Algo Mentor
AI-Powered Algorithm Learning

Understand Algorithms Through Real-World Stories

Stop memorizing LeetCode solutions. Algo Mentor uses AI to explain every problem with everyday scenarios, interactive slideshows, and a coding playground with a personal mentor — so you truly understand and never forget.

How It Works

From pasting a problem to mastering the concept — in four steps

1

Paste a LeetCode Problem

Drop any LeetCode URL and we'll fetch the problem instantly.

2

Learn Through Stories

AI generates real-world scenarios, visual walkthroughs, and interactive slideshows that make the algorithm click.

3

Practice in the Playground

Write your solution with an AI mentor by your side — pattern tips, progressive hints, and instant test feedback.

4

Never Forget

The scenario-based approach creates lasting memory. Recognize patterns across problems and solve new ones on your own.

AI-Powered Explanations

Every problem gets a comprehensive breakdown designed to make the concept stick

Simplified Explanations

Complex problems explained in plain language a high school student could understand. No jargon, no confusion.

Real-World Scenarios

3-5 vivid everyday analogies that map directly to the algorithm. From cooking to shopping — you'll never forget the concept.

Visual Walkthroughs

Step-by-step ASCII visualizations showing exactly how the algorithm processes data — arrays, pointers, and state changes at each step.

Pattern Recognition

Identify which algorithm pattern applies and why. Build intuition for recognizing similar problems in the future.

Interactive Learning

Visual Slideshows for Every Scenario

Click any real-world scenario to generate a full visual presentation — complete with code, complexity analysis, and approach comparisons

Interactive Slideshows

Click any scenario to generate a beautiful slideshow that walks through the problem using that story — with code examples, complexity breakdown, and approach comparisons.

Beginner-Friendly Complexity

Time and space complexity explained from scratch. What O(n) means in plain English, how it scales with real numbers, and why it matters — all through the scenario.

Compare All Approaches

See brute force, optimal, and alternative solutions side by side with full code, pros/cons, and tradeoffs. Switch between tabs to compare.

Practice Mode

Interactive Coding Playground

A fullscreen IDE with an AI mentor by your side. Write code, run tests, get feedback — all with the scenario guiding you

Code Editor with Autocomplete

Full CodeMirror editor with JavaScript and Python support. Smart autocomplete knows common algorithm patterns — Map, Set, sort, two pointers, and more.

Run Tests Instantly

AI-generated test cases including edge cases. Run your code in the browser — see pass/fail results, console output, and error explanations instantly.

Pseudocode Guide

Before writing code, reveal step-by-step pseudocode tied to the scenario. Each step progressively guides you without giving away the answer.

Debug My Code

AI reads your code, highlights the exact lines with issues, and explains what's wrong using the scenario. Click 'Apply All Fixes' to see the corrected version with a diff view.

AI Mentor Chat

A patient mentor who knows your problem, your scenario, and your code. Ask anything — it guides you with questions instead of giving answers. Select any code for inline chat.

Solution Walkthrough

After solving (or giving up), see the optimal solution with line-by-line annotations tied to the scenario, plus time and space complexity.

To Get Started

Learn the Way Your Brain Remembers

Traditional LeetCode studying means staring at abstract code until it maybe makes sense. Algo Mentor flips the script — every algorithm is taught through a vivid real-world story. When you think "Two Sum," you'll remember Alice searching through bags at the market, not a dry array traversal.

Plain English Real Scenarios Progressive Hints
The Recipe Book

"Alice is a chef who needs to find two bags of ingredients that together weigh exactly the right amount for her recipe..."

Just as Alice searches through her bags, the algorithm searches through the array to find the pair that adds up to the target.

Your Personal AI Mentor

Stuck on a problem? Your mentor knows the problem, the scenario, and your code. Ask anything — "Why isn't my code working?", "What data structure should I use?" — and get a warm, patient response that guides you without giving away the answer. Select any line of code and ask about it inline.

Conversational Code-Aware Inline Debugging
Why is my code returning null instead of the indices?
Think about the order of operations in your loop. Alice is writing down each bag before checking if its match exists. What if she checked first, then wrote it down?
