Supervertaler Workbench is a desktop CAT tool that combines AI translation with traditional translation workflows. It supports AI translation, batch translation, chat, prompts, image context, proofreading, and local models through Ollama. Listed providers include OpenAI, Anthropic Claude, Google Gemini, Mistral AI, DeepSeek, OpenRouter, and custom OpenAI-compatible endpoints. Translation tools include fuzzy matching, TMX import, and concordance search; terminology features include termbases, automatic term highlighting, and TermLens. Workbench supports DOCX and TXT, with further formats through Okapi, including IDML, HTML, XLIFF, PO, XLSX, and PPTX. Its documentation describes exchange workflows for memoQ, Trados Studio, Phrase, and CafeTran. Documents, termbases, and translation memories stay on the user's machine. When an AI action is triggered, requests go to the selected provider; Ollama processes them locally. Workbench runs on Linux, macOS, and Windows and supports offline use. It is free and open source under the MIT license. Its maker says development is no longer active, though genuine bugs may still be fixed and releases continue.
