Teacher-student screen sharing and classroom management tool for Google Classroom

Enables teachers to monitor, control, and interact with student devices during online or hybrid classes using Google Classroom, addressing the need for remote classroom supervision and engagement.

1. Teacher installs extension and logs in with Google account. 2. Extension connects to Google Classroom to fetch class/roster data. 3. Teacher selects a class and students. 4. Teacher can share their screen, view student screens, lock screens, send messages, or push URLs to students via the Sateraito backend service.

Target users: Teachers / Students / Educational institutions using Google Classroom

The background.js is heavily minified/obfuscated, making detailed code flow analysis difficult. However, manifest and UI HTML provide sufficient evidence for the three decisions. The extension relies on external backend services (App Engine/Firebase) which are not fully inspectable from the source package alone.

Monetization

No paid features detected

No evidence of paid features, subscription plans, or payment processing within the extension code or UI. The extension is free on the Chrome Web Store. While the vendor (Sateraito) may have paid plans for their broader service (sateraito.jp), the extension itself does not gate features behind a paywall, call billing APIs, or display upgrade/payment UI. The keyword matches for 'license' refer to open-source library licenses (MIT, Apache), not paid licenses.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension uses Google OAuth2 (manifest.json oauth2 section) to authenticate users via their Google account. The UI in index.html contains a 'sign_in' button (line 497) labeled 'ログイン' (Login). The extension requires a Google account to access Google Classroom APIs (classroom.courses.readonly, classroom.rosters.readonly, etc.) and to connect to the Sateraito backend services (Firebase/App Engine) for screen sharing functionality. Without login, the core workflow of managing students and sharing screens cannot be initiated.
