Tools
I build and maintain tools that support real-world translation workflows. Everything here is either open-source or source-available and built with working translators in mind.
Supervertaler
Supervertaler is an AI-enhanced CAT tool ecosystem with two products:
Supervertaler Workbench
Supervertaler Workbench is a free, open-source, cross-platform CAT tool (Windows, Mac, Linux) with multi-LLM translation, translation memory, glossary management, quality benchmarking, and concordance search. Includes two system-wide utilities: QuickLauncher (right-click AI prompt launcher) and QuickTrans (instant multi-engine translation popup). Supports import from memoQ, Trados (SDLXLIFF/SDLPPX), CafeTran, Phrase, and Déjà Vu.
Supervertaler for Trados
Supervertaler for Trados is a Trados Studio plugin bringing inline contextual terminology display (TermLens), an AI chat assistant, batch translation, and a prompt library directly into Trados Studio. Two paid tiers: TermLens (€10/month) for terminology features, and TermLens + Supervertaler Assistant (€15/month) adding AI chat, batch translate, and prompt library. 14-day free trial, no credit card required.
