Undetectable AI coding assistant for technical interviews
AI suggestions appear in a modal only you can see, keeping them out of screen-sharing captures.
Hover-to-click interaction removes visual and audio cues that could give you away during an interview.
Query OpenAI, Google Gemini, or Anthropic Claude directly with your key, paying only for what you use.
The app reads what is on screen and uses that context to produce relevant code, explanations, or solutions.
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.
