Examples
The following are examples of code conversion from F# 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 F# and Kotlin
| Characteristic | F# | Kotlin |
|---|---|---|
| Syntax | F# has a functional-first syntax with support for imperative and object-oriented programming. | Kotlin has a modern and concise syntax that combines object-oriented and functional programming. |
| Paradigm | F# supports functional programming as its primary paradigm, but also allows imperative and object-oriented programming. | Kotlin is a statically-typed programming language that supports both object-oriented and functional programming paradigms. |
| Typing | F# is a statically-typed language with type inference, which allows for concise code without explicit type annotations. | Kotlin is a statically-typed language with type inference, which helps reduce boilerplate code and provides safety at compile-time. |
| Performance | F# is known for its performance and can be used for high-performance computing tasks. | Kotlin is designed to be a performant language, but it may not be as optimized for high-performance computing tasks as F#. |
| Libraries and frameworks | F# has a growing ecosystem of libraries and frameworks, including support for web development, data science, and more. | Kotlin has a rich ecosystem of libraries and frameworks, with strong support for Android development and web development. |
| Community and support | F# has an active and supportive community, with resources and forums available for developers. | Kotlin has a growing community and is backed by JetBrains, which provides strong support and resources for developers. |
| Learning curve | F# has a moderate learning curve, especially for developers familiar with functional programming concepts. | Kotlin has a relatively easy learning curve, especially for developers familiar with Java or other object-oriented languages. |
Frequently Asked Questions
How do I convert F# to Kotlin?
Paste your F# code into the input box, confirm the languages are set to F# and Kotlin, and click Convert. CodeConvert AI analyzes your F# code and generates equivalent Kotlin code in seconds, preserving the original logic and structure.
What are the main differences between F# and Kotlin?
F# 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 F# construct to its closest Kotlin equivalent. See the comparison table below for the key differences between F# and Kotlin.
Is the converted Kotlin code accurate?
The AI produces high-quality Kotlin code that preserves the behavior of your original F# code and follows Kotlin conventions. It handles common patterns, data structures, and idioms for both F# and Kotlin. For large or performance-critical code, review and test the Kotlin output before using it in production.
Can I convert an entire F# project to Kotlin?
You can convert F# 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 F# 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 F#?
Yes. CodeConvert AI converts in both directions, so you can convert Kotlin to F# just as easily using our Kotlin to F# converter. Try the Kotlin to F# Converter
Is the F# 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 F# 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.
