Who is The Grackle?

GrackleDocs Inc. is a private Canadian company focused on creating innovative accessibility software and is a trusted Google Partner for accessible output from Google Workspace. Our Grackle Suite consists of the only Google Add-Ons that checks and help remediate output from Google Workspace™ to make it accessible.
We help businesses manage the challenge to rapidly share or publish accessible materials online—easily—creating greater equity for the blind and visually impaired. Before we started Gracklin’, we acquired years of collective experience developing, marketing and selling industry-leading solutions for accessible electronic documents, globally

It is very important to note that although Grackle Suite catches a lot of accessibility issues, there are some issues it's not able to detect. That's why it's important to always review your work visually to find the issues hiding from the Accessibility Checks.
