LeetCode productivity helper extension

Makes it easier to track progress, practice randomly, and copy problem details/solutions/test cases while using LeetCode.

User installs extension, navigates to leetcode.com. Extension popup shows stats. User can pick a random problem, or copy problem/solution/testcase data to clipboard. Options page allows customizing answer templates.

Target users: LeetCode users / Coding interview preparers

popup.js and options.js are heavily minified React bundles, making it difficult to trace all UI interactions directly. However, content.js logic and store description provide sufficient evidence for the main decisions.

Monetization

No paid features detected

The extension itself is free. The description mentions a 'Premium' toggle to include/exclude premium problems in stats, but this refers to LeetCode's own Premium subscription problems, not a paid feature of the extension. The extension does not gate any of its own features behind a paywall, nor does it call any billing or license APIs. The 'paid_only' keyword found in content.js is used to filter out LeetCode's premium problems from the stats/pick functionality, not to enforce a payment.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension is a helper for LeetCode (leetcode.com). To view problem details, stats, and use features like 'pick problem' or 'copy question', the user must be on leetcode.com pages. While some public stats might be accessible without login, the core workflow of interacting with specific problems, viewing personal progress/stats, and copying solutions requires being logged into a LeetCode account. The extension itself does not implement its own login but relies on the destination service's auth state.
