Hi HN,<p>I’ve built Skilltrick, a browser extension designed to help people pass online technical tests, QCMs, and coding challenges on platforms like Leetcode, CoderPad, CodinGame, HackerRank, TestGorilla, and others.<p>The extension works by analyzing the content of the test page in real-time, then offering contextual suggestions or guidance — either via LLM-powered responses or custom hints.<p>It’s particularly useful for:<p>Developers preparing for technical interviews<p>Career switchers taking online assessments<p>Students practicing for exams or certifications<p>Skilltrick was born out of a very personal experience. A few months ago, I had to shut down my company following a serious surgery that nearly cost me the use of my legs. During my recovery, I started job hunting again — and I was shocked at how dehumanizing and mechanical the recruitment process had become, especially with platforms like CoderPad or Leetcode.<p>So I decided to build something that would make this phase more bearable, a tool to help understand questions faster, reduce pressure, and give candidates a fairer shot without grinding endless edge-case algorithms.<p><a href="https://skilltrick.ai" rel="nofollow">https://skilltrick.ai</a>
Currently works best with CoderPad and Leetcode.<p>Still improving it — feedback, criticism, or interesting test cases are all welcome.<p>Happy to answer any questions or share details on the tech stack (Svelte + browser APIs + LLM + DOM parsing engine).<p>Thanks!
