langid.py is a standalone language identification tool that classifies text into one of 97 pre-trained languages. It works as a Python library, a command-line tool, and a WSGI-compliant web service in a single file with minimal dependencies.

Use cases

• detect the language of a piece of text
• identify what language a document is written in
• classify text language from the command line
• serve language detection as a web API
• filter text by language in a data pipeline
• detect language of URLs or piped input

When to choose

• you need fast, pre-trained language ID across many languages (97)
• you want a single-file tool with minimal dependencies (just numpy)
• you need both CLI and library usage
• you want to deploy language detection as a web service

When to avoid

• you need language identification for languages outside the 97 supported
• you need to train a custom model on your own domain data (training tools are Python 2 only)
• you need actively maintained software with recent releases
• you need state-of-the-art accuracy on short or mixed-language text
