A new tool called ConlangCrafter is revolutionizing how linguists and enthusiasts create constructed languages, blending AI with linguistic creativity.
If you've ever dabbled in creating a constructed language (conlang), you know it's no small feat. From crafting phonetics to defining grammar rules, the process can be both rewarding and daunting. Enter ConlangCrafter, an AI-driven tool that aims to make this task more accessible and efficient. Developed by researchers at the University of California, Berkeley, ConlangCrafter leverages advanced natural language processing (NLP) techniques to assist in generating conlangs.
ConlangCrafter stands out from existing tools by integrating deep learning models with linguistic theory. Here are the key technical advancements:
Let's dive into some of the key features and how they are implemented:
Phonetics Generation:
Grammar Rules:

ConlangCrafter has already found applications in various fields:
As ConlangCrafter continues to evolve, here are some areas to watch:
ConlangCrafter represents a significant step forward in the field of constructed languages, blending advanced AI with linguistic expertise. Whether you're a linguist, educator, or creative writer, this tool offers exciting possibilities for exploring and creating new languages.

About the author
Kai built ML infrastructure at a Bay Area startup before developing an obsession with transformer architectures and inference optimisation that eventually pulled him out of product work entirely. A stint at a compute research lab sharpened his instinct for what actually matters in a model release versus what is marketing. He writes from the inside — from the perspective of someone who has debugged the systems he is describing at three in the morning. He is allergic to hype and instinctively drawn to the unglamorous plumbing questions that everyone else skips over.
