FormsIQ: Make PDF forms accessible faster.

FormsIQ helps accessibility professionals remediate PDF forms with speed, accuracy, and confidence. Go from untagged fields to an organized tags tree in minutes, not hours.

  • Automatic Annotation Detection finds untagged form fields and adds them to the tag structure.
  • Order Detection Algorithm places each field and its label in order. You verify, or adjust if needed.
  • Faster Tooltip Creation applies verbs like Enter, Select, and Choose to tooltips globally.
  • Two Ways to Work lets you switch between synchronized PDF and table views.

FormsIQ Key features

Every field matched to its label

On the page, each field and its label share a colour, and a badge shows how sure FormsIQ is of the match. The list beside the page shows what is matched, what needs review and what is unmatched.

Screenshot of the Forms IQ interface showing the color-coded matching system that allows a user to quickly see the fields have been matched to the appropriate label.
Chax Registration Form.pdf: 18 fields matched, 1 to review, none unmatched.

Broken tags found and rebuilt

When the original file tags two fields as one, FormsIQ rebuilds the tag and flags the field, so you check that match before anything else.

Screenshot of Forms IQ showing a detected error and the fix. The error reads: "Signature: its tag was broken in the original file. It shared one tag with Facts. Forms IQ rebuilt it. Please check it is matched to the right label."
The Signature field shared a tag with Fax; FormsIQ rebuilt it and asks for a check.

The whole form in one grid

Grid View lists every field with its label, position, confidence and tooltip, with filters by status and page, a search, and a Done column to tick off as you go.

Tooltips for many fields at once

Tick several fields and set, prepend or append a phrase, find and replace, number them or change their case in one step, or fill them from their labels.

MathIQ: Immersive, accessible math in a PDF.

MathIQ embeds MathML into your PDFs so students can explore every part of an equation, without you needing a PhD in document accessibility.

  • Robust: students navigate equations at a granular level, not as one long description.
  • Empowering: the experience is in the students’ hands, so they explore math at their own pace.
  • Compatible: MathML for immersion, with alt text as a fallback.

MathIQ Key features

Check a formula at a glance

The formula as it appears in the PDF sits above the same formula drawn from its MathML. If the two pictures match, the MathML is right.

MathIQ interface showing the three main areas: the visual from the PDF itself, the MathML code view, and the rendering of the MathML as a preview where a user can compare the generated MathML to the visual element in the original document.
The quadratic formula from the page, its MathML preview and its MathML code.

Every formula, written in one run

Generate MathML for one formula, a ticked set, or every formula still missing it. The table shows each formula’s alt text, its MathML and where it came from.

Choose how equations are spoken

ClearSpeak reads mathematics the way a person would say it. MathSpeak, at three levels of detail, makes clear where each fraction or exponent begins and ends. Switch afterwards in one step; alt text you typed yourself is left alone.

Open straight from your Toolkit

A PDF opened from the Toolkit arrives ready to import. Choose whether MathIQ writes every formula while importing, and how formulas should be spoken.

TagsIQ: Turn untagged PDFs into usable documents.

TagsIQ tags your PDFs automatically, using proprietary logic to build a clean, organized tags tree. Start remediation from a clean structure instead of an auto-tag mess.

  • Clean Tag Structure builds a flat, organized tags tree, so you spend less time untangling auto-tag errors.
  • Untagged or poorly tagged? Start from almost any PDF and make it significantly more usable.
  • Finish-Line Ready lets you spend your time on the finishing touches toward PDF/UA and WCAG, not the cleanup.

TagsIQ Key features

A queue that shows its work

Add PDFs and TagsIQ works through them. The queue updates by itself and shows each step as it happens.

Screenshot of the initial upload of TagsIQ, showing the process of performing a quick scan: how many pages, pictures, and headings; how long it took; the language detected; and other process information
Chax Capabilities.pdf tagging: the quick scan found 5 pages, 19 pictures and 3 headings.

PDF/UA validation, before and after

The Validation report runs the PDF/UA check on the file before and after tagging: how much tagging improved it, the rules it fixed, and anything still to fix.

Screenshot of the validation report showing a 90% improvement, with one non-compliant error remaining.

A confidence score for every tagging

The Confidence report scores the tagging out of 100, counts the structures it found, and shows each point taken off and why.

A score of 92 out of 100 for the 5-page capabilities brochure.

ImageIQ: Alt text for every figure, minus the busywork.

ImageIQ generates alt text for the figures in tagged PDFs and filters out redundant descriptions, so screen reader users hear what matters.

  • Automatic Alt Text writes a description for each figure in a tagged PDF.
  • Redundancy Filtering keeps repeat descriptions out of the reading experience.
  • Built for Review lets you approve or edit every description before it goes into your file.
  • Pairs with TagsIQ: tag first with TagsIQ, then add alt text with ImageIQ.

Key features

Descriptions written for this document

ImageIQ shows what it read the document to be, then writes for that reader. A chart is described by the data that matters most, not just as “a bar chart”.

Check each description against the picture

Each figure is shown beside its new alt text and the alt text it had before, so you can compare them, edit, or undo a change.
