conjz

Conjz is a multilingual verb conjugation engine and API designed to generate correctly inflected forms across languages. It targets language learning apps, chatbots, spell-checkers, and NLP tools that require accurate conjugations in real time. The project emphasizes extensibility, supporting a growing set of languages and dialects, and outputs in multiple scripts.

Conjz uses a hybrid approach that combines rule-based morphology for regular forms with data-driven models for irregularities. It provides a REST API and a local library with language packs containing paradigms, lemmas, and exceptions. Users can request conjugations by lemma, language, tense, mood, voice, person, and number, receiving either a full set of forms or a single target form. Outputs support multiple scripts and orthographies.

Data and licensing. The project aggregates data from public grammars, open lexical resources, and community contributions. The core engine is open source, with language packs released under compatible licenses; where data licenses apply, those terms govern use. The default software license is MIT.

History. Conjz began as a volunteer project in the late 2010s, with its first public release in 2018. It has grown through community-maintained language packs and updates to expand language coverage and accuracy.

Reception and use. Developers cite Conjz as a practical tool for multilingual applications; researchers note ongoing challenges in morphologically rich languages. The project maintains an open issue tracker and invites contributions from linguists and developers.
