Frequently asked questions

What is an AI code-explanation tool?

An AI code-explanation tool uses machine learning models to analyze source code and translate its underlying logic into plain human language, helping developers understand unfamiliar scripts or legacy projects.

Are these tools safe to use with proprietary code?

Many tools offer enterprise privacy guarantees, ensuring that your code is not used for model training and is processed securely. However, free public tiers may retain user inputs, so checking individual privacy policies is essential.

Do I need coding experience to use them?

While these tools make code much easier to interpret, a basic understanding of software development principles is still helpful to verify the accuracy of the AI explanations.
