✨ School Broadcaster — Full-Screen Announcements, Powered by Google Sheets
Transform school environment with School Broadcaster, a simple yet powerful Chrome extension that displays full-screen announcements across Chromebooks, Macs, and Windows PCs. Designed specifically for K–12 schools, this tool allows staff to instantly share important messages, reminders, and events—without disrupting workflow.
🧠 How It Works
• The School IT Department connects the extension to district owned shared Google Sheet(s) and configures the extension and the various google sheets so that others will enter screensaver information into them.
• Authorized staff (e.g., principals, secretaries, or teachers) can add or update announcements in the appropriate sheet(s)
• The message(s) automatically appears on student or staff devices running Chrome, in a clean full-screen format similar to how a screensaver works
🖼️ Text or Image-Based Announcements
School Broadcaster supports text or image-based messages including animated gifs. Canva is a great tool to assist you. You can display plain text, like “Wear Blue on Friday,” or link to an image (hosted online) such as a flyer, schedule, or custom graphic. It’s a flexible canvas for your school’s needs—whether you want to communicate quickly or visually.
💡 Use Cases
• Morning announcements
• Reminders for dress-up days, assemblies, or lunch menus
• Rotating digital signage for hallways, offices, or media centers
• Timely notifications during testing days or special schedules
✅ Key Features
• Instantly update announcements from a central Google Sheet—no technical skill required
• Works across platforms: Chrome OS (Chromebooks), macOS, and Windows
• Full-screen display ensures the message is seen—ideal for kiosk or locked-down modes
• Minimal setup: just install the extension and configure the sheet ID,
• Secure and private: Google Sheet can be shared only with staff who need access
🔓 Free Version Details
The free version allows a single message entry using cell A1 of your Google Sheet. This message can be plain text or a direct link to an image (e.g., a PNG or JPG hosted on a public site like Google Drive). For schools that want more advanced features—like multiple rotating messages, an affordable premium version is available.
🔒 Built for Schools
Whether you’re broadcasting a quick reminder or displaying a rotation of daily messages, School Broadcaster gives you a low-effort, high-visibility solution to school-wide communication. It’s especially helpful when students or staff are already working within the Chrome browser—no app switching required.
🚀 Easy Setup by the school district IT department
1. Install the extension
2. Paste in your Google Sheet ID
3. Start posting announcements — it’s that easy!
