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.

Explore up to $900 in cash advance and loan options in minutes — clean terms, fast flow, no signup. You decide. No pressure now. Payday Brin is built for the moment you need to move quickly — but still want to understand what you’re stepping into. Instead of bouncing between tabs and fine print, you get a clean way to review key details in one place. What Payday Brin helps you do • Get started in seconds with a simple flow • Review cash advance and personal loan details in one place • Compare amounts, estimated rates, and repayment terms side by side • Browse a regularly refreshed list so things don’t feel stale A different kind of finance app No loud promises. No fake urgency. Just a guided flow that keeps the important parts visible: • what you may be eligible for (based on provider criteria), • what it may cost (APR and fees shown when available), • when payments may be due (due dates shown before you proceed), • and what repayment can look like (term details, when provided). How it works • Choose the amount you’re looking for • Review details in a single, readable view • Continue only if it fits your budget and timeline — you stay in control Transparent by design Payday Brin is a comparison platform, not a lender. We do not issue loans, set loan terms, or make credit decisions. Any application, approval, rates, fees, repayment terms, and funding timing are determined by the independent third-party provider you choose. Important note Up to $900 is subject to eligibility and provider requirements. Rates, fees, and terms vary by provider and state. Some details may be shown as estimates until you complete a provider’s application. Annual Percentage Rate (APR) may be up to 35%, depending on your eligibility and the provider’s offer. Repayment terms may range from 3 to 24 months, depending on the option you choose. Payment due dates will be shown by the provider before you finalize an application. Availability varies by location.

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.
