Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

With Magic Diary, even the smallest everyday experiences transform into engaging stories thanks to AI. When you feel trapped by routine or overwhelmed by difficult moments, it offers a different perspective, revealing the kindness, strength, and hope that often slip away. The most surprising part? Everything happens directly on your device, in complete privacy and without needing the internet. With a simple tap, you can create a new page in your diary: choose your preferred genre, write a thought, and let AI transform it into a unique story inspired by your emotions and your days. You can always continue a page you started in the past or mark it as a favorite. Advanced editing: edit the text and give each word its shape. Select the text, tap "Format" and choose bold, italic, underline. Want more? Tap "More..." to change size, color, font and position. This way your stories can reflect exactly how you feel. If you don't feel like reading, the voice synthesizer can give voice to your moments. Share your favorite stories with whoever you want: only the story will be shared. By default, Magic Diary shows the last seven days, but you can apply one of the quick filters or choose exactly the period you want to explore. Thanks to iCloud, your diary follows you everywhere. Pages sync securely and reliably across iPhone, iPad, Mac, and Apple Vision Pro powered by Apple Intelligence. So you can keep writing, remembering, or simply dreaming. If you'd like to send me suggestions, questions, or reports, you can do so anytime at this address: [email protected] And here ends the app description written by me, the developer. But what would happen if I took the description you just read and used it in Magic Diary? It was the day before Christmas, and the air was charged with a special energy. Federica, a young AI researcher, was in her lab, surrounded by monitors glowing with data and code. She had just completed a revolutionary project: Magic Diary, an app that transformed everyday experiences into engaging stories, powered by advanced AI. With a simple tap on the screen, Federica had chosen the "Christmas" genre and written a line: "Snow falls softly, covering the city in a white blanket." In the blink of an eye, her voice was synthesized and a story began to unfold. "Snow falls softly, covering the city in a white blanket. Federica, watching from the window of her laboratory, felt wrapped in a sense of wonder. The outside world seemed suspended, while inside, the warmth of the Christmas lights reflected off the walls of her space. It was a moment of pure magic, an illusion that only Magic Diary could create." Federica smiled, knowing that this day would mark the beginning of a series of stories that would bring some of that same magic into people's lives. With one last tap, she saved her favorite story and prepared to share her creation with the world, knowing that every experience, even the simplest one, could transform into something extraordinary.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
