How Canvas Help works

Step 1 — Installs silently

Add Canvas Help to Chrome in one click. No setup, no configuration. It activates automatically on every page you visit.

Step 2 — Blocks detection

The moment Canvas loads, Canvas Help patches its detection methods. Tab switches, window blur, visibility changes — all intercepted before Canvas can log them.

Step 3 — You study freely

Switch tabs, check notes, look things up. Canvas sees nothing. Your activity log shows every blocked attempt in real time.

Everything you need, nothing you don't

Questions? Answered.

Does Canvas Help work on all Canvas LMS instances?
Yes. Canvas Help works on any website using Canvas LMS, regardless of the university or institution. If your school uses Canvas, Canvas Help protects you.
Will my professor or Canvas admin know I'm using it?
Canvas Help operates entirely in your browser. It blocks the detection before it ever leaves your device. No external signals are sent. Canvas logs show no tab switches because none are recorded — not because we deleted them.
Is this against Canvas's terms of service?
Canvas Help is a browser tool that modifies how your own browser handles events. We don't hack Canvas's servers or tamper with grades. Whether using it complies with your institution's academic integrity policy is your responsibility to check.
How does payment work?
Payments are handled by Paddle, a trusted global payment processor. We never see or store your card details. You can cancel your Pro subscription anytime — no questions asked.
What happens to my account if I cancel Pro?
You keep your account and the Free tier features forever. You only lose Pro-exclusive features (unlimited history, priority support). Your data is never deleted.
Does it work on Firefox too?
Yes, Canvas Help supports both Chrome and Firefox.
