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.

Kindle readers have built-in highlight sync. Physical book readers have a highlighter and a problem. Bright Passages solves it. Point your camera at a highlighted passage in a real book. Bright Passages reads the page, transcribes it, and detects what color highlighter you used — automatically categorizing the passage before you tap save. Didn't highlight it? Just select the text by hand instead — perfect for library books, textbooks, or any page you didn't mark up. Your highlights become a searchable, shareable library in seconds. Finally, an app built for people who read physical books. Bright Passages is a digital commonplace book — the tradition of collecting passages from real pages that move, challenge, or clarify your thinking. Highlight detection that thinks with you. Bright Passages' camera detects six highlighter colors — orange, yellow, pink, blue, green, and purple — and maps them to your personal categories, renamed however you like. Answer one quick question when you first open the app — student, book club, fiction, nonfiction, or religious study — and your categories are already set up to match how you actually read. The colors you already use in the margins now mean something in your library too. Capture the highlighted words alone, or the full page with the marked passage bolded, italicized, or both. Need more than one page for a single passage? Take multiple photos and combine them into a single capture. One category system, two levels of control. Set your categories globally, then override them book by book — so "Quote" in one book can mean "Premise" in another, without changing anything else. Add your own thinking. After capturing a passage, add a note — your reaction, a connection you made, a question it raised. Edit any transcription with a built-in formatting toolbar for bold, italic, underline, and undo. Notes are saved alongside the passage and included in every export. Your physical library, finally organized. Every passage lives inside its book. Add a chapter number for citation-ready passages. Filter by chapter, category, or reading status. Search across every physical book you've ever read. Share a passage as a beautiful card. Export your library as CSV, Excel (formatting preserved), or Markdown. Your data is always yours. No subscription. No account. No cloud you don't control. One purchase. Your data syncs through your own iCloud — private, automatic, no third-party servers. The words you've marked in real books deserve better than another monthly fee.

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.
