Key features

Faster localization of software

The what-you-see-is-what-you-get (WYSIWYG) editing approach displays software menus and dialog boxes in the relevant editors in just the same way as when the software is running, for maximum translation quality.

Reuse your translation resources as effectively as possible during software localization.

Passolo is tightly integrated with our leading translation software, Trados Studio, MultiTerm, Trados Team, Trados Accelerate and Trados Enterprise, giving you full access to existing translation assets and terminology glossaries.

Increased translation quality

Translators and localization managers can take advantage of the widest range of testing functionality in the market.

Built-in quality assurance monitors every text entry and highlights any errors such as truncated texts, overlapping control elements and missing access keys. Tests can be carried out on selected sections of text or even the entire project.

“Thanks to Passolo, we quickly achieved a very high level of automation throughout the entire software localization process – from generating the projects, through to the pre-translation and creation of language files, and on to validation and quality testing.”

Frank Fürniß, product development

“Passolo is precise in distinguishing programming code from user-interface content to be translated, and preventing project managers or translators from breaking the build.”

Yuka Kurihara, Director of Globalization

“Passolo is fast and efficient – sometimes it takes a few seconds instead of hours to retrieve translations. Adopting Passolo has freed us from the technical constraints of our previous tools and led to a 40% increase in translation speed.”
