Private Quality Machine Translation Anywhere

For translators, agencies, language service providers and enterprises

Slate machine translation (MT) applications, powered by your translation memories, run privately on-premises with MS Windows and present MT suggestions in your favorite computer-assisted translation (CAT) tool.

Why Use Slate MT Applications?


Slate machine translation (MT) applications protect your privacy. They run on your computer without the Internet and without logging your activities. Confidentiality and privacy are safe.


Slate MT applications offer suggestions with your words and style. It’s a natural benefit of using your translation memories (TMs) on your computer. You edit less and finish more work in less time.


We created Slate MT for translation professionals, like you, to use modern MT technologies wherever they go. Slate MT applications enhance productivity and expand capacity without the cloud.

Unique Features for a Better MT Experience

Unlike MT service bureaus (Google, Microsoft, others), we make software applications that protect your personal privacy based on our decades of experience working with translators and agencies.

Personalized Core

The PC revolutionized the world because it replaced mainframes computers and experts in data centers with the personal devices we all use every day. Likewise, Slate MT applications replace machine translation technology and experts in cloud-based service bureaus with your PC under your control to use every day.

Perfect Privacy

Your Slate MT application runs in the background on your personal computer. It doesn’t log your activities, track your relationships or record your work habits. It doesn’t send anything to the Internet. Your TMs are safe and confidential on your computer where prying eyes can’t watch what you’re doing.

Artificial Intelligence & Machine Learning

The advanced artificial intelligence (AI) and machine learning (ML) technologies in Slate MT applications run on your computer. They learn from as few as 80,000 segment pairs in your TMs to deliver quality suggestions with your mastery of words and in your personal translation style.

Unmatched Quality

MT service bureaus adjust their technology to serve a wide range of translation needs everywhere in the world through the Internet. As a result, their quality never reaches the technology’s full potential. A Slate MT application adjust to serve one professional on one device. Whether you are one translator, one agency or one enterprise, you experience the technology’s optimal professional quality.


Slate Desktop Edition supports any combination of 33 languages (click here) and the number of supported languages keeps growing. That means your Slate MT application with your TMs can translate between 1,056 language pairs with more language pairs to come.

CAT Integration

The Slate MT engines you create from your TMs automatically appear as machine translation providers in your computer-assisted translation (CAT) tool. We support you with Trados Studio, memoQ, CafeTran and OmegaT, with more to come.

Intuitive Experience

Slate MT applications are packed with powerful, mature MT technologies inside an easy-to-learn, intuitive user experience. Whether you’re a technophobe or research engineer, you’re up and running in no time because you reuse the knowledge you already have about TMs and CAT tools.

No Subscriptions

MT service bureaus (Google, Microsoft, KantanMT & others) charge a fee for professionals to use their services. These costs continue as long as you maintain your subscription. With Slate MT applications, you pay a one-time perpetual license fee and your costs stop. No per-word fees. No royalties. No subscriptions.

Terminology Control

It is tedious to repeatedly change someone else’s words and fix incorrect terminology. Slate MT applications learn you use “email” and never use “e‑mail” from your TMs. You can also configure Slate to use your glossaries to force client-specific terminology.


We’re the only company that pairs the world’s most popular business productivity operating system, Microsoft Windows desktop, with the world’s most popular MT productivity technology. You prefer Linux? We do that, too. Need MacOS? Please subscribe to our newsletter.

What Our Customers Say

I’m always interested in what technology can do for a human art like translation, and so I signed up for Slate Desktop. Compared with attempting a Moses installation, it’s a walk in the park. For me, the benefits are confidentiality and user control, and I started using it on a real-life project the day after I installed it. The trajectory looks promising and there’s always the happy compulsion to build a better engine. I applaud what Slate Rocks is doing.

Bríd Ní Fhlathúin (en-ga)

With Slate Desktop, Slate Rocks has nailed down every single requirement for non-technical individual translators to leverage MT. It’s a Windows-based solution with a GUI and the confidentiality of their own desktop. It’s a very unique opportunity and I hope the translation community will take full advantage of it.

Anonymous Translator 1 (en-es)

Slate has solved the dichotomy between confidentiality and machine translation. It has the edge not only in look-up times but also in making quick tweaks to a terminology file. Adding a couple of terms or variables for a specific project is a breeze. For me, a customised MT engine is an additional tool in my toolkit, and it’s the sum of all these tools that makes me highly productive in terms of output per hour.
