Ghostwriter is the AI-powered book writing app that takes you from a rough idea to a polished manuscript — without staring at a blank page. HOW IT WORKS Ghostwriter follows a proven six-step authoring flow designed for people who have stories, expertise, and ideas but struggle to organize them into a book: 1. Start with a topic. Tell us what your book is about — one sentence or a full page. We meet you where you are. 2. AI builds your structure. Ghostwriter generates a custom Table of Contents with chapters and sections tailored to your topic. Review it, tweak it, make it yours. 3. Detailed blueprints. Each chapter gets objectives, goals, and section breakdowns — the skeleton that makes your book work. 4. AI interviews you. This is where the magic happens. Ghostwriter asks targeted questions designed to pull your unique stories, insights, and expertise out of you, section by section. Answer by typing, talking, or uploading documents, photos, audio, and video. 5. AI writes your book. Using your structure and your answers, Ghostwriter drafts every chapter in your voice. Watch it happen in real time in the Writing Theater. 6. Review and refine. Go through each section, approve what works, request rewrites for what doesn't. You stay in control of every word. KEY FEATURES • Voice Interviews — talk naturally with an AI interviewer that asks smart follow-up questions. No typing required. • Structure Studio — design your book's architecture with drag-and-drop chapters and sections. • Content Blueprints — AI generates detailed objectives and summaries for every section before writing begins. • Writing Theater — watch your book come to life with real-time AI writing, progress tracking, and word counts. • Review Suite — approve, edit, or request rewrites section by section with full source-material visibility. • Multi-Input Support — answer questions with text, voice recordings, photos, documents, audio files, and video. • Smart Document Analysis — upload research PDFs and Ghostwriter extracts key themes, quotes, and insights automatically. • Export — DOCX, PDF, EPUB, Markdown, and plain text. • Works on iPhone and iPad, with Mac support on the way. WHO IS IT FOR? • First-time authors who don't know where to start • Entrepreneurs writing thought-leadership books • Coaches and consultants turning expertise into published works • Memoirists capturing life stories • Anyone with a book inside them that needs help getting it out Free to start: every new account includes enough credits to generate a full Table of Contents and Blueprint. Book Credits (available as in-app purchases) cover the interview, full drafting, and rewrites for an entire book. Your ideas. Your voice. Your book. Ghostwriter just makes it happen.

Monitor Websites & RSS Feeds. Get Alerts From Anything. No Servers Required. Get instant alerts when a website changes, an RSS feed updates, or your own scripts and devices need your attention. No accounts, no servers, no technical setup. START MONITORING IN SECONDS Add any website or RSS feed with a tap. Send notifications from any script, server, or web app with a single webhook call. Your device does the work, so there is nothing to host and nothing to sign up for. WATCH THE WEB • Visual change detection with side-by-side comparisons, so you see exactly what changed • RSS, Atom, and JSON Feed monitoring: paste a site address and Notify! finds the feeds for you • Check intervals from 15 minutes to 7 days, per site • CSS selectors narrow a watch to one part of a page, like a price or a stock status ALERTS FROM YOUR OWN SCRIPTS • Every device gets a personal webhook URL that anything can call: a shell script, a CI pipeline, Home Assistant, Homebridge, or plain curl • Custom sender icons and full-size images • Device Groups give several devices one shared URL, so one call reaches every screen you own LIVE ACTIVITIES • Put a live tile on your Lock Screen and in the Dynamic Island, driven by the same simple URLs • Progress bars move in place and countdowns tick on their own, even while the app is closed • Made for anything with a duration: a build, a backup, a delivery, a 3D print, a wash cycle BEACONS: MONITORING IN REVERSE • Instead of telling you when something happens, a beacon tells you when something STOPS happening • Paste its ping URL into a cron job or backup script. If the ping does not arrive in time, you hear about it • The only way to find out that the thing which was supposed to alert you has itself gone quiet EVERY SCREEN YOU OWN • Home screen widgets, and a full year of searchable history SIMPLE FOR EVERYONE, DEEP FOR PROS No coding needed for websites and feeds. Developers get a documented API, Shortcuts and Siri support. YOUR PRIVACY, YOUR CHOICE Local Mode: everything runs on device. No external connections. Notifications Only: a pure push receiver for your webhooks and automations. Server Mode: connect your own ChangeDetection.io instance. MDM ready: alert your teams across managed devices. Notify! can run in local-only mode, which shares nothing but a random device ID and token not tied to any personal information. Notifications Only and Server modes process data with your consent to enable cloud functions such as automation tools, cross-device delivery, and Shortcuts support, and are likewise not tied to any personal information. WHY NOTIFY! Traditional monitoring wants a server, a subscription, and an afternoon. Notify! works in seconds, whether you are tracking a price, following a release feed, or catching alerts from your own code. Start simple and go as deep as you like. Download now and start monitoring in seconds.

Verdict
The clearest difference is in-app purchases: Notify at none against Ghostwriter's 3. Notify also leads on iOS requirement (18.5 vs 26.0). Ghostwriter's advantage is update cadence (every 3 days vs every 6 days). On price, ads and device support there is nothing between them.
