PVUpaper is a desktop writing app that keeps your whole project in one place: your manuscript, your notes, and your plans. Write in a focused editor with spellcheck, organize notes and chapters in the Dossier, open up to four documents side by side, and map out characters and places on planning boards.

What makes it different is that it’s entirely yours. It works offline, needs no account, and keeps every project on your device, with backups and snapshots built in. Its continuity checks read your manuscript for slips and show you the exact passages behind each one, so you decide what to change. Nothing in PVUpaper writes or suggests a word of your story.
