Key features

Fullscreen & Kiosk-Ready

Designed for managed Chromebooks. Students can’t leave the app; admins have a hidden PIN exit.

First-Save Gate

Typing is disabled until the file location is chosen, protecting work from the very start.

Autosave Every Minute

Writes to the chosen file each minute and also keeps a backup in OPFS for resilience.

Open Existing Work

Recover and continue writing from the last saved file if a device loses power.

Printing That Matches

Clean header with center, candidate, title, date + “Page X of Y”. Content paginated to avoid overflow.

Hardened Editor

Spellcheck off, paste/context-menu/drop disabled by policy, with optional theme & zoom controls.

Useful shortcuts

Printing for exam scripts

Consistent layout

The app paginates your text for print with a per-page header and page count. No cut-off lines, no scrollbars.

  • ✔A4 by default (Letter supported)
  • ✔Date format: DD/MM/YYYY
  • ✔Header fields: Center number, Candidate ID/Name, Exam Title

Tips

Use installed printers on the Chromebook. In managed environments, pre-select printers via policy.

Need Letter paper? You can toggle a flag in the app to use 279mm height and your preferred margins.

Deploy on Chromebooks

Install as a PWA

  1. Host the app files (PWA + service worker) — Netlify works great.
  2. Open in Chrome → menu → Install app.
  3. Launch in full-screen; the app uses display: fullscreen.

Managed kiosk (admin)

  1. Force-install the PWA via Google Admin Console.
  2. Assign as a single-app kiosk for exam OU.
  3. Provide the admin PIN to invigilators for emergency exit.

Privacy & reliability

Local-first
Saves directly to the student’s chosen file location. No cloud dependency.
Offline-ready
Service worker caches the app shell; autosave keeps writing even without connectivity.
Resilient
OPFS backup mirrors the latest text between timed saves.
