The real accessibility gap is in your documents.

Most ADA Title II risk sits in downloadable documents — forms, policies, reports, agendas, and public records. Untagged, out of reading order, or unreadable to screen readers. Alto fixes them at scale and gives you the evidence to show progress.

Fix Documents at Scale

Missing tags, headings, reading order, table structure, form fields, and alt text — remediated automatically. No trained accessibility staff needed.

Prove Compliance Per File

Every remediated document includes a veraPDF conformance report you can hand to legal, auditors, or ADA coordinators — clear evidence of accessibility work.

Built for Government & Education

Designed for state, county, and local governments, K-12 districts, and public colleges preparing for the April 2026 ADA Title II deadline. No accessibility expertise required.

How it Works

Audit it. Fix it. Prove it.

Step One

Find high-risk documents

We scan your PDFs against WCAG 2.1 Level AA and PDF/UA standards. You see every failure — missing tags, reading order issues, unlabeled tables — before we touch anything.

Step Two

Fix issues automatically

AI-powered remediation handles missing tags, headings, reading order, table structure, form fields, and alt text. Complex documents with scanned pages get OCR. No manual work required.

Step Three

Prove compliance per file

Every remediated document includes a veraPDF conformance report — clear evidence that the file has been tested and meets WCAG 2.1 Level AA and PDF/UA standards.

Deadline

ADA Title II compliance begins April 2026.

Title II of the Americans with Disabilities Act requires state and local government digital content — including public-facing PDFs — to meet WCAG 2.1 Level AA. Large entities must comply by April 24, 2026; small entities by April 26, 2027. Start remediating now — with proof.

Everything Behind the Download Button

Fix forms, reports, agendas, and public records — at scale.

Permit forms, board packets, meeting minutes, policy documents, HR forms, student handbooks — the files residents, businesses, and students actually download. Alto remediates them automatically, including scanned and image-only PDFs that need OCR.

Why Alto

How Alto Compares
to Other Options.

Manual in-house remediation is slow. Basic checker tools flag problems but don't fix them. Traditional vendors charge per page with weeks of turnaround. Alto remediates at scale with proof.
