LeetOne

Your all-in-one LeetCode extension — real difficulty ratings, YouTube solutions, and a one-click code copy button.

LeetOne supercharges your LeetCode experience with three powerful features: REAL DIFFICULTY RATINGS See actual community difficulty ratings (from zerotrac) alongside LeetCode's Easy/Medium/Hard labels. Know exactly how hard a problem really is before you start. YOUTUBE VIDEO SOLUTIONS Browse embedded YouTube solution videos directly inside LeetCode's Solutions pane — no tab switching needed. Videos are sorted by view count so the most helpful ones appear first. Results are cached for 1 week for instant loading. ONE-CLICK CODE COPY Copy any code block on LeetCode with a single click. No more manual selection. FULLY CUSTOMIZABLE Toggle each feature on or off from the extension popup. Ratings always show. YouTube solutions and the copy button can be enabled or disabled per your preference. LeetOne works automatically on all LeetCode problem pages — just install and start solving. No accounts. No tracking. No ads. Found a bug or have a feature request? Feel free to reach out at rakeshmuntha27@gmail.com or connect with me on LinkedIn - https://www.linkedin.com/in/rakeshmuntha/.
