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.

Evernote is your second brain — the place to keep everything that matters and find it again the moment you need it. "…an invaluable tool for organizing a messy digital life." — The New York Times Capture a thought, a to-do, a photo, or a whole project, then let Evernote help you organize it, make sense of it, transcribe a meeting or tidy up a rough draft, and bring it back exactly when it counts. From the first spark of an idea to the finished plan, it all lives in one calm, searchable place — at work, at home, and everywhere in between. CAPTURE ANYTHING Jot a quick note, build a checklist, save a photo, an email or a PDF, or clip an article from the web before it disappears. Type it out, write by hand, snap a picture, or record a voice memo — whatever's fastest in the moment. Your ideas land in one place, ready when you are, so nothing gets lost on a sticky note or buried in your inbox. STAY ORGANIZED, EFFORTLESSLY Sort notes into notebooks and add tags, or just start writing and let structure follow. Group related notes together, pin the ones you reach for most, and keep work, school, and life neatly apart — without spending your day tidying up. Evernote keeps things in order so you can stay focused on the thinking. FIND WHAT YOU NEED, FAST Search across everything you've saved — including the text inside your images and PDFs. Ask in plain language and Semantic Search surfaces the right note, even when you can't remember the exact words or where you put it. The more you save, the more useful it becomes. MEET YOUR AI ASSISTANT Your AI Assistant clears away the busywork so you can stay in the thinking, working quietly alongside you. Record a conversation and Evernote AI transcribes and summarizes it for you; AI Transcription turns audio, images, and video into text; and AI Edit cleans up a rough draft, shortens it, or changes the tone while keeping it in your own voice. PLAN YOUR DAY Add due dates, reminders, and to-dos right inside your notes, so the next step is always clear and nothing slips through the cracks. Check things off as you go and keep momentum without switching apps. WORK EVERYWHERE Your notes sync automatically across iPhone, iPad, Mac, Windows, and the web — start on one device and pick up right where you left off on another. Evernote works offline too, so you're never locked out of your own ideas, even when you're far from a signal. FOR WORK, SCHOOL, AND LIFE - Plan projects, prep meetings, and keep every detail in one place. - Take lecture notes, organize research, and study smarter for exams. - Save recipes, plan trips, track goals, and remember the little things that matter. - Keep a journal, draft your next big idea, and capture inspiration whenever it strikes. "Its magic lies in its flexibility." — PCMag However you think, and whatever you're working on, Evernote helps you remember everything and get it done. Capture today's idea — and find it the moment you need it.

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.
