LeetCode Autocomplete

IDE-style autocomplete for LeetCode: type-aware methods, keywords, snippets. No AI, no setup, no data collection.

LeetCode's code editor doesn't give you the autocomplete you're used to from an IDE. This extension adds it. As you type, a suggestion list appears with the language's keywords, common standard-library functions and the variables you've already written. Press Tab or Enter to accept a suggestion. When you type a dot after a variable, the list shows only the methods that variable actually has. A list shows list methods, a string shows string methods, and a hash map shows map methods. Short templates for common loops and functions are included too. It works in every language LeetCode offers, with the type-aware method suggestions in the most popular ones. It is not AI and never writes code for you. It only completes what you're typing. Everything works as soon as it's installed. If you want to change anything, click the toolbar icon to turn individual features on or off. Your privacy: your code never leaves the page, nothing is collected or sent anywhere, and the only thing saved is your on/off settings, on your own device.
