Description
Copy every problem from a LeetCode problem list, tag, company, or study plan into one of your own custom lists. Build your own LeetCode practice list in seconds instead of adding problems one at a time. LeetCode List Cloner reads any list of problems on LeetCode and copies every problem in it into one of your custom lists. Point it at a curated list such as Blind 75, a topic tag, a company's tagged questions, or an official study plan, then choose a target list and click once. WHAT IT CAN COPY • Problem lists — any public list or one of your own, e.g. leetcode.com/problem-list/oizxjoit/ • Topic tags — every problem under a tag, e.g. leetcode.com/tag/two-pointers/ • Company lists — a company's tagged questions, with a picker for the time window (30 days, 3 months, 6 months, more than 6 months, or all). Company data requires LeetCode Premium on your account, as it does on the site itself. • Study plans — e.g. leetcode.com/studyplan/leetcode-75/ HOW IT WORKS 1. Open any leetcode.com tab while signed in. 2. Click the extension icon. If the current tab is already a list, tag, company, or study plan page, the source link is filled in for you. 3. The popup shows the list name and how many problems it contains before you commit to anything. 4. Pick one of your existing lists, or type a name to create a new one. New lists can be created private. 5. Click Clone problems and watch the progress bar. DESIGNED TO BE SAFE TO RE-RUN • Problems already in the target list are skipped, so running the same clone twice does not create duplicates. • Nothing is ever removed from a list. The extension only adds. • Problems are added in small batches with pauses in between to stay gentle on LeetCode's servers. • If one problem cannot be added, it is reported by name in the summary and the rest still go through. • Closing the popup does not cancel a clone in progress. Reopen it to see where the job got to. PRIVACY Everything happens inside your browser, using the LeetCode session you are already signed in with. The extension has no server of its own, sends nothing to any third party, and stores no analytics. It only runs on leetcode.com. NOTES • You need to be signed in to LeetCode. The popup tells you if you are not. • Company lists and some individual problems are Premium-only on LeetCode. Without Premium, the extension reports the same access error the site would. • Very large sources, such as a tag with a few thousand problems, take a few minutes to finish. • This extension is not affiliated with, endorsed by, or sponsored by LeetCode. It uses the same web API your browser already calls when you use the site.
