The Chrome extension

Install Branch for LeetCode from the Chrome Web Store and connect it in Settings. When LeetCode accepts one of your submissions, it's marked solved in Branch, once, with no clicking.

• Your code is kept privately on your Solutions tab, and you can delete it any time.
• The extension only watches your own submissions' results; it never changes LeetCode's pages or asks it for anything.
• Marking problems solved by hand still works.
