An invisible AI copilot that solves coding interview problems in seconds
The model inspects the problem and returns several viable algorithms sorted from worst to best time complexity, including for problems that are not published anywhere.
Pick an algorithm and receive idiomatic code for your chosen language, edge-case tests and a written complexity analysis within seconds.
Undetectable global hotkeys run at a privileged level, and the window is designed to stay invisible in screenshots and screen-sharing software.
Mirror every output to a phone, tablet or second laptop so you never need to open anything on the machine being proctored.

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.
