Lingua is a language detection library for Python (with a Rust core) that identifies which of 75 languages a text is written in. It is designed for high accuracy on short and mixed-language text, using rule-based and statistical Naive Bayes methods entirely offline.

Use cases

• detect the language of a short text snippet like a tweet
• identify language of single words or phrases
• preprocess text for language-specific NLP pipelines
• route customer emails by language
• detect language in mixed-language text
• run language detection offline without external APIs

When to choose

• you need accurate detection on very short text where CLD3 or langid fail
• you need offline detection without network calls
• you need support for many languages with mixed-language input

When to avoid

• you need neural-network-based detection or embeddings
• you work with Python < 3.12
• you need extremely lightweight detection of only a few major languages
