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

Your first Build Kit is free with a verified email.
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.

Good fit for mobile-first iOS and Android prototypes with managed app scaffolding.

Talk to GPT, Gemini, Claude, Mistral, Groq, and 200+ AI models in one app — by voice and through Siri, including Siri in CarPlay. Switch providers anytime and stay in control of what is shared. KEY FEATURES • Multi-Provider AI — Use Google Gemini, Anthropic Claude, OpenAI, Mistral, Groq, or OpenRouter (200+ models). Switch anytime. • Siri Integration — Ask Milo anything hands-free, no need to open the app. • Voice-first AI through Siri in CarPlay — brief, driver-safe answers while you drive. • Voice Dictation — Speech-to-text for fast, hands-free chat. • Persistent History — Conversation history is saved locally on your device. • Bring Your Own Keys — API keys are stored securely in iOS Keychain and used only for direct requests to your selected provider. • Clear AI Data Permission — Before cloud AI is used, Milo explains what prompt/context data is sent, identifies the third-party AI providers, and asks for your permission. Milo is built for people who want one place to talk to many AI models — at home, at your desk, or on the road. Note: Cloud AI features require your own API key from at least one supported provider and permission to send prompts/context to that provider. On-device Apple Intelligence, where available, does not send prompts to third-party AI services.

Hypothesis 1
Assumption to check: Users often find AI chat assistants lack contextual understanding.
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Limited customization options for user preferences.
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Navigating between chats can be cumbersome.
Validate with people who use this workflow before building.
Hypothesis 4
Assumption to check: AI responses can be repetitive or generic.
Validate with people who use this workflow before building.
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.
Not assessed in a Build Kit yet.
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.
