Introduction

The Language Detector Scraper analyzes multiple lines of text and determines the language of each one individually. It solves the problem of identifying languages in mixed or unknown text sources without manual inspection. This project is ideal for developers, analysts, and product teams working with international or user-generated content.

Why this tool exists

• Processes each line independently for precise language identification
• Uses probabilistic models to provide confidence scores
• Supports multilingual inputs in a single run
• Returns alternative language guesses when ambiguity exists

FAQs

Does this tool work with very short text? It performs best on full sentences or short paragraphs. Extremely short or ambiguous inputs may result in lower confidence scores.

Can it handle mixed languages in one input? Yes. Each line is processed independently, so different languages in the same input are fully supported.

What languages are supported? The model supports a wide range of commonly used languages, especially those with strong n-gram representation.

Is this suitable for real-time processing? Yes. The detection process is lightweight and fast enough for near real-time use in most applications.
