Master LeetCode & NeetCode 150 problems with spaced repetition - A powerful CLI tool that helps you remember coding patterns and ace technical interviews using proven learning science.
A terminal-based spaced repetition system (SRS) for mastering coding interview problems. Built with Go and SQLite, this tool intelligently schedules LeetCode/NeetCode problem reviews to maximize retention and prepare you for FAANG interviews.
- 🧠 Spaced Repetition Algorithm: Scientifically-proven learning technique that schedules coding problem reviews based on your performance - study smarter, not harder
- ⚡ Interactive CLI/REPL: Clean terminal interface for focused studying without browser distractions
- 💾 SQLite Database: Lightweight, persistent storage tracks your progress locally - no account required
- 📚 NeetCode 150 Integration: Pre-configured with the complete NeetCode 150 problem set covering all essential interview patterns
- 🎯 Progress Tracking: Monitor your mastery of data structures, algorithms, and problem-solving patterns
- 🚀 Offline-First: Study anywhere without internet dependency

The spaced repetition algorithm automatically determines which problems you should review based on your past performance.
On first run, the app will attempt to seed the problems table with the NeetCode 150 list from neetcode_150.json in the project root.
Expected JSON format:
[
{ "title": "Two Sum", "difficulty": "Easy" },
{ "title": "Valid Anagram", "difficulty": "Easy" },
{ "title": "Group Anagrams", "difficulty": "Medium" }
]If the file is missing, seeding is skipped and you can add it later and rerun with a fresh database.
GoStudyNeetCode implements a spaced repetition system (SRS) - the same learning technique used by Anki, SuperMemo, and other proven study tools.
- ✅ Correct answers → Review interval increases exponentially (1 day → 3 days → 7 days → 14 days...)
- ❌ Incorrect answers → Problem resets for frequent review until mastered
- 🎯 Adaptive scheduling → The algorithm learns your pace and adjusts difficulty accordingly
This ensures you focus on weak areas while maintaining knowledge of mastered patterns - perfect for interview preparation and long-term retention of coding concepts.
- Go - Fast, compiled performance with simple concurrency
- SQLite - Zero-configuration embedded database
- go-sqlite3 - CGo-free SQLite driver
- Web dashboard for statistics visualization
- Custom problem set support (import your own questions)
- Topic-based filtering (arrays, graphs, dynamic programming, etc.)
- Export/import progress for backup
- Multi-device sync
