Turn LeetCode grind into real interview prep.

Practice coding interviews in two modes: a friendly mentor that teaches you every step, and a strict AI interviewer that simulates real pressure. Track your roadmap, code in-browser, and let AI grade your solutions.

No setup required. Your progress saves when you sign in.

Roadmap mode

Structured categories and difficulties. Learn problems with an AI mentor beside your editor.

Interview mode

Timed, conversational interviews. AI asks follow-ups and evaluates your code like a real interviewer.

Progress tracking

Mark problems complete, see completion bars per topic, and focus on your weak spots.

Hey! I'll be your interviewer today. Ready to tackle a Medium array problem?

Yes, let's start.

Great. Implement twoSum. Talk me through your approach as you code.

Editor

function twoSum(nums, target) {
  // 1. Use a map to track complements
  // 2. Return indices when we find a match
}

Built to feel like a real interview, not a problem list.

Conversational AI mentor

Ask follow-up questions, get hints, and have concepts explained in plain language as you work through problems.

In-browser coding environment

Code in a Monaco-powered editor side-by-side with the chat. No context switching, no extra setup.

Honest feedback & completion tracking

Get specific feedback on correctness and complexity, and mark problems complete across categories and difficulties.

Two modes. One goal: perform better in real interviews.

Roadmap mode

Learn systematically with an AI mentor

Pick a problem from a curated roadmap. The AI explains patterns, guides your thinking, and helps you build intuition instead of just memorizing solutions.

• Topic-based categories and difficulty levels
• Boilerplate code generated for each problem
• Completion bars to see your progress at a glance

Interview mode

Simulate the real thing with an AI interviewer

The AI asks questions, probes your reasoning, and evaluates your solutions. You'll practice talking through your approach while you code—just like onsite.

• Realistic interviewer-style prompts and follow-ups
• Feedback on correctness, time & space complexity
• Mark problems complete directly from interview results

From zero to ready in three steps.

1. Pick a mode

Start in roadmap mode to learn patterns, then switch to interview mode once you're comfortable.

2. Solve with AI in the loop

Code directly in the editor while the AI explains, questions, and critiques your work.

3. Track your progress

Watch your completion bars fill up across topics and difficulties as you pass more interviews.
