AI Interpretation Service 'CoeFont Interpretation' Now Supports Document Translation for PDF, Word, PowerPoint, and Excel

CoeFont Inc. (Headquarters: Minato-ku, Tokyo; CEO: Shogo Hayakawa; hereinafter "the company") announces the launch of document translation functionality for its AI interpretation service "CoeFont Interpretation," starting at the end of June 2026.

This new feature enables AI-powered translation of four file formats—PDF, Word, PowerPoint, and Excel—while preserving the original layout and design. Translated files can be downloaded in the same format as the original. Additionally, company-specific product names, industry terms, and internal abbreviations can be pre-trained into the AI using video, audio, and document data, ensuring accurate reflection in document translations. Even technical terms that are often mistranslated or literally translated by general AI tools can now be rendered according to the company’s own naming conventions.

Previously focused primarily on voice interpretation, "CoeFont Interpretation" now evolves into a comprehensive global communication solution by addressing the growing demand for business document translation in real-world corporate environments.

Background: Meeting Interpretation and Document Translation Always Go Hand-in-Hand

In modern business settings where international meetings and collaboration with foreign employees are commonplace, real-time voice interpretation and document translation (e.g., meeting minutes, contracts, presentations) are consistently needed as a paired requirement. However, until now, these two functions have typically been handled by separate tools, forcing users to manage multiple platforms, maintain separate service contracts, and conduct individual security policy checks—resulting in significant operational overhead.

To unify these fragmented translation workflows and provide a seamless environment from speech to documents, CoeFont has developed this integrated document translation functionality.

Key Features: Translated Files That Preserve Format and Are Ready to Use

- Supported Formats

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

- Layout-Preserving Translation

Maintains the original layout, fonts, tables, and image placements after translation. No need to reformat documents—translated files are ready for immediate internal sharing or external distribution.

- Custom Terminology Dictionary Support

Company-specific product names, industry jargon, and internal abbreviations can be pre-trained into the AI using video, audio, and document data, ensuring consistent and accurate translation across documents. Even highly technical terms prone to errors in standard AI translation can now be rendered according to the company’s preferred style.

- Integration with Voice Interpretation

Document translation is fully integrated within the "CoeFont Interpretation" account. Users can seamlessly manage pre-meeting materials, real-time interpretation during meetings, and post-meeting minutes translation—all within a single platform.
