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.

Red Crow transforms YouTube in Safari. Hide Shorts completely, skip sponsors, control playback speed, and reshape the whole page with more than 150 settings. Works on iPhone, iPad, and Mac. HOW IT WORKS Install the extension, open any video, and everything works automatically with sensible defaults. Open the settings panel right on the page to customize every detail, or use quick presets to apply popular configurations in one click. KEY FEATURES - Play, pause, and skip tracks in YouTube Music using compatible headphones in Safari on Mac. - Hide Shorts, everywhere: the sidebar link, the Shorts tab, home feed shelves, and Shorts that turn up in search results. Not collapsed, gone. - Or convert them: open any Short in the normal video player instead, with a real progress bar and your usual speed controls. - Custom playback speed: set any default speed from 0.25x to 16x, with per-channel memory. - Quality control: force a default quality and a separate fullscreen quality. - SponsorBlock: automatically skip sponsors, intros, outros, and other non-content segments. - DeArrow: replace clickbait titles and thumbnails with community-sourced alternatives. - Return of dislikes: restore dislike counts and the like/dislike ratio bar. - Theater and cinema mode: auto-enter theater mode, dim the page background, or go fully cinematic. - Hide other distractions: comments, related videos, mixes, end cards, upcoming videos, premieres, and more. - Block channels and keywords: filter out any creator or title you never want to see, everywhere they appear. - Dim or hide videos you have already watched. - Duration filter: hide videos shorter or longer than your preferred range. - Player toolbar: screenshot, loop, A-B loop, timestamp bookmarks, picture-in-picture, pop-out player, reverse and shuffle playlists. - Video filters: adjust brightness, contrast, saturation, sharpness, blur, hue, and more in real time. - Audio-only mode: keep listening without the video. - Playlist duration: see the total and remaining time for any playlist. - Chapter navigation: a slide-out panel showing all chapters for quick seeking. - Auto-translate titles into your language, and open transcripts automatically. - Comment search: find any comment on a video. - Chat emotes: 7TV, BetterTTV, and FrankerFaceZ emotes in live chat. - Codec control: block VP9, AV1, or high frame rate to save battery and CPU. - Channel profiles: save per-channel settings for speed, quality, volume, and cinema mode. - Custom themes: Nord, Solarized Dark, Catppuccin Mocha, or force the site's own light or dark theme. - Mini-player: a floating mini-player that follows you as you scroll down the page. - Scroll volume: change volume by scrolling over the player. - Usage timer: get reminded to take a break after a configurable watch time. - Keyboard shortcuts: customizable shortcuts for loop, screenshot, PiP, cinema, and more. - Channel RSS: subscribe to any channel in your own feed reader. - Presets: one-click configurations for Podcast, Presentation, Music, Minimal, and Focus modes. - Custom CSS: inject your own styles for complete visual control. SETTINGS AND CUSTOMIZATION The full settings panel opens right on the page, organized into clear sections with a search bar and setting descriptions. Import, export, or reset your configuration at any time. PRIVACY FIRST Red Crow does not collect, store, or transmit any personal data. It runs entirely on your device with no analytics, no tracking, and no accounts required. Community lookups for SponsorBlock never reveal which video you are watching.

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.
