The most accurate natural language detection library for Go, excelling with short text and mixed-language content.
Lingua is a natural language detection library for the Go programming language. It identifies the language of a given text, solving the problem of accurately determining language from short or mixed-language content where other libraries often fail. It's designed as a lightweight, offline alternative to larger NLP frameworks for this specific task.
Go developers building natural language processing applications, text analysis tools, or systems that require language identification as a preprocessing step, such as for content filtering, routing, or localization.
Developers choose Lingua for its superior accuracy on short text and mixed-language content compared to alternatives like Whatlanggo and CLD3, its offline capability, and its simplicity as a focused library without the overhead of full NLP frameworks.

Lingua consistently outperforms competitors like Whatlanggo and CLD3 on single words and phrases, as shown in accuracy plots where it achieves higher scores for languages like English (55% vs 17% for single words).
Supports 75 languages from Afrikaans to Zulu with a quality-over-quantity approach, ensuring reliable detection for common and less common languages, as listed in the README.
Works completely offline without external APIs, making it ideal for privacy-focused applications or environments with limited connectivity, as emphasized in the library's philosophy.
Effectively detects text containing multiple languages, a highlighted feature that addresses shortcomings in other libraries like Whatlanggo.
Detection accuracy varies significantly; for example, Bosnian has only 35% accuracy in high-accuracy mode, much lower than languages like Chinese or Greek, as shown in the detailed statistics table.
High-accuracy mode may be slower and more resource-intensive, which could impact latency-sensitive applications, though a low-accuracy mode is offered for faster operation.
As a focused library, it lacks broader natural language processing capabilities, requiring integration with other tools for tasks like translation or syntax analysis, which might add complexity.
