The exact meaning of source content is critically important in legal matters. An entire case, millions of dollars in damages, and a client’s reputation can all hinge on translation accuracy.

You can rely on the depth and superior performance of our services, backed by certification to 3 ISO standards for quality and security management.

It translates 2 billion words per year (often running 24 X 7), and is backed by Linguistic Systems’ 50+ years of exceptional translation performance.


Bringing together two multinational organizations is complex and risky. It’s even more treacherous when critical documents such as contracts, financial reports, marketing analyses, product strategies, and intellectual property filings are in multiple languages. Ai Translate by LSI™ (formerly STS) has supported landmark M&A investigations and numerous DOJ second requests for more than 50 years.


The Ai Translate Pluginfor Relativity (formerly the LSI Translation Plugin for Relativity) is the first full-service plugin to offer translation for Relativity (through v. 9.7) and now RelativityOne. With the plugin, clients can stay current with the latest versions of Relativity, order as many as 6 levels of translation quality, and translate all relevant documents — without leaving the app.
