Amethyst Writer

Simple. Private. Frictionless.

Amethyst is a minimalist writing app for novelists. Chapters, scenes, parts and acts — the real structure of a book, on your phone, with nothing else in the way.

Built mobile-first, so there is nothing standing between an idea and the page. Open the app and write.

YOUR NOVEL, STRUCTURED

• Write scene by scene, or open a whole chapter and write straight through.
• Organize your work into Parts and Acts. Reorder your outline whenever the shape of the book changes.
• Add front matter — title page, dedication, epigraph — when you're ready for it.
• Read the finished manuscript end to end in a single view.
• Search across everything you've written.
• Keep characters and locations in Projects, so you stop losing track of eye colors and street names.

WHY WRITERS CHOOSE AMETHYST

• Absolute privacy. We don't collect personal information. No account, no login, no telemetry, no keystroke tracking.
• Works with no signal. Your manuscripts live on your device. Write on a plane, on the subway, in a basement.
• Saved as you type. Every word is written to local storage the moment you type it — no connection needed, ever. Back up to your own iCloud when you want a second copy.
• Quiet metrics. Daily and weekly word counts, streaks, and your most productive days at a glance. Set a goal app-wide or per novel — or ignore it and just write.
• Your words, exportable. Send a draft out through the iOS Share Sheet, AirDrop, or Files, to a beta reader, an editor, or a publisher. Nothing is locked in.

NO GENERATIVE AI

Amethyst will not write for you or feed your manuscript to an AI model. Your prose is yours, and Amethyst keeps it that way.

YOUR DATA IS YOURS

Amethyst sends nothing to third parties. Your backups are stored securely in your own iCloud storage, readable only by you and only inside the Amethyst app, and you can delete them completely at any time. Shinano Labs never has access to your writing or your profile.

Your stories deserve a home that respects your time and your privacy. Start your next chapter today.
