Quoin
Catches the editorial mistakes before the post is published: empty links, skipped headings, missing alt text.
== Description ==
Accessibility problems are cheapest to fix in the editor and most expensive to fix in an audit. Quoin runs a set of checks in the pre-publish panel — heading order, alt text, link text, table headers, contrast on inline styles — and links each finding to the block that caused it.
Findings are advisory, not blocking. A check that prevents publishing gets disabled within a week by someone on a deadline, and then nothing is checked at all.
Checks are individually switchable and each one explains what it is checking and why, in a sentence, where the finding appears.
== Screenshots ==
Numbered the way they ship in /assets/. Click any one to see it full width.
== Installation ==
- Install and activate the plugin.
- Publish something. The panel appears before you confirm.
- Switch off any check that does not apply to you under Settings → Writing.
Nothing is blocked. Every finding is a link to the block, which is what makes it get fixed.
== Frequently asked questions ==
Can I make checks blocking?
One setting, per check, off by default. Consider what happens on a deadline before you use it.
Does it check the whole site?
A bulk scan exists under Tools, which is how you find out how far behind you are.
