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.

Not sure what to cook tonight? lopu helps you build a weekly meal plan, find dinner ideas faster, and keep a grocery list right next to your recipes — all in one place, without the daily decision fatigue. How it works: 1. Pick your days — lopu suggests meals for breakfast, lunch, and dinner based on your preferences and what you already have at home. 2. Browse recipes — healthy dinner recipes, quick dinner ideas, and meals made from what's already in your fridge. Nothing complicated — just food you'll actually cook. 3. Build your grocery list — one list for all planned days, grouped by product type: dairy, vegetables, proteins. Shop once, cook all week. Why lopu works: — A weekly meal plan in minutes. No more "what to cook tonight?" — your meal planning is done, meals are spread across the days, and nothing needs to stay in your head. — Grocery list tied to your meals. You don't just see a list of items — you see exactly what to buy and for which recipe. No forgotten ingredients, no overspending on things you don't need. — Cook from what you have. Add the ingredients sitting in your fridge — lopu finds recipes that use them so nothing goes to waste. Less food thrown away, more value from what you already bought. — Works for the whole family. Family recipes, quick weeknight dinners for kids, healthy lunches, and adult dinners — one plan that covers everyone without the back-and-forth. — Healthy eating without the complexity. No calorie obsession, no macro counting — just clearer daily choices, better meal prep habits, and a simpler routine that actually sticks. — Flexible for your week. Plans changed? Swap one meal — lopu recalculates your grocery list automatically. No spreadsheets, no sticky notes, no chaos. What a real week with lopu looks like: Monday — oatmeal with berries, chicken soup, grilled salmon with veggies. Tuesday — avocado eggs, leftover soup, pasta with tomato sauce. Wednesday — yogurt with fruit, tuna salad, baked chicken with potatoes. Thursday — smoothie, quick lunch from the fridge, beef patties with quinoa. Friday — granola, light soup, homemade pizza on thin crust. Saturday/Sunday — healthy dinner recipes for a relaxed weekend, or a meal prep session for the next week. All of this — one grocery list, one trip to the store at the start of the week. Who this is for: — You want a healthy meal planner that actually fits your weekly schedule without spending hours planning every single meal from scratch — lopu does it for you. — You spend too much time deciding what to cook tonight and want a system that removes the daily guesswork before you even open the fridge. — You want to shop smarter — one grocery list, one trip, based on a real weekly meal plan — instead of buying random items that don't form complete meals. — You're looking for quick dinner ideas or easy meal prep that works on busy weeknights when cooking elaborate meals isn't realistic. — You want to eat better — less takeout, more home cooking — but without complicated diets, calorie tracking, or apps that make healthy eating feel like a second job. Sunday evening. In 5 minutes, you've built your weekly meal plan, checked your grocery list, and know you're shopping once — Monday morning. The rest of the week? Just open lopu and cook from the plan. Try lopu — and let "what should I cook?" stop being a question you have to answer every single day.

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.
