AI-Powered

AI Chat Tutor

Get unstuck with an AI tutor that actually understands your code. Ask questions, request hints, or walk through your approach — the AI adapts to your level.

Context-aware: sees your current code and problem
Progressive hints that guide without spoiling
Explains concepts, not just answers
Available everywhere — problems, courses, and guided learning

Context: Two Sum problem

I don't understand why my solution is O(n²). Can you help?

Your nested loop checks every pair. Try using a hash map to store seen values — that gives you O(1) lookups and brings it down to O(n).

Oh! So I replace the inner loop with a dict lookup?

Ask about your code...

AI Guide

Let's implement BFS! Start by creating a queue and a visited set.

Done! What's next?

Now dequeue a node and explore neighbors. I'll push a template:

bfs.py

def bfs(graph, start):

queue = [start]

visited = {start}

while queue:

node = queue.pop(0)

# explore neighbors

Loved by students

Hear from CS students who improved their grades and confidence with WeMentor.

WeMentor completely changed how I prepare for exams. The AI tutor helped me understand recursion in a way my textbook never could.

Maria P.

CS Student, University of Bucharest

The guided learning feature is incredible. I picked "Graph Algorithms" and the AI walked me through BFS, DFS, and Dijkstra step by step with code examples.

Alex T.

Software Engineering Student

I used to dread data structures exams. After two weeks on WeMentor, I went from struggling with trees to solving medium-level problems confidently.

Ioana D.

2nd Year CS Student

The multiple choice questions with progressive hints are genius. They force you to think before giving away the answer. My quiz scores improved dramatically.

Andrei M.

CS Student, Politehnica

Having an AI that can see my code and explain what is wrong is like having a personal tutor available 24/7. Worth every penny.

Elena V.

Graduate Student, Computer Science

The structured courses are perfect for learning new topics. I went through the sorting algorithms course before my exam and it covered everything I needed.

Cristian R.

3rd Year CS Student

Finally a platform that does not just give you problems but actually teaches you how to think about them. The AI hints are perfectly calibrated.

Sofia L.

CS Student, Cluj-Napoca

I recommended WeMentor to my entire study group. We all saw improvements in our algorithm exam scores within the first month.
