Storybase helps authors build relationships with their readers, and helps readers engage deeper with books through an immersive and interactive experience. FOR READERS A new way to experience audiobooks and ebooks: immersive, interactive, and connected to the author every step of the way. • Immersive: switch between audiobook and ebook, read and listen in sync, and play soundtracks for exercising, learning, or relaxing. • Interactive: ask the book questions with built-in AI, and share chapters with the people who need them. • Connected: stay close to the author and their world, from the first page to the last. FOR AUTHORS What if your book was the beginning, not the end? • Reach: get your book into more hands with instant share links and customizable offers. • Engage: see who reads, listens, and finishes, and drop AI prompts and calls to action right into the experience. • Activate: turn attention into relationships. Capture contacts and guide readers to your real next step. • Multiply: turn your team, clients, and readers into ambassadors who pass the book forward. A book should do more than sit on a shelf.

AuthorAZ is a private, offline workspace for indie authors to organize books, manage publishing information, write, dictate, store manuscript snapshots, collect quotes, and keep the practical side of an author career in one place. If your book business is scattered across folders, spreadsheets, cloud drives, old files, writing apps, and half-remembered notes, AuthorAZ gives every book a clean private home. No AI reading your work. No AuthorAZ cloud. No account needed. No data or user tracking. Everything lives on your device. Your library is encrypted locally, and backups only leave your device when you choose to export them. WRITE WITHOUT SENDING YOUR WORDS ANYWHERE Create and edit writing projects directly inside AuthorAZ. Draft chapters, scenes, notes, or entire books in a focused writing workspace connected to the rest of your book information. Your writing stays on your device. AuthorAZ does not upload your manuscript, analyze your prose, rewrite your sentences, or send your work to an AI service. DICTATE ON YOUR DEVICE Prefer speaking to typing? Use dictation to turn your voice into text inside the writing workspace, using supported on-device speech recognition. Your manuscript stays in your private AuthorAZ library rather than being processed by an AuthorAZ server. BUILT FOR AUTHORS WITH MORE THAN ONE THING TO MANAGE AuthorAZ helps you organize: • Pen names and author identities • Books, series, statuses, and release dates • Writing projects and chapters • ASINs, ISBNs, BISAC categories, prices, keywords, descriptions, and A+ notes • Ebook, paperback, hardcover, audio, and variant cover slots • Store and reader links • Quote banks and quote tags • Manuscript snapshots • Notes and book-specific reference material ONE-TAP COPY FOR DAILY AUTHOR WORK Tap to copy titles, subtitles, identifiers, prices, keywords, descriptions, buy links, and full metadata sheets. AuthorAZ is designed for repetitive publishing tasks, whether you manage one book or an entire catalogue across multiple pen names. IMPORT MANUSCRIPT SNAPSHOTS Import a .txt, .docx, or .epub file as a read-only manuscript snapshot. Your original file is never edited. Once imported, you can: • Search across your manuscript text • Listen with on-device text-to-speech • Scan for quotable lines • Save quotes to your quote bank • Check manuscript health stats • Bookmark and flag lines for review • Re-import a newer snapshot when your manuscript changes HEAR YOUR BOOK BEFORE READERS DO Use on-device text-to-speech to listen sentence by sentence. Adjust speed, choose a system voice, jump between chapters, bookmark your place, or flag lines that need attention. No audio is uploaded by AuthorAZ. No manuscript is sent to an AuthorAZ server. FIND QUOTES WITHOUT AI AuthorAZ uses deterministic, on-device filters to help surface potential quote lines. Search for punchy lines, dialogue, questions, emotional lines, chapter endings, or character mentions. You stay in control. AuthorAZ does not write for you, rewrite your work, generate passages, or train on your manuscript. CREATE QUOTE CARDS Save your favorite lines and turn them into clean quote cards for social media. Choose the format, background, and display elements, then export a full-resolution PNG with no watermark. LIGHT OR DARK. YOUR WORKSPACE. Use AuthorAZ in light mode or dark mode and choose the workspace that feels right for the way you work. PRIVATE BACKUPS YOU CONTROL AuthorAZ creates encrypted backup files that you export yourself. Save them wherever you choose and restore them later with your password. AuthorAZ does not keep a copy. TRY EVERYTHING FREE Start with a full 14-day trial. Then unlock lifetime access with one payment. No recurring subscription. AuthorAZ is for indie authors who want to write, organize, search, listen to, and manage their books without handing their creative work to another cloud platform. Your books. Your words. Your device.
