About this app

Tsuzuri is writing software designed for writing in Japanese.

By removing unnecessary features from word processing software and adding document synchronization and Japanese-specific formatting features such as vertical writing, ruby ​​text, and emphasis marks, it creates an environment that makes it easy to write text-based manuscripts such as novels, screenplays, essays, and various articles.

■ Document Management by Project
Tsuzuri allows you to manage documents in "project" units.
Project contents are automatically synchronized with other devices, including Android, Windows, Mac, iPhone, and iPad, so you can continue writing a document you started on your home computer on your smartphone.
Within a project, you can manage your text by dividing it into detailed sheets, such as chapters and sections, allowing you to start writing from a sentence that comes to mind, or rearrange the order of sentences later, building your document through structural trial and error.

■ Formatting and Display Designed for the Appearance of Japanese Text
Tsuzuri offers detailed display settings required for Japanese text, including formatting options such as ruby ​​text (furigana) and emphasis marks, as well as vertical writing display and the ability to display emphasized text in Gothic font rather than bold, even when the surrounding text is in Mincho font.

■ User-Friendly Functionality and Operability
You can mark drafts or notes you want to temporarily set aside as "memos," and highlight sections you want to rewrite later.
These memos can be instantly hidden to check the appearance of your manuscript.
