Cidi Labs UDOIT (short for Universal Design Online content Inspection Tool) is a Canvas-integrated accessibility checker that helps instructors and staff identify and fix accessibility issues in their course content.

UDOIT scans your Canvas course content for accessibility problems and guides you on how to fix them. UDOIT reviews Canvas pages, assignments, discussions, files, and other content to detect common accessibility issues (like missing alt text, poor heading structure, insufficient color contrast, or inaccessible PDFs) then provides actionable guidance, explaining why an issue matters and how to correct it—often linking directly to the content that needs attention. Get started with the UDOIT User Guide.

Follow these steps to enable UDOIT in your Canvas course.

Step 1: Open your Canvas Course

Sign in to and open the Canvas Course you wish to enable UDOIT in. 

Step 2: Settings

Navigate to and select the Course Settings link from the left side navigate.

Step 3: Navigation

On the Course Details page, choose the Nagivation option at the top of the screen.

Step 4: Enable UDOIT

Navigate to the bottom of the page to view the list of disabled tools available for your Canvas course. Select the menu button (three dots) next to the UDOIT tool, then choose Enable. Select Save to activate your new settings.

The UDOIT tool will appear in your Course Navigation. Once enabled use the UDOIT User Guide to learn how to scan for and fix accessibility errors in your course. Remember you will need to enable UDOIT for each of your courses.
