CafeTran Espresso vs Supervertaler Workbench

CafeTran Espresso is a computer-assisted translation tool built for translators, with document translation, translation memory and glossary tools. It runs on Windows, macOS and Linux. The product lists AI and machine-translation integration, smart autocompletion, one-click placement of suggested text and a customizable interface. It supports office and publishing formats as well as bilingual formats such as XLIFF, SDLXLIFF, SDLPPX, MQXLIFF and TXML. The maker says translators can accept jobs from clients using SDL Trados, MemoQ, Wordfast and other major CAT tools. The standard version can serve as a translation-memory server for team collaboration, and the system clipboard can support work with PDFs and other difficult formats. The free version runs indefinitely but is limited to 1,000 translation units and 500 glossary terms. The Annual Subscription costs €80 a year and removes those size limits for the subscription year, with updates and full support while current. A One-time Purchase is listed at €200 a month and includes four years of upgrades and support.

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.
