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.

Captiono: The Ultimate AI-Powered Automatic Subtitle Tool Captiono is a powerful tool for generating automatic video subtitles using artificial intelligence. With Captiono, you can create synchronized subtitles for any language with just a few taps. Creating subtitles for videos has always been a difficult and time-consuming task. But now, with the Captiono app, you can create subtitles for your videos in less than 20 seconds with a few simple steps and share your videos with subtitles on social media. Why should all videos have subtitles? 1. Social Responsibility for the Disabled and Hearing Impaired: By using subtitles for videos, you can fulfill your social responsibility towards the disabled and hearing impaired. Respecting the disabled, having videos with subtitles is becoming a necessity on social media. 2. Significantly Increase Video Views: Many people watch videos in public places. If your video does not have subtitles, people in these places will skip your video, reducing your watch time, and eventually, your posts on various networks like Instagram, TikTok, YouTube, etc., will drop out of the algorithm, causing your page to suffer a significant drop.

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.
