Plan chapters, write scenes, keep your Encyclopedia nearby, and track every draft in one calm place. No project-management clutter. Just the work and the words.
Cursyv brings your editor's notes into the margin and your Encyclopedia to the page. The only co-writer here is a human you chose — read-only review without turning the desk into a content pipeline.
Interactive demo — sample manuscript, not a live session
The writing surface
The city smelled of rain and old paper. Elara pressed her palm against the cold glass and watched the street below dissolve into amber and fog.
She had three hours before the archive closed. Three hours to find what the letter had promised — and to decide whether she actually wanted to.
What we stand for
Not marketing claims — these are the product decisions baked into Cursyv from the first line of code. They shape every feature we build and every feature we don't.
Inside the app
History
Cursyv saves dated snapshots while you work. Open any earlier version, read it, or restore it in one step — without overwriting what you have now.
Named snapshots with Proof Record fingerprints.
“I rewrote my entire second act, hated it three weeks later, and went back to the original in about ten seconds. I didn't lose a single sentence.”
Encyclopedia
One reference file for the facts you have already chosen: who people are, where scenes happen, which objects matter. Names in the text link straight to their card so you are not hunting through folders at midnight.
Tap a [[linked]] name above to open its card.
What it does
Lore stays in one reference — linked to the manuscript, typed the way you already write.
Three kinds of entry. One Encyclopedia beside your draft.
Each sleeve holds one entity type — the same citation cards you open from the manuscript in Studio. Tap a sleeve to draw its card; tap again to shelve it.
Wrap any name in [[ ]] while writing and Cursyv creates a Encyclopedia entry for it automatically. Click any name to open its card without leaving the page.
Eye colour from Chapter 2. The thing she said to her father. The lie she hasn't told yet. Keep it all in one card. Never contradict yourself again.
Which side is the door on? What does it smell like? Is it always cold or only in winter? Note it once. Reference it every time you return.
The compass, the letter, the knife. Track where it came from, who's had it, and what it means. Objects carry weight — give them the space to hold it.
Every character, place, and object shows what it's connected to. Pull on a thread and see the whole web it belongs to.
Every entry shows you exactly which chapters it appears in. Checking where you last mentioned the letter takes one second, not a ctrl-F hunt.
Cursyv for desktop is built on Electron — a native app for macOS and Windows that works entirely offline. Your manuscript never needs a connection. Sync to the cloud when you want to. Write when you don't.
macOS & Windows · $49 one-time at launch · No spam, ever.
Sessions
A lightweight companion that sits alongside your manuscript. Not a task manager, not a sprint tracker. Just a quiet place to hold what you're working on — and catch the thought that surfaced mid-paragraph before it disappears.
Keystroke sounds
Every key you press has a sound. Not a notification, not a ping — a click. A clack. The small, satisfying proof that a word just happened.
Typing sound is optional and instant-mutable — designed for writers who find a little ambient feedback keeps them in the sentence.
What the desk holds
Chapters open on a page tuned for long sits — focus when you want it, autosave either way.
The Encyclopedia keeps characters, places, and lore beside the sentence you are writing.
History holds named drafts you can restore — the arc of how the novel was written, not a folder of mystery files.
Proof travels with the manuscript when you need a record of authorship.
The work stays yours
Cursyv does not generate or rewrite your prose. That boundary is quiet — expressed through what the product is, and through Proof when you need a verifiable record. Your manuscript is not training data.
A workspace for writers who still believe the writing is the point.
Proof
Copyright is automatic. What most writers don't have is proof. Cursyv builds it quietly in the background — every draft saved is a timestamped, verifiable record of your work's entire creation.
"My first manuscript spent two years in submission. Knowing I had a timestamped record of every draft meant I stopped losing sleep over someone stealing it."

Excerpt at this draft
“She put the compass on the table between them. Neither of them reached for it…”

Edit
Mark chapters as ready, bundle the ones you want reviewed, and send your editor a clean link. They leave margin notes. You see them in Cursyv. Nobody touches a Word doc.
Who it is for
Chapter-scale drafting with subplot continuity, an Encyclopedia that stays beside the prose, and named History entries you can restore with one click. Everything a novel needs in one desk.
