Three ways to run a session
Pick the level of support that fits the work.
Exam
Tests & quizzes
Keep the quiz on its allowed sites. Attention changes move through a grace period and warning before teacher unlock is needed. Other extensions can be paused, then restored.
Focus session
Reading & classwork
Use the sites you choose and quiet website notifications. A countdown keeps time; nothing locks, and early endings appear in the summary.
After the activity
A record you can read fairly
Students share a report from their device. Start with the summary, then use the timeline to understand what happened.
Signals are observations, never accusations. Notifications, input tools, and ChromeOS gestures can cause an attention change without cheating.
A verification code helps reveal casual edits to the record. It does not prove who produced it or what happened off-screen.

Know what the extension can see
Inside Chrome
- Keep the activity on the allowed sites and record attempts to leave.
- Note attention changes, with context in the report.
- Temporarily pause eligible extensions and mute site notifications when enabled.
- Check setup with a practice run before class.
Outside its reach
- Phones, other devices, paper notes, and apps outside Chrome.
- Cameras, microphones, and screenshots: it never uses them.
- A live teacher dashboard: this standalone extension does not stream activity.
- A determined student using another browser or profile.
Names on reports are typed by students, and a check code catches casual edits, not determined ones. Read the full list of limits
Before your first session
Start with a short practice run
Install on the devices you plan to use, check the activity site, and try a session before class. School policies may block Developer mode or unpacked extensions, so ask IT to verify a managed device first.
The extension isn’t in the Chrome Web Store, and there’s no setup yet for schools to install it automatically on managed devices. Reports stay on the student's device until they choose to share them; they contain a self-entered name and a timeline, never page content.
