Leetcode Explained is a Chrome add-on developed by zjdevelops. It offers a comprehensive solution guide and code analysis for Leetcode problems. This free add-on is a valuable resource for programmers looking to enhance their problem-solving skills.

The main features of Leetcode Explained include video solutions, code solutions in multiple programming languages (Python, Java, C++, and Javascript), access to company tags, Elo ratings for contest problems, complexity analysis, code generation, and a hard mode that simulates a real interview environment. The add-on also provides a tutorial for easy navigation and usage.

In the latest versionupdate, company tags and problem frequency have been removed due to copyright and premium user privileges. However, the developer welcomes access to public datasets detailing company frequency for future improvements.

Leetcode Explained prioritizes user privacy, ensuring that no data tracking occurs. All data remains local in the user's browser, and no API key is required for GPT functionalities.

For those interested in contributing to the project, the source code is available on GitHub at github.com/zubyj/leetcode-explained.
