For professional translators

A CAT tool, native to the Mac. LinguaTrans.

Open bilingual files from Trados, memoQ, Phrase or Wordfast, work through them keyboard-first, and hand them back intact — no broken tags, no reformatting. No Java runtime, no Windows VM, no Electron shell.

LinguaTrans bilingual editor with source and target columns and the filter sidebar — Editor, TM, Glossary, QA — a two-column grid with inline tags, a translation memory per project or client, live glossary highlighting, and thirteen QA checks that never block you.

Deadline ahead

The Mac is running out of native CAT tools.

Apple is retiring Rosetta 2, and when it goes the Java-based CAT tools that depend on it stop working on Mac. LinguaTrans is built natively in Swift, opens the same bilingual files, and is not going anywhere. Move your work over before the deadline, not after it.

Five companion apps.

Terminology and Pro plug straight into the translation workflow, LinguaReview takes it off the desk, and Admin and Studio round it out. The file is the contract between apps.

LinguaAI Pro

AI text processing on your Mac that hands files to LinguaTrans for AI pre-translation and review.

All features →

LinguaAI Terminology

Extracts glossaries and style guides with AI, converts Word, Excel, subtitles and XML to XLIFF, and rebuilds the document.

All features →

LinguaAI Admin

Track clients, projects, invoices and finances in one app, with AI-powered insights.

All features →

LinguaAI Studio

Your AI assistant across iPhone, iPad, Mac, Apple Watch and CarPlay — chat, transcribe, transform.

All features →

LinguaReview

Read the pretranslation as continuous prose on iPhone, iPad or Mac, flag whatever reads wrong, and hand the flags back to LinguaTrans as a small sidecar file. It never writes the file, so a reading session cannot damage anything.
