A precise German vocabulary checker and conditional translator that returns exactly one sentence as requested: the translated sentence when German words are detected, or the original sentence when none are present. Designed for reliability, minimal output, and straightforward integration into review and editing workflows. Key benefits Eliminates ambiguity: you receive a single, deterministic result so downstream processes or human reviewers can proceed without manual decision steps. Saves time: automatic detection and conditional translation remove the need for manual scanning of sentences for German vocabulary. Reduces noise: strict output rules prevent extra commentary, metadata, or formatting from contaminating results. Core functions and attributes Function: Scans a provided sentence or short text for German words and returns either the translated sentence (when German words are present) or the original sentence (when no German words are detected). Output behavior: Produces only the sentence specified by the rule above; no additional explanations, markers, or annotations are added. Compatibility: Accepts plain text input (single sentences or short passages) and can be used in manual workflows, scripts, or toolchains that handle text processing. Performance: Deterministic detection and immediate output designed for fast, repeatable use; optimized for clarity and minimal output size. Size and format: Works with standard UTF-8 text input and outputs a single ASCII-compatible sentence as required by downstream systems. Practical use scenarios Multilingual proofreading: Run each sentence through the checker to automatically translate any embedded German words while leaving wholly non-German sentences untouched, streamlining review for editors. Chat or messaging moderation: Integrate into a messaging pipeline to ensure messages containing German vocabulary are normalized via translation, while other messages pass through unchanged. Data preparation for NLP: Preprocess sentence-level corpora by conditionally translating German content to maintain consistent language representation without altering sentences that contain no German. Why choose this tool Predictable and strict behavior prevents unexpected outputs. Minimal, single-sentence output fits automated pipelines and human workflows. Clear specification: it only translates when German vocabulary is found and otherwise returns the original sentence, exactly as instructed.
