LeetBlur: Blur & Redo LeetCode Solutions

Blur your saved LeetCode solution so you can redo the problem spoiler-free. Peek or reset to a clean slate in one click.

Reopening a LeetCode problem you've already solved? LeetCode auto-restores your old code, which spoils the whole point of practicing again. LeetBlur fixes that. It blurs your previously saved solution behind a frosted overlay the moment the problem loads, and adds two small buttons to the code pane: - Look: reveal your old solution when you're ready to check it. It stays revealed until you open a different problem. - Clear: wipe your old code and reset the editor to LeetCode's starter stub for the current language, so you can redo the problem from a clean slate. The blur only appears when there's an actual solution to hide. A brand-new, template-only editor is left alone, so a fresh problem is never touched. You're always in control: a toolbar button lets you turn blurring on or off at any time, and your choice is remembered. Private by design: everything runs locally in your browser. No account, no tracking, no analytics, and no data ever sent to us (we have no servers). The only network request goes to LeetCode's own public API, without your cookies, to fetch the problem's starter template. Works on https://leetcode.com problem pages.
