AI Interpreter Service "CoeFont Interpreter" Now Supports Document Translation for PDF, Word, PowerPoint, and Excel

CoeFont Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Shogo Hayakawa; hereinafter referred to as "our company") is pleased to announce that its AI interpreter service, "CoeFont Interpreter," will begin offering a document translation function at the end of June 2026.

This new feature will enable AI to translate files in four formats (PDF, Word, PowerPoint, and Excel) while preserving the original layout and design, allowing users to download the translated documents in the same format. Furthermore, by pre-training the AI with company-specific product names, industry jargon, and internal abbreviations using video, audio, and document data, these terms can be accurately reflected in document translations. This allows for translations that adhere to a company's own notation standards, overcoming the common issue of mistranslations or literal translations of specialized terms often found with general AI translation services.

"CoeFont Interpreter," which has primarily offered voice interpretation services, will now evolve into a comprehensive service covering global communication by also addressing the need for document translation in business settings.

Background: "Meeting Translation" and "Document Translation" Always Occur Together

In business environments where international conferences and collaboration with foreign staff are commonplace, there is a constant need for both real-time voice interpretation and document translation for materials, minutes, and contracts. However, it has been common practice to use separate tools for voice interpretation and document translation, burdening staff with the operational costs of managing multiple tools, multiple service contracts, and individual security policy checks.

Our company has been working on developing the document translation function to unify these fragmented translation tasks and create an environment that can seamlessly handle everything from voice to documents.

Feature Overview: Translated Files Ready for Immediate Use Without Altering Format

1. Supported Formats

Supports four formats: PDF, Word (.docx), PowerPoint (.pptx), and Excel (.xlsx). Simply upload your file, and you can download the translated file in the same format.

2. Format-Preserving Translation

Maintains the original layout, fonts, tables, and placement of illustrations even after translation. There is no need to recreate documents for translation, and they can be immediately shared internally or sent to business partners after translation.

3. Support for Specialized Terminology Dictionaries

Company-specific product names, industry jargon, and internal abbreviations can be reflected in document translations by pre-training the AI with video, audio, and document data. This enables translations that adhere to your company's notation standards, overcoming the common issue of mistranslations or literal translations of specialized terms often found with general AI translation services.

4. Integration with Voice Interpretation

Document translation can be completed within the "CoeFont Interpreter" account. From pre-meeting materials to real-time interpretation during meetings and post-meeting minutes translation, all can be handled without switching tools.
