Your accessibility deadline is April 26, 2027.
California public agencies must make every website, app, PDF, and published document WCAG 2.1 Level AA compliant. Smaller entities (under 50,000 population) have 12 more months than the original April 2026 cutoff. Smart agencies are using them.
Watch the scanner work.
Drop a PDF on the left. Findings populate on the right in real time — mapped to WCAG 2.1 Level AA success criteria with severity, page reference, and remediation guidance.
Every WCAG 2.1 success criterion. Mapped, scored, exportable.
We test against all 50 Level A and AA success criteria across the four POUR principles. Findings are tagged with the exact criterion so your VPAT writes itself.
Set the bar your policy requires.
Some criteria — contrast, reading order, language of parts — Adobe Acrobat itself flags as requiring human verification. Your compliance team decides whether they should fail the document, warn, or stay advisory. SentraCheck lets you redefine severity per WCAG criterion or per individual rule, scoped to your company.
Per-criterion default
Pick a baseline severity for every finding under WCAG 1.4.3, 1.3.2, or any other criterion. Affects all rules that map to it.
Per-rule override
Need finer control? Override an individual rule like ADA-LOW-CONTRAST while leaving the rest of the criterion at default. Per-rule wins over criterion default.
Audit trail
Every override stores who changed it and when. The full history is visible inline on the criterion page so your compliance team has a defensible record.
Future scans only
Overrides apply to the next scan onward. Historical scan records stay frozen — no compliance status flips retroactively, no audit headaches.
From inaccessible PDF to WCAG 2.1 AA HTML — in one step.
Most agencies publish PDFs that are unreadable to screen readers. We rebuild the document as semantic HTML — headings, lists, tables, and alt text intact. Drag the slider to compare.

Don't just find the issues. Fix them.
Upload a PDF and SentraCheck repairs the most common accessibility failures automatically — then hands it back ready to download. For every image, Claude vision suggests alt text; you review and approve.
Drag & drop any PDF. It's processed transiently and never stored — no document record, no retention.
We auto-fix what we can and pre-fill AI alt text for each image. Edit any suggestion, or mark an image decorative.
Download a repaired PDF, ready to publish — usually in seconds. Re-scan to confirm the score jump.
Sets a descriptive title so the document is identifiable. WCAG 2.4.2.
Turns on DisplayDocTitle so readers show the title, not the filename. PDF/UA.
Sets the language so screen readers use correct pronunciation. WCAG 3.1.1.
Sets structure tab order on every page so AT navigates logically. WCAG 2.4.3.
Generates a navigable outline from the document's headings. WCAG 2.4.5.
Adds accessible names to unlabeled form fields. WCAG 1.3.1 & 4.1.2.
Describes bare URL links so their purpose is announced. WCAG 2.4.4.
Claude vision drafts alt text for every image — you review, edit, or skip. WCAG 1.1.1.
Independently validated. Every remediated document is checked against ISO 14289-1 (PDF/UA-1) with veraPDF — the PDF Association's open-source conformance validator — and the verified result is shown on each scan. Automated validation covers the machine-checkable requirements; a human should still confirm alt-text quality and reading order.
Honest about the limits. Structural tagging, reading-order rewrites, and complex data tables still need a human — SentraCheck flags those clearly so nothing slips through. For deep structural fixes, convert the PDF to fully tagged WCAG 2.1 AA HTML in one step (above).
Find every accessibility issue in your entire document corpus.
Send us your published PDF library — we count every page, score it against WCAG 2.1 AA, and return a remediation plan in 5 business days. Sized to your April 2027 deadline.
