LeetCo is a Chrome extension designed to enhance the LeetCode experience by providing company-specific insights directly on problem pages. It eliminates the need for LeetCode Premium by offering free access to valuable interview preparation data.
LeetCo automatically detects LeetCode problems and displays company badges with logos showing which companies asked each problem. It provides time-range based insights from recent to all-time data and offers fast API-backed responses. The extension features a beautiful dark, glassmorphism UI and works seamlessly with LeetCode's single-page application navigation.
The extension works through a content script that detects LeetCode problems and extracts problem slugs. These slugs are sent to LeetCo's backend API, which returns company insights that are then injected as UI elements below the problem title on LeetCode pages.
LeetCo helps users prepare smarter for technical interviews by showing company frequency insights and how recently problems were asked. It enables focused preparation without tab switching or distractions, making interview preparation more efficient.
The extension is built specifically for students and developers preparing for technical interviews who want to save money while grinding data structures and algorithms problems.
