## Overview

Marble is a lightweight Chrome extension for people grinding LeetCode who want to learn the reasoning behind solutions rather than simply copy them. It injects a small circular pin onto the LeetCode problem page; clicking it opens an AI tutor that walks you through the problem interactively. The approach is deliberately Socratic: the tutor helps you break down the prompt, propose an approach, and translate that plan into working code.

## Pricing & Plans

Free browser extension. No subscription or paid tiers are advertised on the Chrome Web Store listing.

## Key Features & Capabilities

- **Guided walkthroughs on any problem:** 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.
- **Works across languages:** 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.
- **Builds interview thinking, not answers:** 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.
- **Lightweight in-page extension:** Activate the tutor from a small pin button directly on the LeetCode problem page, with no separate dashboard or tab juggling.

## Primary Use Cases

- **Practice interview-style problem solving (Interview candidate):** Use the guided walkthrough to practice narrating your approach out loud, mirroring how you would explain a solution to an interviewer.
- **Learn data-structure patterns (Student or self-learner):** When a problem's optimal approach is unclear, let the tutor help you reason through the prompt and edge cases before you reach for a known solution.
- **Reinforce fundamentals between projects (Developer upskilling):** Turn a solved question into a learning exercise by working the plan and implementation stages interactively rather than reading a discussion post.

- Free to install and use directly in the browser
- High user rating (5.0 across 23 ratings at time of review)
- Coaches understanding instead of handing over solutions
