Vivian: PDF and document accessibility. Broken documents go in. Compliant documents come out.
Vivian remediates PDF libraries against WCAG 2.1 AA at scale: structure tags, reading order, alt text, forms, and the audit-ready report your counsel actually asks for. Automated where confidence is high. Human-reviewed where it is not.

Every other tool checks. Vivian fixes.
Remediating one PDF by hand takes two to four hours. A university sits on a hundred thousand of them. The pipeline runs the math the other way, and every stage leaves evidence.
01
parse
Structure, text, images, and form fields extracted with spatial geometry intact.
02
analyze
Headings, reading order, tables, links, and language inferred; every failure mapped to its WCAG criterion.
03
propose
Type-aware alt text (equations to LaTeX and MathML, charts by trend), each with an honest confidence score.
04
gate
At or above your threshold, fixes auto-apply. Below it, they queue for a human. Never silently.
05
remediate
A machine-verifiable tag tree written into the PDF: MCIDs, roles, alt text, reading order, real tables, repaired fonts.
06
report
An audit-ready report: issue inventory, remediation log, confidence disclosure, version history.
Confidence-gated, not blindly automated
Every AI decision carries a confidence score. At or above your threshold, the fix is applied and logged. Below it, a reviewer sees the proposal, the score, and the reason, then approves, edits, or rejects. Medical imaging and technical diagrams always go to a human, regardless of score.
The deadlines are federal law
The Department of Justice adopted WCAG 2.1 AA as the ADA Title II standard for state and local government content, including PDFs used to access services. HHS mirrors those dates for recipients of federal health funding. Preexisting documents lose their exception the moment someone needs them to apply for or access a service.
Dates reflect the 2026 interim final rules extending the original deadlines by one year; those extensions are under legal challenge, so treating earlier readiness as lower risk is prudent.
| Rule | Standard | Who | Compliance date |
|---|---|---|---|
| ADA Title II (28 CFR Part 35) | WCAG 2.1 AA | State and local government, population 50,000+ | April 26, 2027 |
| ADA Title II (28 CFR Part 35) | WCAG 2.1 AA | Smaller entities and special districts | April 26, 2028 |
| HHS Section 504 (45 CFR Part 84) | WCAG 2.1 AA | Recipients of HHS funding, 15+ employees | May 11, 2027 |
| Section 508 (36 CFR Part 1194) | WCAG 2.0 AA | Federal agencies | In force |
Automated analysis. Not legal certification.
Flagged items need your review; complex documents deserve accessibility specialists. Sophisticated buyers know the difference, and the honest boundary is exactly what makes the audit trail worth standing behind. It is printed on every report Vivian produces:
This report documents Vivian's automated analysis and remediation. It is not a legal certification of compliance. Organizations should review flagged items and consult accessibility specialists for complex documents.
