Every publicPDF, readableby everyone.

Plainproof finds the PDFs you publish, drafts accessible versions, sends a person only what needs judgment, and gives you signed proof of what was checked.

Free. No account.

Example agenda from an invented city. The blue marks show the order a screen reader will follow.

PDFs are web content, and web content has a date.

Under ADA Title II, state and local governments must make web content, including PDFs, meet WCAG 2.1 AA.

Many public PDFs have no structure, so a screen reader hears nothing useful. This is one page, read both ways.

What a screen reader says

Page 1 of 14. $4.42. Received. Proposed. Public hearing. City of Harbor Point. +8.1%. Public comment. 6:30 p.m. Commercial. Call to order. Current. Agenda. Image.

An illustration. What you hear depends on the file and the screen reader. A scanned page can read as nothing at all.

Find it, fix it, prove it.

  1. 1 Find

    We crawl the sites you run and the agenda platforms they link to, and count the PDFs we find.

  2. 2 Fix

    AI drafts the tags, reading order, table headers, text and alt text. A person decides anything the machine is unsure about.

  3. 3 Prove

    A validator checks the finished file, a person approves it, and you keep a signed record of both.

Your team answers questions. It doesn't learn PDF tags.

The machine settles what it can and asks about the rest. Each answer is one key. Try it.

14 items decided by people. 212 settled by the machine, not reviewed by a person.

In plain words

Software drafted this file's structure. People decided what the software could not settle. Independent checks ran on the finished file. This record states what was checked. It is not a legal opinion or a guarantee of conformance.

Signed HMAC-SHA256 3ab1f06e94c2d7581e0fb26a7c43d98e

A record you can hand to counsel.

Every released file comes with one. It names what checked the file, what the check found, and who decided each thing the machine could not settle.

It says what was checked. It does not say you are compliant.

Questions.

Something else? Talk to us.

Does this make us compliant?
No tool can settle that for you. We state what was checked, by what, and by whom. The result supports your accessibility work. It is not a legal guarantee.
Do we have to fix every old PDF?
No. The rule has exceptions, such as archived content and older files no one needs to use a service. You decide which applies, and Plainproof records it and why. You still answer requests for those files.
Does AI do all of it?
No. AI drafts. A person decides anything the machine is unsure about, and by default nothing is released until a person approves it.
Who sees our documents?
Your team and the people you invite. Page images go to an AI provider to draft the fixes, with no training on your files, and you can turn that off. Our staff can open your account only through a logged, time-limited grant.
What about scanned files and forms?
Scanned pages get real text, and a person checks any name, date or amount the machine is unsure of. Forms get labels and a tab order. Hard forms, maps and complex tables are priced as specialist pages.
What about next week's agenda?
Files you post after your date get no exception for older documents. That is what Flow is for: the agendas, minutes and forms you keep posting.
