Cerolingo is a lightweight browser extension designed as an automation and customization utility for Duolingo, running directly inside your web browser to streamline your learning experience.
Cerolingo includes an Auto-Answer Bot for story lessons, an instant Audio Blocking mode to skip talking animations, Story Map Highlighting, a Legendary Lesson Bypass, a Point Exploit, and a full All-in-One Mod Menu to control everything directly on the page.
The Mod Menu overlays directly on Duolingo so you can toggle modules and change settings without opening your browser's extension popup. You can double-click the title bar anytime to minimize or hide the menu, and drag it around smoothly on both desktop and mobile screens.
Cerolingo is available as a browser extension for Google Chrome, Mozilla Firefox (desktop), and Firefox for Android mobile. It fully supports both duolingo.com and the Chinese version, duolingo.cn.
