📢 We're moving our documentation to a new system on July 1. Check out the new version now. 📢

UDOIT – or the Universal Design Online Content Inspection Tool – is a tool available in all Canvas courses that scans your course and flags any accessibility issues, and provides information on how to fix the issues. UDOIT  scans for typical accessibility issues including:

  • Use of headings in page structure
  • Alternative text for images
  • Table headers
  • Color contrast
  • Video captions

Notably, UDOIT does NOT scan files that you upload to Canvas – for example, Word documents, PowerPoint slides, and PDF files. See our Creating Accessible Digital Materials resource page for more information on how to create accessible docs, slides, and PDFs.


UDOIT is already installed in all Canvas courses.


To use the UDOIT tool:

  1. click the UDOIT link in the course navigation menu on the left-hand side of your Canvas course site.
  2. On the UDOIT page, make sure the Select Content “All” checkbox is ticked.
  3. Click the green “Scan This Course Button” to initiate the accessibility review.
  4. Once the scan is complete, UDOIT shares a report that includes any issues flagged during the scan.
  5. To review and fix issues, click the toggle next to the section title to view issues for the section, and click the green UFIXIT button to remediate the issue. (NOTE: not all issues will be fixable via the UFIXIT interface. If you have questions, please contact us for a conversation.)
