What you need first
Two short strings your college was given when it joined the pilot: a consumer key and a shared secret. They identify your college to Glass, not you. If nobody at your college has them yet, write to us and we will send them to the person who runs Canvas there.
The three steps
Add the app. In your course open Settings, then the Apps tab, then View App Configurations and + App. Set Configuration Type to By URL. Name: Glassability. Paste the consumer key and shared secret. Config URL: https://accessibility.glass/lti/config.xml. Press Submit.
Find it in the navigation. Reload the course. Glassability appears in the course navigation on the left. If it is hidden, open Settings, the Navigation tab, drag it into the visible list and save. Students never see it; the item is for the instructor's roles only.
Connect and let it scan. Open Glassability. If your college has registered it with Canvas you will see one button, Connect with Canvas; Canvas asks whether Glassability may act for you, and you say yes. Otherwise the page walks you through making an access token in your own Canvas settings and pasting it. The first scan starts on its own, and the page turns into your report when it is ready, usually within minutes.
What you have just allowed, and how to take it back
Glass reads the course's pages, assignments, discussions, quizzes, files and modules as you, and writes to them only when you press a button on your report. It never reads student submissions, grades or the people list. You can withdraw the permission at any time under Account, Settings, Approved Integrations in Canvas; Glass stops the moment you do. Removing the app from the course removes the navigation item; anything Glass changed in the course stays as it is, with a before copy on file.
Where the AI comes in
Glass uses language and vision models to draft what a person would otherwise have to type: the description of an image, the wording of a link, a heading, the check of a caption against its audio. The models are shown course content only. They never see student submissions, grades or the people list, because Glass never holds those. Every draft waits for your press, and every change is logged with a copy of the content before and after.
For Canvas administrators
https://accessibility.glass/lti/1.3/config.json, turn it on, send us its client id, and add Glassability by client id under Admin, Settings, Apps. It appears in every course's navigation at once, and in the account navigation for administrators, where it opens the roll-up of what has been scanned and repaired under that account. The By URL configuration above works at the account level too.Glassability uses the LTI 1.1 course placement, which any instructor can add to their own course unless the college has locked external apps. Where it is locked, the administrator's install above is the route. What Glass keeps and the free pilot terms.
