Not LeetCode. Not Flashcards.
Real code. Ten minutes. From memory.
Spaced repetition keeps you sharp without the grind.
Spaced repetition typing drills for Python, JavaScript, SQL, GDScript, and Rust.
Why Syntax Cache?
You know the language. You just keep blanking on the syntax.
Retrieval practice and spacing are two of the most consistently supported learning strategies.
Actually Write Code
Not flashcards. You type real syntax that executes. Build muscle memory, not just recognition.
Spaced Repetition
The algorithm tracks what you forget and brings it back right before it fades. You only practice what you need.
1,800+ Exercises
Python, JavaScript, SQL, GDScript, and Rust. From basics to advanced patterns: comprehensions, decorators, hooks, async/await, and more.
Interview Prep
Algorithm patterns (Two Pointers, Sliding Window, BFS/DFS), data structures, and design patterns (Strategy, Factory, Observer). Build real projects as capstones.
Game Mode (Optional)
Turn practice into a dungeon crawler. Defeat enemies with correct answers. Level up. Or skip it entirely. The core practice works great on its own.
How It Works
Pick up where you left off. Daily practice takes just 10 minutes.
Example: 10 prompts in 6 minutes. The 2 you missed will come back tomorrow.
Get Daily Exercises
Log in and the algorithm tells you what to practice today.
Type From Memory
Write actual code syntax without peeking at references.
Algorithm Adapts
Get it right and the interval grows. Get it wrong and it comes back sooner.
Pick Your Path
Focus on one language or practice them all. Every track covers the syntax you actually write at work.
Python
For devs who keep googling comprehensions and f-strings
Comprehensions, decorators, f-strings, *args/**kwargs. String methods, error handling, classes, collections.
"Get user age, default to 0 if not found"
JavaScript
For frontend devs tired of Promise.all vs allSettled lookups
Async/await, promises, modules, DOM, React hooks, TypeScript. Closures, array methods, this-binding.
"Wait for all promises, even if some fail"
TypeScript
For devs who want generics and utility types to feel natural
TypeScript type system, generics, utility types, and type narrowing.
"Extract the return type of a function"
SQL
For anyone who forgets WHERE goes after JOIN, not in it
JOINs, window functions, NULL handling, pagination. CTEs, subqueries, GROUP BY/HAVING, safe writes.
"Filter rows BEFORE joining"
GDScript
For Godot devs building muscle memory on nodes and signals
Nodes, signals, exports, Vector2. Movement, scene instancing, collisions, tweens, projectiles.
"Move the player 100 pixels right"
Rust
For systems programmers and safety-focused developers
Master Rust syntax through spaced repetition. Practice ownership, borrowing, lifetimes, pattern matching, and traits until they become automatic.
"Write ownership transfer syntax"
Design Patterns
Observer, Strategy, Factory, and more. Classic patterns with implementations in Python, JavaScript, and GDScript.
Interview Algorithms
Two Pointers, Binary Search, Sliding Window, BFS, DFS. Templates and patterns for coding interviews.
Frequently Asked Questions
Everything you need to know about Syntax Cache
How does Syntax Cache work?
You get a prompt and type real code that executes. Get it right and the app waits longer before asking again. Get it wrong and it comes back sooner. Over time, the syntax sticks.
How is this different from LeetCode or flashcards?
Flashcards show you an answer and ask if you knew it. LeetCode gives you novel problems to solve. Syntax Cache makes you type real code from memory, the same patterns you use at work. The spacing algorithm handles long-term retention so you don't need to cram.
What programming languages does Syntax Cache support?
Python, JavaScript, SQL, GDScript, and Rust. Over 1,800 exercises covering basics to advanced patterns including list comprehensions, decorators, React hooks, and async/await.
Is Syntax Cache free?
Yes. The free tier gives you 10 exercises per day with full access to all content. The Pro plan removes the daily limit so you can practice as much as you want.
Do I need to install anything?
No. Everything runs in the browser. Just sign up and start typing.
Do I lose progress if I stop practicing?
No. Your progress is saved. When you come back, the algorithm picks up where you left off. Exercises you were close to mastering might need a refresher, but you won't start from scratch.
Can I practice without the game mode?
Yes. Game mode is completely optional. The core typing practice works great on its own. Many users never touch the game.
Does Syntax Cache help with coding interviews?
Yes. There are exercises for algorithm patterns (Two Pointers, Sliding Window, BFS/DFS), data structures, and design patterns (Strategy, Factory, Observer). Capstone projects tie them together.
Is there a game mode?
Yes. Game mode turns practice into a dungeon crawler. You fight enemies with correct answers, level up, craft items, and explore. It's completely optional. The core practice works fine without it.
