The anti-solution DSA coach

    Stop reading solutions.
    Start discovering them.

    Paste any LeetCode problem. Mentora turns it into a 5-step roadmap of smaller sub-problems and layered hints, guiding your intuition without spoiling the answer.

    How it works

    From stuck to structured in one guided session.

    1. Drop a problem

    Paste a LeetCode URL or type the problem name. Mentora identifies the problem and the patterns hiding underneath.

    2. Follow the roadmap

    Work through five smaller sub-problems that build the original idea one piece at a time.

    3. Ask for hints

    Reveal three levels of guidance only when you need them, from concept to approach to pseudocode-level nudge.

    5 guided sub-problems

    Each step builds one piece of the final intuition.

    Restate the goal
    Find the recurrence
    Handle edge cases
    Step 3
    Hint revealed
    Level 1: conceptual

    Start with the recurrence before thinking about optimization.

    No final answer
    Hints unlock gradually
    Progress stays saved

    A mentor, not an oracle.

    Searching the answer feels productive. It isn't. Mentora uses Socratic questioning, smaller analogous problems, and pattern naming, the same way great human coaches teach algorithms.

    • Five sub-problems per question — each solvable on its own
    • Three hint levels you reveal one at a time
    • Pattern tags so you build a mental library, not memorize answers
    Example: Two Sum

    Step 2 — Lookup speed matters

    Given a list of numbers, can you tell in O(1) whether a specific number exists?

    Hint 1: Which data structure offers constant-time membership checks?
    Hint 2 locked until you ask for it
    The practice loop

    A better rhythm for DSA practice.

    Mentora turns each problem into a repeatable loop: understand, attempt, request a nudge, reflect, and move forward.

    Practice with structure

    Every session has a clear next move, so you spend less time wondering what to do and more time actually thinking.

    Revisit weak patterns

    Completed steps and hint usage shape your dashboard, making weak areas easier to notice before they become habits.

    Build durable intuition

    Instead of memorizing final code, you build the smaller mental tools that transfer across similar questions.

    Keep answers earned

    Mentora avoids final solution dumps and keeps the learning focused on discovery, not shortcut collection.

    Learner notes

    Built for people who want the click, not the copy.
