The fastest Duolingo XP gainer, working as of November 2025.
The script does not work using Violentmonkey, either.
If you are using preview.duolingo.com, some changes Duolingo has made might break Duolingo Pro. Please updating to 9.6.6 which should have some fixes
The "Solve" and "Solve All" buttons do not appear during lessons. I am using Tampermonkey.
