DuoXJS

DuoXJS is a free userscript utility for Duolingo that helps you switch between multiple accounts, automate daily routines (like streak keeping and quest saving), and automatically solve exercises.

Features

1. Two Solving Modes

• Native Mode: Automates XP, Gems, and Streak restoration in the background using direct requests, without loading the actual lesson interface.
• Auto Solver Mode: Injects SOLVE and SOLVE ALL buttons into the lesson footer. It reads questions on your screen and solves them automatically with configurable delay options (either a fixed speed or a randomized range to mimic human behavior).

2. EZ Quiz

• Simplifies standard lessons, stories, and listening challenges to make them incredibly easy and fast to complete.
• Shortens lesson lengths down to a configurable number of questions (default is 5).

3. Startup Automations

• Auto Reach Rank: Automatically runs in the background on startup until you reach your target league rank.
• Auto Keep Streak: Runs a quick lesson on launch to secure your daily streak.
• Auto Quest Saver: Automatically logs and claims your quest rewards on launch.

4. Account Manager

• Save multiple Duolingo profiles and switch between them instantly.
• View real-time stats (XP, Gems, Streak, and League Rank) for the active profile directly from the menu.

5. UI Customization

• Injects a clean floating menu overlay in the bottom-right corner of the page.
• Adaptive Dark/Light themes that automatically match system preferences or Duolingo's colors.

Installation

1. Install a Userscript Manager:

• Install Tampermonkey or Violentmonkey in your browser.

• Click on the raw link of DuoXJS.user.js to install it.

• Navigate to duolingo.com. You will see the floating control panel in the bottom-right corner.

How to Use

1. Settings & Customization: Click the floating menu handle in the bottom-right corner of the page to open the panel.
2. Manage Profiles: In the Account Manager tab, click SAVE CURRENT to register profiles and switch between them at any time.
3. Set Solving Delay: Toggle Random Speed to set minimum/maximum ranges, or input a fixed delay (in milliseconds) to control solving intervals.
4. Run Automation: Toggle your preferred background automation settings (Auto Reach Rank, Auto Streak, etc.) and click the main action button to start.

Privacy & Storage

• Local Storage: All settings, accounts, and session tokens are saved locally in your browser's private storage using the dx_ prefix.
• No Tracking: No personal information or usage data is sent to external servers. The script only occasionally queries its GitHub repository to check for updates.
