Would you use a service that automatically identifies refactoring opportunities in your code?

Hey,

I’m exploring the idea of a webpage where you can paste a function (or a block of code) in any programming language, and it outputs a list of specific, actionable refactoring suggestions - things like:

• Unnecessary complexity
• Poor naming conventions
• Duplicated logic
• Violations of language-specific best practices
• Readability issues

The goal is to help developers quickly spot areas for improvement and make their code cleaner, more maintainable, and easier to understand.

Questions for you:

• Would you use such a tool? Why or why not?
• What features would make it important for you? (e.g., integration with GitHub, support for obscure languages, explanations for each suggestion, etc.)
• Are you ready to pay for a tool like this (for example, paying for access to advanced checks or being able to tune checks for your programming style)?
• Are there existing tools you love (or hate) that do something similar?
