About this app

This text editor was developed by a professional writer specifically for writing manuscripts in Japanese.

It was designed with the highest priority on keeping your writing flowing. You can start writing immediately after launching it, and freely type in your thoughts as they come to you, just like in a notepad. It supports everything from drafts for blogs, notes, and social media posts to full-fledged novels and articles.

Completely free. No ads are displayed. No account registration is required, and it doesn't have any internet access, so your written manuscripts will never be sent externally.

It can be used safely offline.

[Main Features]
・Dialogueless — No confirmation dialogs for saving or closing. You can concentrate on writing.
・Full-width character count — Always displayed in the status bar. You can see the number of selected characters at a glance.
・Automatic save function — Automatically saves at specified intervals (off by default). It also works when creating new documents, so no saving operation is necessary.
・Line break rules (formatting) — Automatically wraps lines at specified character counts to prevent punctuation, closing parentheses, and small characters from appearing at the beginning of lines. Furthermore, the unformatting function, which removes line breaks and unnecessary spaces, recognizes the beginning of paragraphs, including leading spaces and symbols.
- Features convenient for writing manuscripts, such as a search results list (with surrounding context for hits) and date/time insertion.
- Tab function — Allows you to open multiple files simultaneously.
- Cursor pad function — Offers a joystick mode for freely moving the cursor by sliding, and a cross-key mode for moving one character at a time with each tap (can be turned on or off). A character selection mode is also implemented.
- High-speed scrolling — Holding down the right edge of the screen activates scroll mode for high-speed scrolling.
- Customizable menu bar — Arrange frequently used functions in your preferred order.
- Dark mode support — Choose from following device settings / Light / Dark.
- External keyboard support — Supports keyboard shortcuts.

What’s new

【v2.2の変更点】
・推敲機能(β)実装。長すぎる文や助詞の繰り返し、同じ語尾の連続、表記揺れなどを検出して指摘します(AIではありません)
・簡易アウトライン機能として目次機能(β)を実装。行頭に印(# / ## )を付けて見出しを宣言。目次ウインドウで、見出し以下の段落単位で順序を入れ替えられます。印がない場合はアプリが推定で見出しを拾い、印を打つことで入れ替えが可能になります。指で上下に動かすと順序が変わり、右にずらすと小見出しになります。適用ボタンを押すまでするまで本文は変わりません
・見出しの印として「#」を使うので、簡易Markdownとしても使用できます。それ以外のMarkdown記号には対応しません。印は文字数にカウントせず、提出時には一括して削除できます
・タブレットの横画面で、本文を右または左に寄せる機能を実装。空いたスペースにGboardやカーソルパッドを置けます
・カーソルパッドにバイブ機能を実装(オンオフ可)
・スペース削除時に英文の半角スペースは保護するよう変更
・cmなどの単位を半角英数に揃える機能搭載。英単語は全角、単位は半角などと使い分けられます
