Features & Capabilities

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.

Is Free LeetCode TC Analyzer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Free LeetCode TC Analyzer requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Free LeetCode TC Analyzer is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
