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.

DeArrow is a browser extension for crowdsourcing better titles and thumbnails on YouTube. The goal of DeArrow is to make titles accurate and reduce sensationalism. Titles can be any arbitrary text. Thumbnails are screenshots from specific timestamps in the video. These are user submitted and voted on. By default, if there are no submissions, it will format the original title to the user-specified format, and set a screenshot from a random timestamp as the thumbnail. This can be configured in the options to disable formatting, or show the original thumbnail by default. If the original thumbnail is actually good, you can still vote for it in the submission menu, and then it will act like a submission. No more dealing with clickbait, arrows, or annoying faces. Users can submit better titles and thumbnails for each video and vote on them. How does DeArrow differ from Clickbait Remover for YouTube? - Unlike Clickbait Remover, DeArrow's main purpose is for crowdsourcing better titles and thumbnails - When a crowdsourced title is not available, DeArrow will auto-format it according to your setting, but does it in a more sophisticated way than Clickbait Remover. Instead of only setting all words to lower case, or capitalizing every word, DeArrow supports casing systems such as "Title Case" and "Sentence case". These will still allow acronyms and proper names to remain capitalized. - When a crowdsourced thumbnail is not available, DeArrow by default shows a screenshot at a random timestamp in the video. Clickbait Remover's thumbnails use YouTube auto-generated thumbnails, and while they are seemingly random, they are chosen by a machine learning algorithm to favor faces with expressions, and other overstimulating features. DeArrow uses truly random timestamps generated by its own server. DeArrow will also check the SponsorBlock database to ensure the randomized thumbnail is not inside of a sponsor segment. --- Source code: https://github.com/ajayyy/DeArrow Permissions: Access your data for youtube.com, www.youtube-nocookie.com: - Used to modify the YouTube webpage This add-on may also **ask*" to access data for any website: - You can add your own instances of 3rd party YouTube front-ends, and it will ask for permission to modify each site you add - It will never ask for permission for all sites, only the sites you request - Invidious support is not finished at the moment

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.
