TimeComplexity.ai
Freemium · $5/moPaste code and get its Big O runtime complexity
What is TimeComplexity.ai?
TimeComplexity.ai analyzes a code snippet and returns its runtime complexity in Big O notation, with reasoning. It handles many languages, including Python, C++, Java, JavaScript and Go, and also works with pseudocode or partial code. Students and engineers preparing for interviews are the main users.
You paste code into a box, or load one of the examples such as binary search, merge sort or three sum, and the tool reports its complexity. A history view shows past queries, and you can delete them.
A paid subscription gives unlimited queries and saved history, which implies the free use is limited. The result is a model's estimate, so check it for tricky algorithms.
