Why install it
Everything you need to study uninterrupted
One free extension removes every paywall friction on Gizmo AI quizzes — and respects your privacy completely.
Unlimited hearts
The out-of-hearts modal never appears. Practice every question as many times as you want, with nothing blocking the screen.
Every hint unlocked
Hints that are normally gated behind a subscription are available on every question — no upgrade required.
Automatic & silent
It activates the moment you open a quiz, including in-app navigation from the decks page. No button to press.
Self-healing
Patch rules refresh every 2 hours through an automated pipeline, so the extension keeps working after Gizmo ships updates.
Zero data collected
No accounts, no cookies, no tracking, no telemetry. Everything runs locally in your browser and nothing is sent to us.
Open source
The full extension and patcher are public on GitHub. Read every line before you install — nothing is hidden.
How it works
Local patching, nothing leaves your browser
No servers are touched and no Gizmo account is changed. The extension rewrites only the quiz script running on your own machine.
Fetch the rules
In the background, the extension downloads a small set of text-replacement patch rules from the project's public GitHub repo.
Patch locally
It grabs Gizmo's own quiz script, applies the rules entirely inside your browser, and caches the result in private extension storage.
Study uninterrupted
The patched quiz treats you as subscribed, so hearts never run out and every hint is open. Leave the quiz and it steps aside.
