Turn waiting into writing. Most people who want to write a book never finish one - not for lack of ideas, but for lack of time to sit down. Authora is a mobile writing companion built for the life you actually have. Waiting rooms, commutes, flight delays, lunch breaks - the minutes that usually disappear into doomscrolling, reclaimed for the book you've always meant to write. WRITE ANYWHERE Six format templates - novel, journal, manuscript, academic paper, non-fiction, poetry collection. Rich text editor optimised for phones and tablets, not a desktop UI stuffed onto a small screen. Auto-save every two seconds. Focus mode for distraction-free writing. Preview mode to read your draft as a reader will see it. STORYBOARDING THAT MATCHES HOW WRITERS THINK Characters with bios, traits, and relationships. Plot arcs with scenes you can link to chapters. World-building notes. Colour-coded labels. Keep the people, places, and threads of your story organised without leaving your phone. FROM BLANK PAGE TO PUBLISHED BOOK Authora isn't just a writing app - it's a self-publishing pipeline. When your draft is done, add a cover image, and export as EPUB or PDF that's ready to upload straight to Amazon KDP, Apple Books, or Kobo. Front matter, back matter, TOC, metadata - all handled. Your finished book goes into your personal library inside Authora too, readable with a built-in ebook reader. No separate formatting tool. No desktop required. Draft to published, all on your phone. CAPTURE ON THE GO Speech-to-text dictation with live transcription. Chapter import from .docx, .rtf, and .txt - start with existing drafts, no retyping. On-device writing analysis flags passive voice, adverb overuse, clichés, and readability issues as you write. FREE FOREVER, PREMIUM WHEN YOU'RE READY Full writing experience, export, personal library, and a starter storyboard - all free, all local, no account required. Premium ($4.99/mo or $49.99/yr) adds encrypted cloud sync and backup across phone and tablet, unlimited storyboarding, inline figures with captions, and priority support. PRIVATE BY DEFAULT Free users never sign in. Premium users' chapters, world notes, character bios, and plot descriptions are encrypted at rest with AES-256, and in transit with TLS - even in a breach, your draft stays unreadable. Biometric app lock on both platforms. We never read your work, never train on your writing, never sell your data. BUILT FOR PHONES AND TABLETS Native iOS App. Dark and light theme. Responsive layout on tablets. Biometric unlock. Full offline support. Dashboard showing word count trends and your completion stats. The book is already in you. Authora is where you finish it.

Simple. Private. Always with you. Amethyst is a minimalist writing app for novelists. We give you the tool and remove the friction, so you can just write. Built mobile-first, so there is nothing standing between your idea and the blank page. Write any time the idea strikes, preview your novel with beautiful formatting, and export your finished product. All on the go. Your readers are waiting: • 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. • Preview 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 birth dates. Amethyst is built for novelists by novelists: • Absolute privacy. We don't collect personal information. No account, no login, no telemetry, no keystroke tracking. • Every word is written to local storage the moment you type it — no connection needed, ever. When you're connected, Amethyst backs up automatically. • 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 all of that 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. Your data is yours: Amethyst never sends your novels or projects to third parties, and Shinano Labs will never sell or share your usage data. Your backups are store securely in your own iCloud storage, always available but always private. You can delete your account securely at any time (though we'd be sad to see you go!). Shinano Labs never has access to your writing or your profile data. Your stories deserve a home that respects your time and your privacy. Start your next chapter today.
