AdButter

Help us measure scams in ads.

AdButter is a free Chrome extension from CollectiveMetrics.org, a nonprofit. It helps our community fight scam ads by quietly saving the ads on websites you visit. See what it captures, and control where it runs.

How it works

Measure scam ads

AdButter silently saves ads from certain websites you visit, helping our community measure and identify scam advertisements across the web.

See what's saved

Browse through all the ads AdButter has captured. Full transparency—you always know exactly what data is being collected.

You're in control

Turn AdButter off on any site at any time. You decide where it runs and where it doesn't. Your browsing, your rules.

Join the fight against scam ads

Every install helps. The more people running AdButter, the better we can measure and call out scams and low quality ads. A project by CollectiveMetrics.org. Read the Terms of Service & Privacy Policy.
