Free InDesign plugin · PDF/UA-1 · WCAG
TagAlly Check runs the same fifteen checks as TagAlly Pro and shows you exactly what stands between your InDesign document and an accessible PDF — each finding with the reason, the standard behind it, and a click that jumps straight to the spot in your layout.
No Java, no veraPDF, no helper program. It installs in seconds and runs entirely on your own machine.
Nothing is held back from the checking side. TagAlly Check is not a teaser version with three of the fifteen checks — it is the complete inspection, and it reports the same findings the paid version reports.
A list of error codes helps nobody. Every finding names the page and the object, cites the Matterhorn checkpoint or WCAG criterion behind it, and offers a button that selects the spot in your layout so you can look at it.
Two visual overlays make the invisible visible: one colours every graphic by whether it has an alternative text, the other draws the reading order as numbered badges across your pages. Both are free, and both are the fastest way to understand what a screen reader will do with your document.
The maturity bar tells you how far along you are. It is the honest answer to the question every deadline produces: is this document nearly done, or nowhere near?
Take the findings with you: copy them as a structured work list, or save them as an HTML file next to your InDesign document — print it from the browser and you have something to hand to a colleague or a client. It is a work list, not a certificate; that is what TagAlly Pro produces after the export.
And when a check cannot decide, it says so instead of guessing. The contrast check is the only one that calculates a value — colours are approximated from CMYK, and which surface lies beneath the text is derived from the stacking order of your objects. Where an image, a gradient or a transparency makes that impossible, TagAlly asks you to look rather than inventing a number, and a spot you have checked can be released with one click. Those findings carry their own label, “Review”, so they never look like an error you must fix.
The line is simple and we would rather state it plainly than let you discover it after installing: TagAlly Check diagnoses, TagAlly Pro treats. Everything that merely looks at your document is free. Everything that changes it, exports it, or proves it is the paid product.
Free, and complete on the checking side

If you fix your findings by hand in InDesign, TagAlly Check is all you need and it stays free. If you would rather not — and if you need a document that proves it passes — that is what TagAlly Pro is for. You can try it free for 30 days.
Since 2026 the European Accessibility Act does not ask for good intentions, it asks for evidence. TagAlly Pro exports your PDF, repairs what InDesign leaves out, validates the result against PDF/UA-1 with veraPDF and writes a conformance report: machine verdict, every failed rule in plain language, plus the checklist of the points no machine can judge, ready to sign.
That report is what you hand to a client or an authority. It is also the reason TagAlly Pro exists, and it is the one part of the workflow the free version deliberately does not do.
Adobe InDesign 2025 or newer, on macOS or Windows. That is the whole list. TagAlly Check needs no Java, no veraPDF and no helper program, because it never leaves the InDesign document — and it asks for no network access at all, which you can verify in the plugin manifest before you install it.
Your documents stay where they are. TagAlly Check reads your open InDesign document and writes nothing anywhere except the document title and language, and only when you ask it to.
