A product spec, screen plans, and build steps for your coding agent.

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.

Berty makes privacy the easy option. Berty is an encrypted and offline peer-to-peer messenger with NO central server. Connect with or without an internet connection, message for free, and avoid surveillance and censorship. DISCLAIMER: Berty is fresh off the development line and hasn’t been audited yet. Please keep this in mind when exchanging data. END-TO-END ENCRYPTED MESSAGING In some countries, even a lol or a like can get you sent to jail. Berty is end-to-end encrypted - not even our developers could access your data, let alone corporations or governments. 100% DECENTRALIZED Just like blockchain technologies, Berty doesn’t pass your data through central servers - the place where internet service providers, hackers, and governments can intercept your data. Instead, Berty’s network is distributed, based on P2P direct messaging. COMPLETELY ANONYMOUS Berty couldn’t care less about who you are. You don’t need to provide your real name, an email, or a date of birth. You don’t even need a SIM card! PROTECT YOUR METADATA You might not know what metadata is, but WhatsApp, Facebook Messenger, and WeChat all collect it. This data can reveal a lot about you - so you’ll be glad to hear Berty is a messaging app alternative that collects as little metadata as humanly possible. COMMUNICATE WITHOUT TRADITIONAL NETWORKS Berty is made to work in the most challenging network conditions in the solar system. If governments, hackers, or natural disasters shut down cellular or internet networks, users can still make vital instant communications over Berty’s proximity Bluetooth feature. JOIN GROUP CHATS Berty is a full-featured instant messaging app. Create groups, chat securely, and share media with friends, family, and colleagues. SHARE VOICE MESSAGES Instantly send encrypted voice memos and audio files on Berty’s decentralized network. FREE FOREVER Privacy is a right for everyone, so Berty doesn’t profit from keeping you safe online. Created by an NGO, Berty will always be free and relies on the generous community to fuel development. TOGGLE BETWEEN ACCOUNTS Create different accounts to split your messaging identities by work, school, family - however, you want to categorize your messages! The Berty messaging app, built on the Berty Protocol, is designed, developed, and deployed by the French non-profit NGO, Berty Technologies. But Berty isn’t just decentralized in terms of its architecture - it’s also owned by the community, not a corporation interested in profits. The progress of Berty relies on developers testing and feeding back on our open source code, generous funding from funds and individual donors, and online and offline advocacy in the community.

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.
