Litcode is a Chrome extension developed by kaanaksoyaz that adds a new dimension to interview preparation on the Leetcode platform. While interview practice is typically a solitary endeavor, Litcode allows users to create lobbies and compete against friends while solving Leetcode questions.

This extension injects excitement into the process by keeping track of who solves questions first and providing a platform to view friends' submissions. By creating a lobby on the Litcode website, users can challenge their friends and make interview preparation a more engaging and interactive experience.

To get started, simply install the Litcode extension on Chrome and open Leetcode in your browser. When a question is displayed on the projector, click on the Litcode icon in the top right corner of Chrome (an L icon) and enter your name and the room code provided. It is important to note that Litcode is compatible with the old UI version of Leetcode, so make sure to switch to the old version in your profile settings.

With Litcode, you can use Leetcode as usual, and your submissions will automatically appear on the projector, allowing you to track your progress and compete against your friends in real-time. Make interview preparation more exciting and challenging with Litcode's race against friends feature.
