Languagelayer is a simple and powerful REST API built to efficiently match text of any length to its corresponding language, cross-referencing single words, expressions, and grammatical constructions, as well as taking into account any existing accents, dialects, and other linguistic deviations.

The Languagelayer API relies on an ever-advancing, powerful and AI-based (Artificial Intelligence) detection algorithm, which increases in complexity and performance with each language detection API request performed. Only this way the languagelayer service can be capable of processing over 170 different languages & accents worldwide.

Despite the complexity behind the scenes, our language detection API continues to stand out thanks to its easy-to-use REST interface, simple JSON response format, quick response times, and low bandwidth consumption.
