About Scope

Scope is a set of free study apps that work with the Canvas or Brightspace course your school already uses. The Scope extension for Chrome searches your courses, Lectra is for reading and marking up PDFs on iPad, and Polya is a tutor that answers from your course materials. To learn more, see What is Scope?.
Yes. The Scope extension, Lectra, Lectra for Mac, Lectra Receiver, and Polya are all free. Polya applies daily fair-use limits so the service stays fair to everyone.
No. Scope is an independent product. It isn’t affiliated with or endorsed by Instructure, which makes Canvas, or D2L, which makes Brightspace. Your school doesn’t need to set anything up for you to use it.
Canvascope is Scope’s former name. The name changed to Scope in July 2026. You may still see the old name in a few places, such as the canvascope.org web address and some store and copyright details.
No. Scope helps you find, read, organize, and understand your course material. It can attach a file to an upload form, but it never submits work for you. Polya teaches through problems instead of handing over answers, unless you choose a study mode that allows full answers. You’re responsible for following your instructor’s rules and your school’s academic-integrity policy.
No. Lectra’s document intelligence uses Apple Intelligence on your device. Ask Scope and Polya use AI models from other companies to write answers. The privacy policies describe how your data is handled. To learn more, see Privacy at a glance.

​
Your account and privacy

Yes. The Scope extension, Lectra, and Polya share one Scope account. Sign in to each app with the same Google account to use the same Scope account everywhere. To learn more, see Your Scope account.
Not for everything. The Scope extension searches your courses without an account, and Lectra works without one if you choose Sign in later. Polya needs an account because it keeps your courses and conversations for you.
Only in Lectra. The other Scope apps sign in with Google. If you plan to use Lectra with the Scope extension or Polya, sign in to Lectra with Google too.
In Lectra, go to Settings > Account, and under Privacy & Data, tap Delete Account. You can also email support to ask for deletion. Deleting your account deletes it for every Scope app. For all the steps, see Delete your account and data.
No. Scope doesn’t use your notes, documents, or course materials to train AI models. Lectra’s summaries and answers are written on your device, so your documents don’t leave it for those features.
No. There are no ads in any Scope app, and Scope doesn’t track you across other companies’ apps and websites. Scope does count how many people use its apps, without recording what you search for, read, or write. To learn more, see Privacy at a glance.
No. Scope never needs your password or your school’s sign-in details, and it will never ask for them. Don’t send them to anyone who claims to be from Scope.
