One real example
An actual slide from my CS 340 lectures, and the Lab Kodo generated from it.
Not generic interview prep. Built from what your course actually teaches.

Pointers and Arrays
- •An array name is essentially a pointer to its first element
- •arr[i] and *(ptr + i) access the same memory
- •Pointer arithmetic scales by the size of the pointed-to type
- •No bounds checking at compile-time or run-time
A ready-to-solve Lab comes out

Problems
Array Indexing with Pointers
easyRead an integer n, then n values into an array. Walk the array using pointer arithmetic only (no [] indexing) and print their total as Sum: <total>.
LeetCode
Hands you generic pointer puzzles and assumes you already know the syntax.
ChatGPT
Writes the whole pointer-arithmetic solution for you. Nothing left to practice.
Kodo
The exact question your lecture just covered, with tests that check your work.
Not a magic wand: you still do the thinking. Kodo just makes sure it goes into the right problems.

The whole flow, upload to code, in under 30 seconds.
How it works
From your slides to coding in three steps.
Drop your slides.
PDF, image, or doc. Kodo reads it and pulls out the concepts your course covers.
Get a Lab.
A set of 3-5 coding problems matched to your lectures, ordered easy to hard, each with its own test cases.
Solve them.
Write your code in the browser and run it against the tests. Nothing to install.
From a real student
“I used it to study for a midsem test I had and it definitely helped me because I learn better through pattern recognition, and being able to actually do practice helped so much more than just reading and understanding syntax.”

Why Kodo exists
Hi, I'm Lucas. I'm a second-year CS student. I bombed a Java midterm after knowing some theory and syntax but having no practice. None of it matched what the course actually tested, so I built Kodo that week. I'm studying with it for my own exams right now.
