About
Listudy is a free and open-source chess improvement platform built around the science of spaced repetition — a memorization technique proven to maximize long-term retention by scheduling reviews at optimal intervals. Rather than passively studying chess, users actively engage with their material across four core training pillars. **Openings**: Build and drill your personal opening repertoire by playing through lines interactively. Listudy tracks which moves you know and resurfaces weaker areas over time. **Tactics**: Train with thousands of tactical puzzles sourced from real games. Includes standard tactics, Blind Tactics (solve while seeing the board from 2 moves ago to develop visualization), and Pieceless Tactics for advanced pattern recognition. **Endgames**: Practice fundamental and complex endgame positions against Stockfish, the world's strongest open-source chess engine, to build deep, reliable endgame technique. **Community & Openness**: Listudy is fully open source (available on GitHub) and welcomes community contributions — bug fixes, translations (10+ languages supported), and new studies. Users can also create and share custom studies. The platform includes a daily puzzle, curated chess book recommendations with Grandmaster endorsements, and an active blog covering chess learning strategy. With no paywalls, no subscriptions, and the ability to self-host, Listudy is ideal for dedicated chess students who want a principled, cost-free training regimen.
Key Features

- Opening Repertoire Trainer: Build a personal opening repertoire and drill it interactively, with the system tracking weak spots and prioritizing moves you struggle to remember.
- Blind & Pieceless Tactics: Advanced tactical modes that hide the current board position to force visualization — a powerful method for developing board sight and calculation depth.
- Endgame Training vs. Stockfish: Practice endgame positions against the world's strongest open-source chess engine to build reliable technique under realistic competitive pressure.
- Custom Studies & Community Content: Create, share, and study custom training sets. Contribute bug fixes, translations, or new content via the open-source GitHub repository.
Use Cases
- A club player building and memorizing a new opening repertoire using interactive spaced repetition drills.
- A chess student sharpening tactical pattern recognition by solving thousands of puzzles from real games.
- An improving player developing deep endgame technique by practicing positions against Stockfish.
- A player enhancing board visualization and calculation by training with Blind Tactics mode.
- A chess coach or contributor creating and sharing custom studies with students or the open-source community.
Pros
- Completely Free & Open Source: No subscription, no paywalls, and self-hostable — users retain full control and can modify the software to suit their needs.
- Science-Backed Learning Method: Spaced repetition is one of the most rigorously validated memory techniques, making study sessions more effective per hour than traditional methods.
- Multi-Modal Chess Training: Covers the full spectrum of chess study — openings, tactics, endgames, and visualization — all in one integrated platform.
- Multi-Language Support: Available in 10+ languages, making it accessible to a global chess community.
Cons
- No Dedicated Mobile App: Listudy is web-only with no native iOS or Android app, which may limit convenience for users who prefer mobile-first study sessions.
- Chess-Only Scope: The platform is exclusively focused on chess — users looking for general learning or other game training will need to look elsewhere.
- Community-Dependent Content Growth: As an open-source project, the breadth of available studies and features depends on volunteer contributions, which can be slower than commercial platforms.
Frequently Asked Questions
What is spaced repetition and why does Listudy use it?
Spaced repetition is a learning technique that schedules reviews of material at increasing intervals just before you're likely to forget it. Listudy applies this to chess to help you memorize openings, recognize tactics, and retain endgame knowledge far more efficiently than random or massed practice.
Is Listudy really free?
Yes. Listudy is completely free to use and is open-source software. There are no premium tiers, subscriptions, or hidden costs. You can also download and self-host the software from GitHub.
What are Blind Tactics?
Blind Tactics is a training mode where you solve tactical puzzles while only seeing the board position from two moves ago. This forces you to visualize the current position mentally, which is a highly effective way to improve your calculation and board visualization skills.
Can I create my own studies on Listudy?
Yes. Listudy allows registered users to create custom studies, which can then be shared with the community or used for personal training.
How does endgame training work on Listudy?
Endgame training pits you against Stockfish, a top-tier open-source chess engine, in specific endgame positions. This gives you realistic, high-quality opposition to help you internalize the principles and techniques needed to convert endgames over the board.
