Desktop and mobile AI copilot that feeds live answers during coding and system design interviews
The desktop app is designed to remain hidden from Zoom and browser-based screen recording, with moveable overlays and no visible taskbar presence.
Capture any window containing a coding problem and receive a complete solution with syntax highlighting, approach notes and complexity analysis.
Transcribes both your voice and the interviewer's audio so spoken system design and behavioral questions can be answered in the moment.
Pair the desktop app with a phone for remote screenshots, prompts and answers, or use the browser-based mobile mode with no installation.

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.
