How It Works
- 1. Phonology — choose how your language sounds: naturalistic, alien, harmonic, or industrial.
- 2. Morphology — decide how words are built: agglutinative, isolating, or fusional.
- 3. Lexicon — pick the vocabulary domain: nature, emotion, or technology.
- 4. Semantics — shape how meaning works: literal, metaphorical, or contextual.
- 5. Pragmatics — define social register: inclusive, formal, or emphatic.

Frequently Asked Questions
- How do I build my own language?
- Start with phonology (sounds), then move to morphology (word structure), lexicon (vocabulary), semantics (meaning), and pragmatics (social context). CraftLingua guides you through all five steps — no linguistics degree required.
- What is a conlang builder?
- A conlang builder (constructed language builder) is a tool for designing your own language from scratch. CraftLingua applies real linguistic theory — the same frameworks used by Tolkien to create Quenya and the teams behind Klingon and Dothraki — to help you build internally consistent fictional languages.
- Is CraftLingua free?
- Yes. CraftLingua is free to use for your first language with no credit card required. Linguist ($9/mo) and Archmage ($19/mo) plans unlock additional language slots, premium Grimoire exports, and other advanced features.
- Can I create a language for Dungeons & Dragons?
- Absolutely. CraftLingua is purpose-built for tabletop RPG campaigns. Design a complete D&D language with its own sounds, word structure, vocabulary, and even hear it spoken aloud in the Auditorium — then share it with your players via a share code.
- What makes CraftLingua different from other language generators?
- Most language generators produce random word-lists with no internal structure. CraftLingua builds real linguistic systems — phonological inventories, morphological paradigms, and lexical domains — that hold together as a coherent, translatable language. It's the difference between a costume and a culture.
- Can I export or share my constructed language?
- Yes. Export your full language as a Grimoire document, typeset and download it as a PNG from the Scriptorium, derive a letter-substitution cipher from your language in the Cryptomancium, share it via URL-safe share codes, or listen to it spoken aloud in the Auditorium.
- Can I use CraftLingua as a cipher or secret code?
- Yes! CraftLingua's translation engine lets you encode any English phrase into your invented language. Share your language via a URL-safe share code so recipients can decode messages — perfect for puzzles, ARGs, escape rooms, and immersive storytelling.
- How do I translate a phrase into my language?
- After completing the five-step wizard, the real-time translation panel lets you type any English word, sentence, or phrase and instantly see it in your constructed language. You can also typeset and export translations as styled images in the Scriptorium.
- Is CraftLingua useful for fiction authors?
- Absolutely. CraftLingua is an author tool built for novelists, screenwriters, and world-builders. Design a linguistically coherent language for your fictional world, export a Grimoire reference document, typeset in-world text, and even hear your language spoken aloud.
