What is Successible®?

Successible is the accessibility assistant built for non-coders — creators, educators, and small-business owners who want their content to be inclusive without needing to learn WCAG guidelines or call a developer.

It's as easy to use as spell check. But where a typo costs you a little polish, an accessibility gap costs you the person entirely — they can't use your page, so they leave, and they don't come back. In 2026, that's not a nice-to-have. It's what decides whether people stay on your platform or hop to the next one that actually works for them.

Successible scans your emails, landing pages, and posts for the issues that most commonly leave people behind — missing alt text, color contrast failures, skipped heading levels, missing video captions, and more — and tells you exactly what's wrong, why it matters, and how to fix it, in plain language.

Install it once. Keep building the way you already do. Run a check whenever you're ready to publish.
