My TextEditor

A simple Japanese text editor born from a real-world writer’s need to set custom line lengths and write comfortably on Android. Built with AI-assisted "vibe coding," this app bridges the gap between precise character count management and beautiful typography—especially designed for the expanding era of foldable smartphones. Developer’s Story As a journalist and writer who drafts articles daily, having a fixed-length line environment is essential for writing and editing. However, I couldn't find an Android editor that fulfilled this need. With the rise of foldables and larger displays, the need for a truly dedicated writing environment became even clearer. Driven by a writer’s perspective, I built this app using AI-assisted coding to focus strictly on essential features without unnecessary clutter. Key Features Custom Line Lengths Set your desired number of characters per line, neatly arranged in a fixed-pitch grid. This makes tracking your character limits effortless during writing and proofreading. Precise Japanese Typography Features custom-built rules for Japanese typesetting, including hanging punctuation (placing punctuation marks outside the right margin) and strict line-breaking rules (kinsoku shori). Your text remains beautifully aligned to the grid without awkward stray punctuation. Clean & Focused Design Stripped of unnecessary distractions, the minimalist interface lets you focus entirely on drafting and refining your prose. Recommended For ・Journalists, writers, and authors who need to write and proofread with fixed line lengths. ・Anyone looking for an optimized writing experience on foldable phones or tablets. ・Writers who appreciate clean, grid-aligned Japanese typography.
