Déjà Vu X3 review
A feature-rich Windows CAT tool for translators and teams that need deep QA and alignment.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Déjà Vu X3 is a Windows-based computer-assisted translation tool for freelance translators, translation teams, agencies and language service providers. Its core workspace combines translation memory creation and maintenance, termbase administration, alignment, multilingual and multi-format projects, terminology checks, customizable quality assurance and automatic export. Professional is aimed at individual translators, while Workgroup adds shared translation memories and termbases, collaboration and workload splitting, and unlimited target languages.
The freemium structure gives buyers a way to start with Déjà Vu X3 Free at €0 one time. That edition supports standalone projects and satellite projects prepared with Workgroup. Paid access starts at €420 one time, with Professional adding DeepMiner, AutoWrite, translation-memory tools and termbase administration. Workgroup adds team features, with separate five-, 10-, 20- and 50-license bundles. The published plan structure suits buyers comparing a free entry point with permanent-license options rather than recurring billing.
Its strongest fit is for Windows users who need more than basic translation memory. DeepMiner can repair fuzzy matches and assemble subsegments, while AutoWrite provides predictive suggestions from translation databases. Alignment supports single-file and multi-file, multi-format projects, and QA can be customized for terminology and batch checks. The software also connects with Google Translate, Microsoft Translate, Itranslate4, MyMemory Translate, Systran, Promt Translation and other providers, and supports formats including XLIFF, TMX, termbases and RTF. Choose Déjà Vu X3 for advanced desktop QA, alignment and memory management; buyers needing non-Windows deployment should consider another tool.
