No install, no licence file, no platform question. Open it, drop a PDF in, and you have the findings in about a second.
What the free validator does
- 75 of the 87 Matterhorn Protocol failure conditions software can decide; the other 12 are listed for you to confirm
- PDF/UA-1, WCAG 2.1 Level AA and IS 5568 profiles
- Right-to-left analysis: visual-order detection for Hebrew and Arabic
- Screen-reader preview — exactly what a reader announces, in order
- Structure tree with per-element geometry
- Several files at once, checked into one table
Unlimited. No watermark on anything and no expiry; no account needed up to 60 pages, and no page cap once you have a free one. Checking is commoditised — three good free tools already do it — so charging for it would only send you to one of them.
What a plan adds
- Remediation, with the appearance gate on every export
- The reading-order editor
- Right-to-left logical-order repair
- The remediation report, with the human-decision audit trail
What happens to your documents
A signed-out check is processed and discarded. Nothing is stored, and nothing is logged beyond the fact that a check ran.
Signed in, a check of your own file is kept in your History for seven days and then deleted, along with any repaired file made from it; you can delete it sooner. There is no alt-text generation and no model of any kind, so no image is ever sent anywhere.
This audience reads the privacy policy and checks it with a proxy, which is the right instinct. The policy →
Desktop and command line
Neither is available. There is no desktop build, no command line you can download, and no tier that sells you one. When they ship they will appear here and in thechangelog — not before. We would rather say what is shipping than what is planned.
