with intention

A complete toolkit for designing constructed languages. From phoneme inventories to syntax rules, create languages that feel authentic and internally consistent.

What you can build

Every component of a language, systematically organized.

01

Phonology

Define consonants, vowels, and suprasegmentals. Set up allophonic rules, phonotactic constraints, and syllable structures.

02

Morphology

Create grammatical categories like case, number, and tense. Define morphemes, affixes, and inflection paradigms.

03

Syntax

Establish word order rules, phrase structures, and transformations. Document how sentences are constructed.

04

Lexicon

Build your vocabulary with definitions, etymology, semantic fields, and relationships between words.

05

Writing Systems

Design scripts from alphabets to logographies. Define glyphs, romanization rules, and rendering options.

06

Texts

Write and translate texts with interlinear glossing. Build a corpus that demonstrates your language.
