PLaMo Translate

The service provides Japanese‑English translation using a large language model that has been trained extensively on Japanese data. It generates fluent, context‑aware translations for plain text, preserving the original layout when handling whole documents such as PDFs, Word files, PowerPoint decks, and Excel spreadsheets. A desktop application for macOS lets users invoke translation with a shortcut key, and a browser extension can translate entire web pages while keeping formatting and typography intact.

Target users include professionals who need to gather information from foreign sources, create multilingual content, or translate business documents. The tool supports terminology management to improve accuracy for personal names and internal jargon, and it offers a file‑upload workflow that maintains the structure of complex documents, including equations and tables.

What distinguishes the service is its focus on Japanese language quality: the underlying model contains a higher proportion of Japanese training data than many comparable models, resulting in higher‑precision day‑to‑day translation and more natural phrasing for both Japanese‑to‑English and English‑to‑Japanese tasks.
