Dashboard
This is AI Accessibility for TYPO3. The dashboard shows where your site stands: open issues, the site rating, images without alt text, and what needs your attention first.
AI alt text
Start with images. Queue a whole folder, and AI writes alt text drafts for every image in it. You review them, edit where needed, and approve them one by one or in bulk. Nothing goes live before you approve it. Generate a single image on demand, and mark purely decorative images as decorative. Coverage goes up as you go.
Scan and Fix Hub
Next, scan a page. You get a health score, issues sorted by impact and WCAG level, and a clear list of what to fix. Open an issue in Fix Hub: it explains the problem and how to fix it, with example markup. Set its status, filter by severity, and check colour contrast as you go. Automated checks find a lot, and a manual review still has its place.
Accessibility Widget
For your visitors, there is the Accessibility Widget. In the backend you choose the icon, its position and colour, the layout, the profiles on offer, and your own branding. On the live site, visitors open it and adjust the page to their needs, for example with a low-vision profile or more line height, and reset it with one click.
Content
In the editor, Live Audit checks content while you write. Type a sentence in capitals, and it asks whether that is really needed, so you can fix it before saving. You can also create a voiceover of a whole page, add the Voiceover plugin, and visitors listen to the page right on your website.
Plain language
For readers who need plain language, start the TYPO3 Localize wizard and choose Simplified text with AI Accessibility. The page is rewritten in simpler German, side by side with the original, and you decide when it goes live.
AI Agent
And you can simply ask. The AI Agent checks the current page and reports the score and the main issues. It suggests a fix with corrected markup, writes a German alt text that you can edit before you apply it, and summarises the page in plain language. Nothing changes until you approve it.

What is AI Accessibility for TYPO3?
AI Accessibility for TYPO3 is a premium TYPO3 accessibility extension from T3Planet that brings accessibility checks, a fix workflow and AI content tools into the TYPO3 backend. Editors scan pages, work through findings in Fix Hub and approve AI alt text, plain-language text and voiceovers. Visitors get a configurable accessibility widget. The Scanner, Fix Hub and the widget need no AI provider.
Free TYPO3 accessibility scanner for your page
Enter the URL of your TYPO3 page and get a WCAG score plus the automated checks it fails. The Scanner in AI Accessibility for TYPO3 runs this kind of check on your whole page tree, inside the backend.
Scan a TYPO3 page for WCAG issues
You get an accessibility score and the failed automated WCAG checks, with the number of affected elements and the WCAG success criterion for each.
Works for any public page and takes about 15 to 40 seconds. Pages behind a login and local addresses such as localhost or .ddev.site cannot be checked.
Run the Scanner for every page, on a schedule, inside TYPO3.

Find and fix accessibility issues in TYPO3
Scan pages from the page tree, work through findings as a team and keep checking after every release.
Accessibility Scanner and Dashboard: find issues before visitors do
Pick a page in the page tree and a depth: this page, one to three levels or the whole tree. The Scanner checks the HTML and merges all findings into one report.
- Summary cards for Critical, Serious, Moderate, Minor and Needs review, plus an Accessibility Health Score.
- WCAG A, AA, AAA and Best Practice breakdown, as recorded by the Scanner.
- The Dashboard shows open issues, alt-text drafts awaiting review and the recommended next step.
- No AI provider or API key needed. Each scanned page counts against your license page quota, never against AI Credits.
Fix Hub: turn findings into tracked work
Every Scanner finding becomes a card that editors and developers assign, fix, verify and close.
- Filter by severity, WCAG level, Best Practice or Needs review.
- Each card explains how to fix the issue and lists the affected elements with their HTML.
- Move cards from New to In Progress to Completed.
- Built-in contrast checker for WCAG 1.4.3 (AA) and 1.4.6 (AAA). Optional AI solution per finding.
Bulk Scans and Lighthouse: keep checking after launch
Queue pages once and let the TYPO3 Scheduler rescan them. Add Lighthouse scores for any public URL.
- Bulk Scans uses the Scanner engine and marks each page as Pending, OK or Error.
- Run the queue with the Scheduler task or
vendor/bin/typo3 nst3aa:monitor:run. - Lighthouse reports Performance, Accessibility, Best Practices and SEO for one URL. It needs a Google PageSpeed API key.
Live Audit in CKEditor: catch issues while you write
An Accessibility Check button in the rich text editor lists issues in the text and images you are editing, before you save.
- Real-time checks based on Editoria11y, for example an image without alt text.
- Uses no AI and no AI Credits. Switch it on once in AI Foundation under AI Features.
- For full-page checks across the page tree, use the Scanner.

