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.

Kloak hides faces in your videos — on your device, in your control. No uploads. No servers. No traces. Pick a video, pick an effect, share with confidence. Whether you're a creator protecting bystanders, a parent sharing family clips, a journalist shielding sources, or just someone who cares who's recognizable in your footage, Kloak makes face redaction fast, flexible, and honest. — PRIVACY-GRADE BY DEFAULT — Most "blur" tools can be reversed by AI face-restoration models. Kloak labels every effect clearly. Privacy-grade effects — Mosaic, Pixelate, Bloom, and Emoji — irreversibly destroy face pixels so they stay hidden. Stylistic effects (like Gaussian blur) are tagged so you know exactly what protects you and what just looks nice. — PER-PERSON CONTROL — Kloak auto-detects every face in your video. Tap any person to apply a specific effect, leave them visible, or swap their face for an emoji. Different effects for different people in the same clip — your call, every time. — FEATURES — • Auto face detection across the full timeline • Mosaic, Pixelate, Bloom — irreversible privacy-grade effects • Emoji overlays • Gaussian blur for stylistic softening • Freeform drawing tool for custom regions • Live preview before you commit • Quick actions • Re-open and re-edit any processed video later • Real-time progress with time estimates — ON-DEVICE, ALWAYS — Every frame is processed locally on your iPhone. Your videos never leave your device. No account, no cloud, no telemetry, no network required. Made for people who believe consent matters in video.

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.
