One license activates on up to 3 machines, across Mac, Windows, and Linux. If you get a new computer and need to free up a license, deactivate the old one from inside the app, or email me and I'll free up the slot.

The 30-day trial is available so you can be confident before you buy. But if you do purchase a license and decide it isn't the right tool for you, you can request a full refund within 14 days. Just email me at wesley@opuswriter.app and I'll take care of it.

No. Every update throughout version 1 is free. Somewhere down the road I may release a paid 2.0 with significant new functionality. If that happens existing customers would get a deep upgrade discount, but that's nowhere on my roadmap. The features I want to ship in version 1 will keep me busy for years.

OpusWriter does not have AI. What OpusWriter does have is the completely optional ability to connect your own AI (and instructions on how to do this) to unlock additional editing/feedback features. Even if you connect your own AI and use those additional features, it will not write your story for you. I feel strongly that books should be written by humans.

On your computer, wherever you save it. There's no cloud, no account, no upload, no telemetry. Your project is a single .opws file that you can back up, copy to another machine, or open with any ZIP tool if you ever need to. Your words are not locked in.

Word documents (.docx) import directly, with chapter breaks auto-detected. For Scrivener, compile your project to .docx first and import that. You can also paste prose straight into the editor.

Not at all. OpusWriter has extensive planning tools, but every one of them is optional. If you're a pantser, open a chapter and start writing — the editor is clean and focused, and the planning modules stay hidden until you decide you want them. There's even a "Pantser" workspace preset that hides them by default.
