Rosetta Launches Intuitive UI for Editing AI-Translated Text While Maintaining Layout, Revolutionizing "Common Practice" in Post-Translation Editing – Update for High-Precision Industrial Translation AI "T-4OO"

Rosetta Co., Ltd., a Material Group company that develops and provides Japan's No.1* AI translation service, announced on April 28, 2026, the launch of a new user interface (UI) for its high-precision industrial translation AI "T-4OO" (T-Four-O-O).

For the post-translation editing screen in "High-Precision" mode, in addition to the conventional "parallel display format showing source and target texts side-by-side," we are now providing an "intuitive UI (layout editing format)" that allows users to edit the translated manuscript while viewing it in its actual layout, incorporating AI suggestions. Users can now choose between the old and new editing screens depending on their purpose and task. This significantly advances translation efficiency and user experience.

■ "Layout Editing Format" Translation UI

With this revision, users can now edit while directly confirming the final translated image, significantly improving work efficiency compared to the conventional parallel format. Our verification shows a 10-20% reduction in man-hours, depending on the amount of layout adjustment. In terms of working hours, a task that used to take 5 hours will now take 4 to 4.5 hours. Furthermore, because users can work while visually grasping the final form, it not only speeds up the process but also improves the quality of the translated document itself.

Existing users had previously expressed feedback that "when editing in the parallel format, it is a two-step process because layout adjustment is required after editing the translation." Specifically, there was a challenge where if the translated text was long and caused layout issues, the edited translation had to be revised again.

Regarding the renewal of the editing screen, user monitors commented, "With this new function, it's efficient to adjust the layout while editing the translation." The development manager also commented, "We thoroughly pursued the sensation of directly manipulating the translated document as is. This is a big step that changes the common practice of translation editing."

■ Newly Introduced "Consistency Check" Function

Furthermore, this renewal introduces a new "Consistency Check" function. This function automatically detects editorial oversights such as inconsistencies in expressions with previously translated documents, or fluctuations in numbers, proper nouns, and terminology. For instance, in cases like contracts or technical documents where consistency of terminology affects the reliability of the output, mistranslations and uncorrected omissions can be prevented. As a result, it is now possible to ensure the stability and consistency of translation quality while improving work efficiency.

■ Supporting a Wide Range of Industries with Strong Specialized Translation

"T-4OO" supports over 2,000 specialized fields, including pharmaceuticals, manufacturing, legal, patents, and finance, and possesses technical capabilities cultivated through a customer base of over 6,000 companies. With this new UI, even in industries requiring high levels of expertise, important translation tasks such as specialized documents, contracts, research reports, patent-related materials, and international marketing documents can be performed more accurately and intuitively.

Even for translations containing specialized terminology and industry-specific expressions, generative AI suggestions can be flexibly incorporated, and corrections can be made while confirming the post-translation layout. This transforms translation work from "just a task" into a "valuable process directly linked to business results."

■ Symbol of the Generative AI Second Phase

In recent years, the use of generative AI has rapidly expanded. We are now transitioning from the "try it out" stage to the "integrate into business to maximize efficiency" stage, and are currently entering the "Generative AI Second Phase." This UI renewal of "T-4OO" can be said to symbolize this era.

"The translated output becomes the final deliverable as is" – by combining the optimal solutions provided by AI with human expressive power, and immediately reflecting them in the deliverables. This approach is the new form of translation suitable for the generative AI era.

■ Comment from Atsunori Shinoda, T-4OO Development Manager:

"Until now, the mainstream editing screen for machine translation has been the 'parallel format,' displaying source and target texts side by side. While this format has the advantage of allowing users to correct translated text by referring to the source, it faced the challenge of not adequately meeting the need to 'edit while maintaining the layout of the document.'

This time, we have significantly revamped the editing screen for the 'High-Precision' mode of our 'T-4OO,' realizing a new editing screen that allows users to edit the translated text while preserving the document's layout. This enables users to perform editing tasks more intuitively and efficiently. We have also added a function to display the source text as needed, further enhancing convenience.

Furthermore, the newly introduced 'Consistency Check' function utilizes generative AI to detect inconsistencies with past translations and editing oversights."