Make content accessible with AI
Alt text, plain language and audio for editors, controls for visitors and a human review where automation stops.
AI alt text and image metadata: close the gaps in your media library
AI Accessibility for TYPO3 lists every image without alternative text per folder, drafts alt text, title and description with AI and publishes only what an editor approves.
- Status tiles show coverage, missing alt text, decorative images and drafts awaiting review.
- Generate per image, per selection or per folder, including translations. Large folders run on the Scheduler.
- Mark pure decoration as decorative, so screen readers skip it on purpose.
- Short or long alt text for PNG, JPEG, WEBP and non-animated GIF, optionally on upload.
Plain language and voiceovers: reach more readers and listeners
Turn existing pages into simpler text or audio without leaving TYPO3. Editors review every result before it goes live.
- Simplify Text rewrites page content into plainer language in the TYPO3 Localize wizard.
- AI Voiceover narrates a page or blog post. The AI Accessibility-Voiceover content element plays it (mp3, flac or wav).
- AI Audio turns a script or text file into a downloadable audio file.
- OpenAI voices work with AI Credits or your own key. ElevenLabs needs your own ElevenLabs key.

Not needed for T3AA: Scanner, Fix Hub, contrast checker and visitor widget work without any AI provider and without credits.
Optional for AI usage: AI Credits are a separate T3Planet service and not part of T3AA. They pay for AI usage, for example alt text, as an alternative to your own API key, which stays the default.

AI Accessibility for TYPO3 supports your work toward WCAG, BITV 2.0, EN 301 549 and the BFSG, which has applied since 28 June 2025. For the EU AI Act, people stay in control: every AI draft for alt text, simpler text or voiceovers waits for an editor's approval, and AI Foundation can label AI-generated content. A good score is a health indicator, not proof of conformance. A final human review stays essential, and AI Accessibility for TYPO3 is not a compliance guarantee.

Frequently asked questions about T3AA
T3AA – AI Accessibility for TYPO3 – is a premium TYPO3 extension from T3Planet (extension key ns_t3aa). It scans pages for accessibility issues, tracks fixes in Fix Hub, generates AI alt text, plain-language text and voiceovers, and adds a configurable accessibility widget for visitors.
No. T3AA is a premium extension with no free version, and it is not distributed through the TYPO3 Extension Repository (TER). You can test every feature in a 30-day free trial without a credit card, then buy an annual license per production domain.
T3AA 14.x supports TYPO3 12.4 LTS, 13.4 LTS and 14.x up to 14.4, with PHP 8.2 to 8.4. Older 1.x versions supported TYPO3 v11 to v13. To upgrade from version 1.5.2 or older, follow the reinstall guide in the documentation.
You need AI Foundation (ns_t3af 1.2 or higher, free in the TER), the T3Planet Shop extension (ns_license) with an active T3AA license and admin access to the TYPO3 backend. Install T3AA with composer require nitsan/ns-t3aa or through the T3Planet Shop, then apply the database changes.
No. The Scanner, Bulk Scans, Fix Hub, the contrast checker, Live Audit and the visitor widget run without an AI provider or API key. Only AI features such as alt text, simplified text, voiceovers and the Fix Hub AI solution need AI access through your own keys or AI Credits.
Only AI features in AI Credits mode: image metadata (one request for the alt text and one for title and description), Simplify Text, the Fix Hub AI solution and each voiceover or audio file. Scans, Bulk Scans, Lighthouse, Live Audit and the widget never use credits. Each request is metered by the amount of text or image data the model processes.
Each page that a scan processes counts against the page quota of your license, and one click can scan many pages depending on the depth. The quota is separate from AI Credits: scans never use credits, and AI features never reduce the quota.
Yes. Add pages to the Bulk Scans queue and create a T3AA Bulk Scans task in the TYPO3 Scheduler. Integrators can run the same queue with vendor/bin/typo3 nst3aa:monitor:run. Results appear in Fix Hub and on the Dashboard.
No. The Scanner and Lighthouse test only the machine-checkable part of WCAG, so a high score is a health indicator and not proof of conformance. Screen reader flow, keyboard use, navigation logic and form behavior need a person to review them. Use the Human Expert audit for a managed manual review.
The German Barrierefreiheitsstärkungsgesetz (BFSG) has applied since 28 June 2025. T3AA supports your work toward it, and toward WCAG, BITV 2.0 and EN 301 549, by automating repeatable checks and content tasks inside TYPO3. It is not a compliance guarantee, and a final human review remains essential.
Content stays in your TYPO3 instance. With your own API keys, requests go from your server straight to the provider you configure, with no T3Planet server in between. With optional AI Credits, requests are routed through T3Planet to the AI providers. Alt text is stored in sys_file_metadata and voiceovers in fileadmin. T3AA stores no visitor logs.
Yes. The frontend accessibility widget is part of the T3AA license, and there is nothing extra to buy. You enable it in AI Foundation under AI Features, then configure tools, profiles, layout, branding and the accessibility statement in the Accessibility Widgets tab of the module.
No. ElevenLabs works only with your own ElevenLabs API key and is not available in AI Credits mode. With AI Credits, voiceovers and audio use OpenAI text-to-speech. To use ElevenLabs voices, add your ElevenLabs account in AI Foundation as a provider.
No. Lighthouse uses the Google PageSpeed Insights API, which cannot reach localhost or .ddev.site addresses. Use a public staging URL for Lighthouse, or run the Scanner, which checks local HTML without a public URL.
