About

LeetComplete – Intelligent C++ Autocomplete for LeetCode

LeetComplete enhances the LeetCode coding experience by bringing modern IDE-style autocomplete directly into the browser. Instead of memorizing STL APIs or repeatedly switching to documentation, get fast, context-aware suggestions while solving problems.

Designed specifically for competitive programmers and interview preparation, LeetComplete helps you write C++ code faster with minimal interruptions.

✨ Features

1) Semantic Autocomplete

Receive context-aware suggestions based on the type of your variables.

Example:
priority_queue<int> pq;
pq.

Suggestions:
{
push()
pop()
top()
empty()
size()
}

The extension analyzes your code and recommends methods that belong to the detected C++ STL type.

2) Prefix (Trie-Based) Suggestions

Start typing STL names and instantly receive completions.

Examples:

vec
→ vector

pri
→ priority_queue

unordered_
→ unordered_map
→ unordered_set

Fast prefix lookup helps reduce typing and improves coding speed.

You can choose Your Completion Mode
Customize the behavior to match your workflow.
Choose between:
