Recently, I tried LeetCoding on my phone while heading back home. The experience was worse than expected because of frequent typos. Hence, I built a browser extension that allows you to write your solutions in English instead. It will automatically convert your logic into Python 3 syntax and paste it into LeetCode’s code editor.

To assist with debugging, the extension has a separate “Test” button. This feature evaluates your current code snippet. If erroneous logic is identified, it generates and adds a single test case.

The extension is free as it uses my personal OpenAI API key, which is stored on Vercel. If you would like the OpenAI call to run directly from your browser, you can pass in your own OpenAI API key.

Finally, to use the browser extension on mobile, you have to use Microsoft Edge. Google Chrome does not support extensions on mobile.

Hope this helps someone!
