Visible). Always provide alternative focus indicators — custom borders, box-shadows, or background colors meeting contrast requirements.

Pitfall 3: Keyboard-Only Users Can't Escape Modals

Modals that trap keyboard focus without escape mechanisms fail WCAG 2.1.2 (No Keyboard Trap). Every modal must support Escape key to close and restore focus to trigger element.

Pitfall 4: Drag-Drop Without Keyboard Alternatives

Block-based editors with drag-drop reordering (BlockNote) fail WCAG 2.1.1 (Keyboard) unless alternative keyboard patterns provided. Arrow key shortcuts for reordering, or menu-based "Move up/down" commands.

Pitfall 5: Missing Live Region Announcements

Save confirmations, error messages, and AI generation status that appear silently fail WCAG 4.1.3 (Status Messages). Use ARIA live regions (aria-live="polite" for non-urgent, aria-live="assertive" for urgent).

Pitfall 6: Insufficient Color Contrast

Toolbar buttons, placeholder text, and disabled states frequently fail WCAG 1.4.3 (Contrast Minimum). Test with Colour Contrast Analyser or Chrome DevTools. Placeholder text needs 4.5:1 contrast even though it's grey by convention.

Pitfall 7: Custom Widgets Without ARIA Roles

Custom UI (slash commands, popovers, tooltips) without proper ARIA roles fail WCAG 4.1.2 (Name, Role, Value). Use role="menu" for menus, role="tooltip" for tooltips, role="dialog" for modals.

Frequently Asked Questions

1. Which rich text editor has the best WCAG 2.1 AA compliance in 2026?

For most teams, CKEditor 5 and Eddyter tie for best WCAG 2.1 AA compliance. CKEditor 5 has third-party accessibility audit documentation useful for enterprise procurement, but costs $144-$864/mo Cloud + AI plan. Eddyter ships WCAG 2.1 AA compliance out of the box at $12-$59/mo flat pricing with modern UX (AI features, 7-framework support, 10-minute setup) that CKEditor 5 lacks. For enterprise procurement requiring third-party audit documentation, CKEditor 5 wins. For most other WCAG 2.1 AA use cases, Eddyter delivers better value.

2. Does WCAG 2.1 AA compliance really matter for my rich text editor?

Yes, materially. The European Accessibility Act took effect June 2025 requiring WCAG 2.1 AA for consumer digital products in the EU. U.S. ADA Title II regulations require WCAG 2.1 AA for state/local government by 2026-2027. Section 508 procurement enforcement means federal contracts require WCAG 2.1 AA compliance. ADA Title III lawsuits over inaccessible editors typically settle at $75,000-$500,000. For any SaaS product with meaningful EU customers, government contracts, or enterprise procurement processes, editor accessibility became a business risk mitigation decision in 2026.

3. What's the minimum accessibility I need for my rich text editor?

At absolute minimum: (1) all toolbar buttons have accessible labels via aria-label, (2) full keyboard navigation without mouse dependencies, (3) visible focus indicators meeting 3:1 contrast, (4) semantic HTML output with proper heading levels, (5) escape key support in all modals, (6) live region announcements for save status. These six items cover the highest-frequency WCAG 2.1 AA compliance gaps in editor implementations. Full WCAG 2.1 AA compliance requires meeting all 12 editor-critical criteria listed above.

4. Can I add accessibility to a non-compliant editor after the fact?

Partially, but expensive. For framework editors (Lexical, TipTap, Slate), adding WCAG 2.1 AA compliance takes 2-4 weeks additional engineering including screen reader testing across NVDA, JAWS, and VoiceOver. For complete editors with accessibility gaps (Quill, older Froala versions), fixing gaps typically requires forking the editor or building custom UI on top. In most cases, migrating to an accessible editor (Eddyter, CKEditor 5, TinyMCE with accessibility plugin) delivers better ROI than retrofitting accessibility onto non-compliant editors.

5. How do I test my editor for WCAG 2.1 AA compliance?

Use a combination of automated and manual testing: (1) aXe DevTools browser extension for automated scanning, (2) Lighthouse accessibility audit in Chrome DevTools, (3) WAVE browser extension for visual accessibility indicators, (4) manual keyboard testing (unplug mouse, try all editor features), (5) manual screen reader testing with NVDA (free) or VoiceOver on Mac, (6) color contrast measurement with Colour Contrast Analyser, (7) 200% text zoom testing, (8) 320px viewport reflow testing. Full WCAG 2.1 AA testing typically takes 4-8 hours per editor implementation.

6. Are AI editor features WCAG 2.1 AA compliant?

Depends on implementation. AI features (chat, autocomplete, streaming output) need accessibility considerations: streaming output must not break screen reader announcements (use aria-live appropriately), AI chat interfaces need proper form labeling and keyboard operability, generated content must maintain semantic HTML structure. Eddyter's AI features (GPT-5, Claude Sonnet 5, Haiku 4.5, Gemini 3) ship with accessibility considerations built in. TipTap AI Toolkit and CKEditor 5 AI plans have less documented accessibility testing. For teams requiring compliance, verify AI feature accessibility before deployment.

7. Does mobile editor accessibility differ from desktop?

Yes, additional requirements apply. Mobile editors need: (1) 44×44 pixel minimum touch targets (WCAG 2.5.5 AAA — not required but recommended), (2) reflow at 320px viewport width (WCAG 1.4.10 AA), (3) TalkBack (Android) and VoiceOver (iOS) screen reader compatibility, (4) mobile keyboard shortcut alternatives (many desktop shortcuts don't map to mobile), (5) landscape and portrait orientation support (WCAG 1.3.4 AA). Modern editors like Eddyter ship mobile accessibility built in. Legacy editors (older TinyMCE, older Froala) frequently have mobile accessibility gaps.

8. What accessibility documentation do enterprise procurement teams require?

Typically: (1) VPAT (Voluntary Product Accessibility Template) documenting WCAG 2.1 AA compliance status by criterion, (2) accessibility conformance report from third-party auditor, (3) accessibility statement on vendor website, (4) documented remediation process for accessibility issues, (5) accessibility roadmap for pending improvements. CKEditor 5 provides comprehensive procurement documentation. Eddyter provides conformance documentation on request through the sales process. Framework editors (Lexical, TipTap, Slate) don't provide procurement documentation because accessibility is implementation-dependent.
