Free LeetCode TC Analyzer par Swan

Free LeetCode Complexity Analyzer is a browser extension that analyzes the time and space complexity of your LeetCode solutions directly inside the LeetCode editor.

The extension extracts your code, problem description, and constraints, then uses an AI-powered analysis engine to:

• Calculate time and space complexity (Big-O notation)
• Break down the cost of individual code sections
• Estimate worst-case performance under maximum constraints
• Detect whether the current approach is optimal
• Compare your solution with the optimal approach
• Provide optimization suggestions and complexity insights

Users can securely connect their own Mistral API key through the built-in settings page. No account registration is required.

Designed for competitive programmers, coding interview preparation, and algorithm learning, the extension helps users understand not just whether a solution works, but how efficiently it works.
