AI-Assisted Problem Solving
is the Future. We are building it with Trace.
Trace lives inside LeetCode as a Chrome extension, in your browser as a web dashboard, and in long-form thinking as AI Notebooks. Everywhere you code — Trace asks the right question.
Every day, tens of millions leave LeetCode. Minutes later, they open ChatGPT.
Not to get the solution. But to understand it. That's exactly why we built Trace.
- Reads your code, test cases, and the error — together
- Asks the right question. Never just hands you the answer
- Built natively inside LeetCode — not a generic AI wrapper
- Session memory — Trace learns your patterns over time
