Frequently asked questions
Which programming languages are supported?
The tool supports most major languages, including Python, JavaScript, TypeScript, Java, C#, C++, Go, PHP, and Ruby.
Will refactoring alter the behavior of my code?
The AI is designed to maintain behavioral equivalence, meaning your inputs and outputs remain unchanged while internal structure, readability, and efficiency improve.
Is the AI code refactoring tool free to use?
Doffl offers a free trial so you can evaluate the refactoring capabilities. Continued access and higher usage limits require an active paid subscription plan.
Is my proprietary code kept private and secure?
Yes. Your code snippets are processed securely through encrypted connections and are not used to train public machine learning models.
Can I refactor an entire codebase at once?
The browser tool is optimized for functions, classes, and single-file modules. For full-project refactoring, review and process files modularly.
