Good to know before you scan (scope, certification, FERPA)Show
- Scope: finds images without alt text, automatic or placeholder alt text, slides without titles, Word files without headings, untagged PDFs, and PDF pages with no text. It cannot judge whether alt text describes the image well.
- Decorative vs. content: decorative images (borders, spacers) don't need alt text. Content images (diagrams, charts) do. You can mark an image decorative in the results.
- Not a certification: not a WCAG, PDF/UA, ADA, or full human accessibility review.
- FERPA: documents may contain student-identifiable records. Do not upload FERPA-covered or sensitive data unless your institution has approved that use. Supported files are processed in your browser and are not uploaded to CourseKit servers. Browser-first processing is not the same as institutional approval.
