Tabnav alternative: a remediation service, or a tool

What Tabnav PDF remediation does well

• Does the work for you, including alt text, with a manual review pass
• Israeli, in Hebrew, IS 5568 and WCAG 2.2 AA named on its pages
• Website accessibility from the same vendor

Where it leaves you

• No per-page price published; the full service is priced by quote
• Right-to-left and visual-order Hebrew are not mentioned on its pages
• A finished file rather than the evidence behind each decision

Two different things for sale

Tabnav is an Israeli web-accessibility company whose PDF offering is a service: you hand documents over, a process combining automation with manual review and correction works on them, and accessible files come back. Its pricing page names AI among what is included.

Taggart is software you run. Checking is free and needs no account; the repair runs free on a free account, on your own file, up to 60 pages; a plan at $29 a month is for downloading the repaired file and its report.

Neither is the better product in general. They answer different questions: who does the work, and who is accountable for the judgement calls.

Everything said about Tabnav below is taken from its own pages as of September 2026 — its PDF remediation page, its PDF pricing page and its IS 5568 guide.

What Tabnav says it does

• Descriptions for images, diagrams and visual elements.
• Document structure: headings, paragraphs, lists, tables.
• Reading order, so a screen reader meets content in a logical sequence.
• Tables, forms, diagrams and other complex components.
• Contrast between text, backgrounds and visual elements.
• Compliance with IS 5568 and WCAG 2.2 AA.

Pricing is per page and set by a quote, with a free trial on a number of pages you choose. No per-page figure is published on the pricing page.

The differences that decide it

Who writes the alt text

A service writes it. Taggart does not: it puts each figure in a review queue with what the document already says about it — its caption, the words inside it, the lines around it — and you write the description or mark it decorative. For a report with 150 charts, that is hours of your time that a service would absorb.

If the decisive question is I do not have the hours, a service is the honest answer.

Hebrew stored in visual order

Many Hebrew and Arabic PDFs store their text pre-reversed. The page looks right; copied text, search and screen readers get it backwards. PDF/UA and the Matterhorn Protocol do not test for it, so a file can pass veraPDF, PAC and Acrobat’s checker and still read backwards. What that failure is →

Taggart detects it line by line, shows you the stored text beside the logical text and the evidence for each verdict, and repairs it without touching how the page looks. Tabnav’s pages do not mention right-to-left text or visual-order storage. That is a statement about what it says, not about what it can do — test it with a file that copies out reversed.

Knowing the price before you ask

Tabnav prices by quote. Taggart’s price is on its pricing page, and the check is free without an account. That is a difference in how each is bought as much as in what it costs: a quote suits a procurement process, a published price suits someone who wants to try it this afternoon.

What you can defend

Taggart’s report names each failure by its Matterhorn condition number, logs every human decision with who made it and when, and refuses to write a conformance claim while any condition needing a person is undecided. It does not produce a score. Whether that matters depends on who reads the report — an auditor, or a manager.

Where Tabnav is the better answer

• You have no one to do the judgement calls. Alt text, which lines are headings, whether a table’s first column labels its rows — a service decides these for you. Taggart asks you.
• You want one vendor for the website and the documents. Tabnav sells website accessibility too. Taggart does documents only.
• The document set is small and irregular. A handful of files a year does not justify learning a tool.

Where Taggart is

• Hebrew or Arabic PDFs that read backwards, which the standard checks do not catch.
• Volume. A monthly price with no per-page charge changes the arithmetic once you have hundreds of pages.
• You need to see the evidence, line by line and condition by condition, rather than receive a finished file.
• You want to try it now, on your own file, before talking to anyone.

Try them on the same file

Take one document that matters — ideally a Hebrew one that copies out reversed. Run it through Taggart’s free checker, which needs no account, and send the same file to Tabnav’s free trial. Compare what each finds and what each gives back. A document you actually publish will tell you more than either company’s page.
