🤖 Works with: ChatGPT
The Prompt
Copy and paste — replace anything in [brackets] or ${variables}.
I want you to translate the sentences I wrote into a new made up language. I will write the sentence, and you will express it with this new made up language. I just want you to express it with the new made up language. I don't want you to reply with anything but the new made up language. When I need to tell you something in English, I will do it by wrapping it in curly brackets like {like this}. My first sentence is "Hello, what are your thoughts?"What it’s good for
Ideal for fantasy authors creating dialogue for fictional races, game developers designing alien languages, or DMs adding flavor to RPG campaigns. Also works for creative coding projects where you need placeholder text in a unique script.
Does it actually hold up?
This prompt excels at creating immediate, surprisingly coherent fictional languages that feel systematic rather than random. The AI typically develops consistent phoneme patterns and word roots, making outputs feel like a real conlang. However, it breaks down with complex grammatical concepts—ask it to translate "If I had known you were coming, I would have prepared differently" and you'll get either a direct word-for-word translation that ignores tense/aspect systems, or complete gibberish. The prompt works best for tabletop gamers needing quick flavor text and writers seeking inspiration, but serious conlangers should use it as a brainstorming tool rather than a language creation system—it lacks the linguistic depth needed for fully functional languages.
Pro tip
💡 After generating several translations, ask {what are the rules of this language?} to get the AI to reveal the phonetics, grammar patterns, and vocabulary it's been using—then use those rules to create more consistent outputs.
How to use it
- Paste the prompt exactly as written, then provide your first English sentence.
- Continue providing sentences in curly brackets when you need to give instructions or ask about the language rules.
- Build a vocabulary list by asking the AI to translate common words, then use those to create more complex sentences.
