A product spec, screen plans, and build steps for your coding agent.

Your first Build Kit is free with a verified email.
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.

Champagne, decoded. Parcelles is a detailed, data-driven explorer of Champagne: its 8,000+ vineyard parcels and the champagnes made from them. From the chalk beneath the vines to the bottle in your hand, Parcelles brings it all together in one beautiful app, on iPhone and iPad. EXPLORE THE REGION Browse the entire Champagne wine region on a detailed interactive map. Tap any parcel to see its name, village, and classification instantly. Search across every vineyard, village, producer, and champagne. On iPad, the map and a floating detail panel sit side by side. EVERY CHAMPAGNE Explore the whole champagne catalogue of the region, from the grandes maisons to the smallest growers. Browse, search, and filter by cru, style, dosage, and grape variety to reach exactly the bottle you have in mind. INSIDE EVERY BOTTLE Open each bottle up. See the blend grape by grape, trace any cuvee back to the exact parcels it draws from, and read a portrait of the wine. Producer profiles connect every house to the land behind it. SAVED, PINNED, MEASURED Keep vineyards, producers, and champagnes on your account, each with a note and in lists of your own. Drop a pin with a note anywhere on the map, and measure a row, a parcel, or the elevation along a line. KNOW YOUR TERROIR Every parcel analyzed with altitude, slope, aspect, sun exposure, soil composition, and rankings against all of Champagne. Understand what makes each vineyard unique. WHAT LIES BENEATH Geology overlays, contour lines, and hillshade reveal the land that shapes each vineyard. The vineyard diorama builds any parcel as a lit 3D model with its surroundings, and a sun you can move through the day and the year. Elevation profiles show the surface geology and the rock layers below, reconstructed from real boreholes. DECADES OF CLIMATE Growing degree days, rainfall, frost, and sunshine decade by decade since 1950. See how climate has shaped the vines, the best years and the worst, all-time records, village by village. Plus a Climate Outlook with CMIP6 projections through 2040. SEASON TRACKER Follow the growing season day by day. Growing degree days, a 3-day forecast, frost warnings, vintage archetype forecasts, and harvest predictions, village by village, updated daily. AROUND ME Visiting Champagne? Discover which vineyards surround you, sorted by distance. Stand on the terroir and read it from your phone. COMPARE AND FIND TWINS Compare up to 10 vineyards side by side, and find their terroir twins: vineyards that share similar soil, altitude, and exposure anywhere in Champagne. PRICING Free: the interactive map, every parcel with names, villages, and classifications, search and browse across the whole champagne catalogue, and the Climate Outlook with CMIP6 projections through 2040. No account needed.

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.
Not assessed in a Build Kit yet.
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.
