AutoTrans

AutoTrans is a lightweight, high-control translation automation solution built in C# for Windows. Its primary strength lies in its asynchronous architecture, which offloads all potentially long-running operations — including batching, API requests, retries, and validation — to background tasks. This design guarantees a responsive and stable user interface, even during extensive translation runs.

The utility places strong emphasis on correctness through its advanced exclusion engine. Before any text is sent to the DeepL API, it is evaluated against a configurable set of rules that prevent non-translatable or unwanted content from being processed. These rules include empty or whitespace-only strings, single characters, numeric and percentage values, punctuation-only strings, exact token matches, and user-defined regular expressions. Exclusion settings can be applied globally or per project, ensuring consistent behavior across different workflows.

Operational reliability is further reinforced through controlled batching and resilient API communication. AutoTrans applies request pacing and retry logic with exponential backoff to handle rate limits and transient network errors gracefully. Progress reporting remains accurate throughout the process by reflecting only valid translation units, avoiding misleading status updates.

From an architectural standpoint, AutoTrans enforces a clear separation of concerns. The core translation engine is solely responsible for execution and validation, while the UI layer handles user interaction, progress display, and error reporting. Secure licensing and activation are integrated using protected storage and hardware-bound validation, ensuring safe and reliable usage without exposing sensitive data.

Overall, AutoTrans is designed not as a simple “one-click translator,” but as a professional translation automation tool for developers and localization teams who require precision, stability, and full control over their translation pipelines.
