How to use this tool?

This free online converter lets you convert code from Haskell to Kotlin in a click of a button. To use this converter, take the following steps -

  1. Type or paste your Haskell code in the input box.
  2. Click the convert button.
  3. The resulting Kotlin code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from Haskell to Kotlin using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Example 1 - Is String Palindrome

Program that checks if a string is a palindrome or not.

Key differences between Haskell and Kotlin

CharacteristicHaskellKotlin
SyntaxHaskell has a unique syntax that is based on mathematical notation and is known for its strong type inference.Kotlin has a more familiar syntax that is similar to Java and is known for its conciseness and readability.
ParadigmHaskell is a purely functional programming language that emphasizes immutability and declarative programming.Kotlin is a multi-paradigm language that supports both object-oriented and functional programming.
TypingHaskell has a strong static type system that enforces type safety and allows for type inference.Kotlin has a static type system that supports type inference and also allows for explicit type declarations.
PerformanceHaskell is known for its high performance due to its lazy evaluation and efficient runtime system.Kotlin is designed to be a performant language and can achieve similar performance to Java.
Libraries and frameworksHaskell has a growing ecosystem of libraries and frameworks, but it may not have as many options as more mainstream languages.Kotlin has a wide range of libraries and frameworks available, including many that are compatible with Java.
Community and supportHaskell has a passionate community of developers, but it may not have as large of a user base or as much commercial support as more popular languages.Kotlin has a growing community and is backed by JetBrains, which provides strong support and resources.
Learning curveHaskell has a steep learning curve due to its unique syntax and functional programming concepts.Kotlin has a relatively low learning curve, especially for developers familiar with Java or other similar languages.

Frequently Asked Questions

How do I convert Haskell to Kotlin?

Paste your Haskell code into the input box, confirm the languages are set to Haskell and Kotlin, and click Convert. CodeConvert AI analyzes your Haskell code and generates equivalent Kotlin code in seconds, preserving the original logic and structure.

What are the main differences between Haskell and Kotlin?

Haskell and Kotlin differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Haskell construct to its closest Kotlin equivalent. See the comparison table below for the key differences between Haskell and Kotlin.

Is the converted Kotlin code accurate?

The AI produces high-quality Kotlin code that preserves the behavior of your original Haskell code and follows Kotlin conventions. It handles common patterns, data structures, and idioms for both Haskell and Kotlin. For large or performance-critical code, review and test the Kotlin output before using it in production.

Can I convert an entire Haskell project to Kotlin?

You can convert Haskell files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Haskell to Kotlin. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.

Can I convert Kotlin back to Haskell?

Yes. CodeConvert AI converts in both directions, so you can convert Kotlin to Haskell just as easily using our Kotlin to Haskell converter. Try the Kotlin to Haskell Converter

Is the Haskell to Kotlin converter free, and do I need to install anything?

Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Haskell to Kotlin without an account for up to 5 conversions per day. Sign in for free for higher limits.

What are the benefits of signing in?

Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
