Penmo+ Quiet Writing Notebook

A quiet writing app. Organize your story into series, episodes and chapters. Vertical preview, writing heatmap, draft history and text export. Local and offline.

Penmo+ is a quiet app for writing — and for keeping at it, every day.

Novels, scripts, worldbuilding, notes, ideas, journals — keep all your writing in one notebook.

■ Focus on writing A clean, text-first editor with no clutter. Focus Mode strips everything but your words. Auto-save lets you lose yourself in writing, with a quiet cue so you never wonder if it saved. Adjust the font size and line spacing to taste. Draft history keeps your earlier versions, so you can rewrite without fear.

■ Organize your work Series → Episodes → Chapters, from long novels to short shorts. Reorder episodes and chapters by drag.

■ Vertical writing & ruby Preview your text in traditional vertical writing (tategaki). Ruby / furigana notation (｜kanji《reading》) is supported.

■ A "Read" tab, just for reading A place to revisit your work, separate from writing. Pick an episode from your library and read it as one continuous, vertical flow across chapters. The reading font size is adjustable, separately from writing.

■ See your writing, every day A GitHub-style heatmap shows how much you write at a glance. Streaks, a daily goal and a gentle reminder keep you going.

■ Pick up where you left off Tap "Continue writing" to jump straight back to your last chapter.

■ Take your words anywhere Full-text search, plain-text (.txt) export, and full backup & restore.
