Supervertaler Workbench vs TextUnited

Supervertaler Workbench is a free standalone CAT tool that combines AI translation with traditional computer-assisted translation workflows. It supports AI translation, batch translation, chat, prompts, image context and AI proofreading, as well as local models through Ollama. Listed providers include OpenAI, Anthropic Claude, Google Gemini, Mistral AI, DeepSeek, OpenRouter, Ollama and custom OpenAI-compatible endpoints. Translation features include fuzzy matching, TMX import and concordance search; terminology tools include termbases, automatic term highlighting and TermLens. DOCX and TXT are supported directly, with additional formats through Okapi, including IDML, HTML, XLIFF, PO, XLSX and PPTX. Documentation describes exchange workflows for memoQ, Trados Studio, Phrase and CafeTran. The privacy policy says documents, termbases and translation memories stay on the user's machine, while AI requests go directly to the selected provider when an AI action is triggered. Ollama processes data locally. Workbench runs on Linux, macOS and Windows and supports offline desktop use. Its maker says it is no longer actively developed, though genuine bugs may still be fixed and releases still go out.
