An AI tutor that walks you through LeetCode problems instead of solving them for you
Open any LeetCode problem and Marble follows a structured three-stage routine: understand the problem, build a plan, then implement it. The flow mirrors what interviewers expect to hear in a technical screen.
Help is generated in the language of your choice, so you can keep solving in Python, Java, C++, JavaScript, Go, or whichever stack you interview in.
Marble coaches rather than solves, nudging you toward the right data structure or edge case instead of pasting a finished solution, which reinforces pattern recognition over time.
Activate the tutor from a small pin button directly on the LeetCode problem page, with no separate dashboard or tab juggling.
