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.
