MARFA

MARFA is a browser-based CAT tool designed for professional translators, reviewers, and language specialists who work with bilingual texts, translation memories, and terminology-rich documents.

The tool provides an integrated workspace for importing Word, Excel, HTML, TMX, and translation-memory files; building and searching translation memory; analyzing source segments; detecting best matches; reviewing match rates; editing target drafts; running concordance searches; and exporting final outputs.

MARFA helps organize bilingual translation work, improve consistency, reuse previous translations, and reduce repetitive manual effort directly inside the browser.
