Word Atlas

Word Atlas is an illustrated vocabulary learning application designed specifically for IELTS test-takers. It transforms the process of memorizing English words into a visual and auditory experience.

It is ideal for:

• Students preparing for the IELTS exam
• Visual learners who benefit from images
• Anyone looking to expand their English vocabulary in an engaging way
• Learners who want to leverage scientifically-proven spaced repetition techniques

Getting started with Word Atlas is simple and requires no registration:

1. Visit the website at 0xlei.tech/words
2. The application loads directly in your browser
3. Your learning progress is saved locally on your device
4. You can begin exploring the 7,298 IELTS vocabulary words immediately

For the best experience, we recommend using a modern web browser like Chrome, Firefox, Safari, or Edge.

Word Atlas offers a comprehensive set of features to enhance vocabulary learning:

• Visual Learning: Each word is accompanied by a unique illustration to help create mental connections
• Audio Support: British and American pronunciations for all words, with example sentence recordings
• Spaced Repetition: FSRS algorithm optimizes review schedules based on your performance
• Interactive Exercises: Multiple practice modes including definition matching, sentence completion, and spelling
• Vocabulary Galaxy: A beautiful star map visualization of your progress across 19 topics
• Offline Access: Words and media are cached after viewing for offline study
• Progress Tracking: Local storage of your learning statistics and achievements
• Export/Import: Backup and restore your learning progress across devices

Word Atlas uses the FSRS (Free Spaced Repetition Scheduler) algorithm, which is more advanced than traditional spaced repetition systems:

• Adaptive Scheduling: Review intervals are calculated based on your memory performance, not just simple repetition
• Retention Target: You can adjust your desired memory retention rate (default is 90%)
• First-Answer Only: Only your first response to each review is counted toward accuracy statistics to prevent gaming the system
• Performance-Based: The system learns from your responses to better predict future recall

This approach ensures you spend your study time efficiently on words that need more attention, while moving quickly through words you've mastered.

Word Atlas is currently a web application designed to work in any modern browser on both desktop and mobile devices. While there isn't a dedicated native mobile app yet, you can access all features through your mobile browser at 0xlei.tech/words.

We are actively developing an iOS application with an enhanced mobile experience. The first round of iOS beta testing is currently being recruited. You can join the beta group by scanning the QR code on our website or contacting the developer through WeChat.

Privacy First: Word Atlas is designed with your privacy in mind. No account registration is required, and your personal learning data never leaves your device.

• Local Storage: All progress and statistics are saved locally in your browser's storage
• No Cloud Sync: We don't collect or store your personal learning data on our servers
• Export Functionality: You can export your progress data to back it up or transfer to another device
• Offline Access: Once you've viewed a word, its content (image, audio, text) is cached for offline access

This approach ensures complete control over your data while maintaining the convenience of a web application.

While Word Atlas stores your data locally, we still implement several security measures:

• HTTPS Connection: The website uses HTTPS to protect data in transit between your browser and our servers
• Browser Security: We rely on your browser's built-in security features to protect local data storage
• No Personal Information: We never ask for or collect personally identifiable information
• Regular Updates: We continuously update the application to address potential security vulnerabilities

For users who export their progress data, we recommend keeping these files secure and not sharing them publicly.
