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.

Markview is a private Markdown reader and document workspace for iPhone and iPad. Bring your notes, docs, project wikis, and READMEs into one calm library—or connect an existing folder from Files without copying it. Everything Markview does with your documents happens on device. Rich rendering, done right • Syntax-highlighted code blocks • GitHub-flavored tables and task lists • LaTeX math (KaTeX) • Mermaid diagrams All rendered on-device, with no remote renderer and no executable MDX, R, or Quarto code. Read and return • Continue Reading remembers your position and progress • Fast full-text search with highlighted results • Premium Paper, Sepia, Midnight, Glass Light, and Glass Dark themes • Dynamic Type, VoiceOver, and iPad multitasking support Build a local document wiki • Open a folder from Files as a library without copying it • Follow relative document links, headings, and local images • Back and forward history plus automatic backlinks • Clear reconnect, read-only, and external-change handling Export what you see • Searchable rendered PDF, with a print-friendly Paper default • Self-contained, sanitized offline HTML with embedded local images • Share the original source file at any time Ask this Document—on device • Ask one focused question about the open Markdown-family document • Always see the supporting source passages • Tappable citations return to the exact rendered evidence • Apple’s on-device model enhances answers when available; lexical passage search remains useful when it is not • No question, answer, or transcript history is stored Organize your way • Folders, tags, favorites, and recents • Import from Files or open Markdown from any app • Light editing, rename, move, and source-aware conflict recovery More Markdown-family formats Open .md, .markdown, .mdown, .mkd, .mdx, .rmd, and .qmd. Preview-oriented formats stay inert: Markview displays their text and never executes components, directives, or code. Private by design No account. No advertising. No analytics. No tracking. No Markview server. Markview never uploads documents or Ask content. A folder you select may still be stored or synced by its own Files provider, and Apple manages any optional on-device language-model assets through system settings.

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.

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.
