ApSIC Xbench vs Supervertaler Workbench

ApSIC Xbench combines translation quality assurance with terminology management for professional translators. It searches bilingual reference files and terminology sources in common CAT formats, including TMX, XLIFF, Trados, Wordfast, memoQ, and Deja Vu. Built-in checks cover completeness, consistency, numbers, tags, spelling, and key terminology; users can also make checklists using PowerSearch, regular expressions, or Microsoft Word wildcards. Hunspell dictionaries support spell-checking in 48 languages. Plugins or extensions are listed for Trados Studio, Passolo, Matecat, Phrase TMS, Transifex, Smartcat, Crowdin, and Google Polyglot. Xbench 3.0 is available for Windows in 32-bit and 64-bit editions, with support listed from Windows XP through Windows 11. Its fully functional trial lasts 30 days. Xbench 3.0 costs €99/year + VAT (if applicable). Xbench 2.9 is free, but is non-Unicode and its development is frozen. Licensed users can install Xbench on internet-connected computers, with one simultaneous instance per authorized user.

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.
