An AI mentor that coaches, not spoils, your LeetCode practice
The assistant asks focused questions that push your thinking forward instead of revealing the solution.
Receive graduated hints that nudge you toward the insight without spoiling the exercise.
It adjusts to your skill level and learning pace, so guidance fits a beginner or a seasoned candidate.
Get plain-language explanations of core computer-science concepts, data structures and algorithms as you need them.

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.
