How Remediate fixes a PDF

First we check your PDF, then we fix it. Here's what happens at each step, what Claude does, and what we can't fix for you.

No labels, so a screen reader gets one long stream of text.

The check

We check your file against the PDF/UA standard, using the version it says it follows or the one you pick. Every problem gets a short name, a count of where it happens, and the accessibility guideline it affects.

Checking is part of every plan and doesn't use any of your pages.

What the check tells you, by section of PDF/UA-1

7.20Embedded content can't be checked1.3.1
7.21Some fonts can't be read aloud1.3.1

The numbers are sections of PDF/UA-1, and each covers several checks.

The fix

Most fixes follow the standard to the letter. A few need judgment, like what an image shows, and Claude handles those. You don't need to answer anything.

FixFixes by the rules

Labels
Every part of the page says what it is

AIDone by Claude

Image descriptions
What each image shows, or that it can be skipped
Hidden text
Which hidden text is real, and which to skip
Pages with no labels
Where the headings are on a page with nothing marked
Title
A real title, not the file name
Language
So it's read in the right voice

You get the fixed PDF and a list of every change. The ones Claude made are marked AI.

What Claude sees

Only what it needs for each job, never your whole file. Claude is made by Anthropic.

  • To describe an image

    The image, cropped, and the text near it.

  • To sort hidden text

    Short snippets of the hidden text.

  • To find headings

    A picture of one page, with the paragraphs we found on it.

  • To set the title and language

    The opening text of the document.

If something can't be fixed

A few problems need the original file or a PDF editor, like fonts that were never included in the PDF. We fix everything else, then tell you what's left and how to fix it yourself.

Some fonts can't be read aloud (2 places)
