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.

Astral lets you force anything and produce any small object from your phone. Created by Henry Harrius and Marc Kerstein, Astral includes *two* effects: the best way to force anything, and the best way to produce an object. These are even better when combined together. Unlike other object production effects, using Astral's force mode lets your spectator seemingly decide upon which object will be used, making the object's production seem even more impossible. Force anything: Astral uses a carefully developed forcing mechanism that feels totally natural, whilst ensuring the screen always remains in view. Make something appear: Whether you drag it or time it, Astral lets you make any small object appear in whichever way works best for you. Astral includes advanced but easy-to-use features, such as: * Advanced AI Cutting-edge AI automatically extracts any small object from a photo, making Astral super easy to use. * Quick Produce Mode Found a small item that would be perfect to produce? Astral's "Quick Produce Mode" combined with its AI image extraction ensures that you're ready to perform in no time. * Two Effects, One App Astral gives you the fairest selection process with the cleanest production. Combining these gives the feeling that *any* object could have been produced. And more... - Create and store multiple presets to customise your performance. - Force any object in a natural way before production. - Store separate force and production images the object. This app is for entertainment purposes only.

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.
