Accessible Docs, Slides and Sheets, without the guesswork.

Legibright checks the file you have open, explains each problem in plain language and fixes most of them in one click. It works in Google Docs™, Slides and Sheets, and your document content never leaves Google.

One add-on for all three

The same checks and the same sidebar in Google Docs™, Slides and Sheets.

Fixes, not just flags

Turn bold text into real headings, typed dashes into real lists, pale text into a passing colour, and put slides in the right reading order, in one click. Type alt text straight into the sidebar.

The right standard for your country

WCAG 2.0, 2.1 or 2.2 at level AA, chosen for where you are: the ADA Title II rule in the US, EN 301 549 in Europe, and WCAG 2.2 for UK and Australian public bodies. You can change it any time.

Your files stay yours

Legibright reads only the file you have open, inside Google. No document text is sent to us, and there is no AI guessing at your content.

Honest about its limits

A few things Google does not let add-ons read, such as table header rows in Docs. Legibright lists them as "check by hand" with the exact steps, instead of pretending they passed.

Made for evidence

Every check is dated and names the rules version it used. Items you mark as OK stay on the record, and Pro gives you a report to keep.

How it works

  1. Open a Doc, Slides deck or Sheet and click the Legibright icon on the right.
  2. Click Check. Problems are grouped by rule, with where they are and why they matter.
  3. Click Fix, or Go to and fix it yourself. Check again to see the count fall.

Who it is for

Schools, colleges and universities

In the US, the ADA Title II rule asks public schools and colleges to make their online documents meet WCAG 2.1 AA from April 2027 (larger bodies) or April 2028 (smaller ones).

Councils and public bodies

UK, EU, Canadian and Australian public sector rules already cover documents you publish.

Anyone who shares documents

Clear headings, real lists, good contrast and alt text make documents easier for everyone, not only screen reader users.

A note on "compliance"

No automated tool can prove a document is fully accessible, and Legibright never claims to. It helps you meet WCAG 2.0, 2.1 or 2.2 AA by catching the problems a machine can find and telling you exactly what to check by hand.

Questions

Is the free plan really unlimited?

Yes. Unlimited checks, all the guidance and Go to, with no watermarks and no monthly limits. Pro adds one-click fixes, Fix all, Mark as OK and the report.

Does my document go to your servers?

No. Legibright runs inside Google and reads only the file you have open. The only thing we ever receive is your email address, to look up whether you have Pro.

Which standard does it check?

WCAG 2.0, 2.1 or 2.2 at level AA, picked automatically from your Google language and region. Change it in Settings. Your choice is pinned to each file, so later checks stay comparable.

What happens when the rules change?

Each check names its rules version, for example "Rules 2026.11". When a rule changes, anything you marked as OK under the old rule is shown again so you can look at it once more. Nothing else changes in files you have already checked.

What can it not check?

Floating images in Docs, table header rows in Docs and chart descriptions in Sheets, because Google does not let add-ons read them. They appear as "check by hand" with steps. It also cannot judge whether alt text is good, only whether it is there.

Can my school pay by invoice?

Yes. The school licence covers everyone on your school email domain for $399 a year. Choose Pay by invoice in the sidebar, and we email an invoice payable within 30 days. Pro starts straight away.
