Enables teachers to remotely monitor and control student Chromebook screens, manage classroom activities (quizzes, website blocking, screen sharing, messaging) in real-time during class, solving the challenge of managing distributed digital learning environments.

1) Student installs extension on Chromebook logged in with school Google account. 2) Extension auto-detects Google identity, checks domain license at admin.gto.to, and determines server configuration. 3) Extension connects to ClassroomGo signaling server via WebSocket and reports student as online. 4) Student appears in teacher's control panel. 5) Teacher can monitor screen, broadcast content, block sites, send quizzes, exchange messages, and use AI features. 6) Student can raise hand, answer quizzes, chat with teacher, and use AI assistant for assigned questions. 7) Student can also join sessions via QR code/PIN if not auto-detected.

Target users: Students on Chromebooks in K-12 and educational institutions using the ClassroomGo platform / Primarily Taiwanese schools (Traditional Chinese default) with multilingual support (English, Japanese, Korean)

Monetization

No paid features detected

The student extension itself does not contain payment UI, upgrade prompts, subscription checks, or feature gating. It does perform a domain-level license check via admin.gto.to/special-license/api/statusDomain/ (background.js:712) to determine which servers to connect to and whether to allow the device, but when no license is found it falls back to default servers (background.js:726-741). The licensing is institutional — schools purchase ClassroomGo service access for their domain. The student extension is freely installable but benefits from the school having a valid license. No Stripe, payment processing, or subscription management code exists in the extension source.

Confidence: 78
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension requires the student to be logged into their Chromebook with a Google account. It uses chrome.identity.getProfileUserInfo() to get the user's email and chrome.identity.getAuthToken() for OAuth. If no email is found, it calls signin() which triggers interactive Google OAuth (background.js:317-321, 905-935). The license check at admin.gto.to is also based on the user's email domain. The store description explicitly states '學生受控端支援已登入之Chromebook' (student endpoint supports logged-in Chromebooks). An alternative join-by-PIN flow exists (background.js:3664) that accepts a student name, but the primary auto-connect flow requires a Google-signed-in Chrome profile.
