Dehelper

Dehelper is a macOS‑only application that serves as a comprehensive German‑Chinese dictionary and language‑learning tool. It offers a large lexical database with over 350 000 entries, including a German‑Chinese and Chinese‑German dictionary, extensive example sentences, and a picture‑based dictionary covering roughly 40 000 words. The software also provides features such as real‑time pronunciation, verb‑conjugation tables for all 17 German tenses, and a built‑in flash‑card system that follows a spaced‑repetition schedule.

In addition to static dictionary content, Dehelper integrates AI‑driven translation powered by configurable large‑model APIs, allowing users to translate sentences, paragraphs, or entire PDF documents while preserving original formatting. Users can customize translation style prompts, create personal terminology libraries, and edit AI outputs for professional quality. The app supports image‑based word lookup, camera capture of text, and voice input for on‑the‑fly translation.

Learning tools include daily sentences with native narration, a notebook for personal notes, a highlighting system, and cloud‑synchronised vocabularies across multiple platforms. The interface offers dark mode, customizable fonts and colours, and export options for bilingual documents, making it a versatile resource for German learners and translators.
