What is Leetcode Whiteboard?
A Chrome extension that adds a whiteboard to LeetCode problem pages. Built with tldraw to help you draw, write, and visualize algorithms as you solve them.
Problem
Users preparing for technical interviews often use separate tools for coding (LeetCode) and diagramming (external whiteboards), leading to inefficient workflow and context switching.
Solution
A Chrome extension that integrates a whiteboard directly into LeetCode problem pages, enabling users to draw, write, and visualize algorithms in real-time while solving coding challenges (e.g., sketching data structures or flowcharts).
Customers
Software engineers and developers preparing for coding interviews, coding bootcamp students, and competitive programmers seeking an all-in-one practice environment.
Unique Features
Seamless integration with LeetCode's interface using tldraw for real-time whiteboarding without leaving the problem page.
