From rough idea to build-ready AI app brief

Turn a half-baked idea into an AI-ready build bundle.

NabuKit takes a one-line app idea and turns it into the brief your AI coder actually needs: research, PRD, design direction, mockups, and a copy-paste build prompt.

Or skip the blank brief

Start from an app brief that’s already built — browse the marketplace and clone a blueprint into your account.

Hand-built blueprints for common app categories: the product angle, scope, mockups, and build prompt. Clone one, make it yours, and hand it to Claude Code, Cursor, Codex, Lovable, Bolt, or a human dev.

Everything you get

One folder. Every answer.

  1. 01

    A research-backed app brief

    Market, user, business, product, and brand choices get written down in short pages your builder can read before it touches the code.

  2. 02

    Visual direction, not vague taste

    Real screen sketches travel with the brief as the visual contract. Draw a screen by hand and it becomes part of the bundle.

  3. 03

    A prompt package any AI builder can read

    A downloadable artifact folder plus a copy-paste build prompt — made for Claude Code, Codex, Cursor, and the next tool you try.

  4. 04

    Change the brief in plain words

    Chat, a content panel, a wizard, or plain text all edit the same source of truth. Every file keeps its full history.

  5. 05

    Yours to keep

    Your own AI key, your data, your build bundle. Download it and walk away clean any time — no lock-in, no ceremony.

A look inside

See the brief your AI builder reads before it writes the first file.

No setup, no jargon, nothing to install. You answer plain questions; NabuKit turns them into a tidy brief you can read, change, and hand off.

  • Screenshot of the projects dashboard listing several projects as tidy cards.

    All in one place

    Every app brief you start lives on one shelf — pick up exactly where you left off, no hunting.

  • Screenshot of the chat panel editing a brief in conversational language.

    Change your mind out loud

    Want it different? Say so in plain words. The brief updates and remembers — no starting over.

  • Screenshot of a single project overview with its planning files.

    Decided once, kept forever

    Every choice is written down a single time, so your AI builder never asks you the same thing twice.

How it works

Three steps. One better first pass.

  1. 1

    Describe the app

    Bring a rough idea — or discover one. NabuKit helps find the market, the users, and the angle worth building.

  2. 2

    Package the brief

    It shapes the research into a build-ready bundle: Brand, Market, Business, PRD, Design, mockups, and images.

  3. 3

    Hand it to the builder

    Give the finished bundle to your AI coder or dev. It starts with context, constraints, screens, and a real finish line.
