§AI Builder Toolkit
For builders shipping with AI

Vibe coding with direction and method.

AI builds fast — in every direction at once. The kit gives it direction and method: 15 years of design, engineering, and UX packed into templates, guides, and principles. What ships is real product, not AI slop.

§ This page was built with this kit

§AI SLOPREAL PRODUCT
The problem

Speed without direction
only ships AI slop.

A pretty demo that breaks on the first real user. Three ways people find that out the hard way:

01

Looks AI-made

Every AI builds the same screens. A serious client, an investor, a hackathon judge — they spot AI slop from across the room.

02

Breaks on the first user

Works in the demo, dies at 10 visits. Real engineering isn't the default the AI learned on its own.

03

Wrong stack to scale

AI picks what it saw most on forums. When your product grows, you find out you're in the wrong place — and rewrite from scratch.

The solution

Direction that points the product. Method that builds the product.

Calibrated templates

Two Next.js starters ready for the AI to clone. Design system, typography, spacing, motion — every visual decision already made and documented.

Guides that give direction

Ten documents the AI reads before each decision — architecture, security, UX, voice. It consults; it doesn't guess.

Principles that last

A stack that actually scales (Next.js + Supabase + Stripe). Grows without rewriting — because it was chosen to last, not to demo.

Who it’s for

For builders shipping with AI. And for the just-starting.

If you see yourself in any of these, the kit was built with you in mind. Not all of them — just one.

§ VIBE

Vibe coder

You describe, the AI builds. The kit gives it direction to build a real product that holds up to users — not just a pretty demo.

§ FOUNDER

Startup founder

Validating an idea or building an MVP. Ship on a base that scales — no rewrite when the product starts working.

§ PM

Product builder / PM

Prototype with the feel of a product, not a mockup. Show stakeholders something that works, not just something that looks.

§ HACKATHON

Hackathon builder

An MVP that wins the demo and still runs the next day. AI builds it fast, the kit makes sure it runs when the judge clicks.

§ DEV

Experienced dev

Skip the setup and get the quality bar for free. You still write code — you just stop writing boilerplate.

§ SOLOPRENEUR

Solopreneur / indie

Building alone, no team. The kit plays the tech lead you don't have — making the 200 boring choices so you can focus on what's yours.

How it works

You set direction.
The AI follows the method.

01step

Clone and run

A starter ready to go on your machine in minutes. Zero configuration.

npx create-ai-builder-toolkit@latest my-app
02step

Set direction

Point your AI at the kit rules. Works with Claude Code, Codex, Antigravity, and Cursor — one sentence and it starts building to the standard.

> read CLAUDE.md before coding
03step

Ship by method

Describe what you want. The AI builds, consulting the guides before each decision. You watch it work and ship.

> build the pricing page using the design system
What's inside

Two starters. Ten documents.
Direction and method.

Not boilerplate. It's 200 professional decisions packaged as code for the AI to clone and as guides it consults before each decision.

The starters02 · ready to clone

app-starter

app · local-first

App base ready for the AI to clone: login, data, dashboard. Starts local, migrates to Supabase when you grow — without rewriting. Light/dark theme, calibrated components, AI scaffold, and Stripe.

website-starter

site · SSR

Site base ready for the AI to clone: landing, marketing, portfolio. Server-rendered — Google and ChatGPT can read it directly. SEO and GEO out of the box, calibrated motion, reusable sections.

README.md is the index. Each document covers a layer of the product, and the links show what depends on what.

The documents10 · rules the AI follows
  • CLAUDE.mdEngineering: architecture, data, deploy.
  • DESIGN.mdDesign and UX: accessibility, motion, anti-slop.
  • DESIGN-SYSTEM.mdYour project's visual identity.
  • COPY.mdVoice, microcopy, and error messages that sound like a human.
  • SECURITY.mdSecurity: XSS, prompt injection, secrets, deploy.
  • AGENTS.mdAI assistants inside the app: sessions, guardrails.
  • PAYMENTS.mdBilling: Stripe, webhooks, idempotency.
  • DATABASE.mdDatabase: schema, migrations, RLS, Dexie → Supabase.
  • WORKFLOW.mdHow to ask, review, and iterate with AI — no coding required.
  • README.mdThe map: setup, index, Supabase migration path.
Why buy

Fifteen years of experience. In one kit.

Every professional decision — design, architecture, security, UX — packaged. Your AI follows; you just build what's yours.

§ EXPERIENCE

Professional rigor, baked in

15 years of decisions made and documented. Your AI inherits that rigor in every file — no guessing, no improvising, no making things up.

§ SPEED

Ship in days

The AI doesn't waste time deciding color, font, or structure — it's all there. You get the whole sprint to build what differentiates you.

§ ECONOMY

Spend less on AI

The AI starts from the right pattern. Fewer prompts on the basics, more on what is actually yours.

§ DESIGN

Looks like a real product

Typography, color, spacing, and motion calibrated before the first pixel. Serious clients can't tell it was generated by AI.

§ ARCHITECTURE

Grows without a rewrite

Abstracted data layer, security applied, payments scaffolded. From the first screen to the first million users, same base.

§ UPDATES

Always up to date

The kit evolves with the stack. Each update sharpens the standard your AI follows — you're not stuck on the version you bought.

To be clear

What this kit is not .

You've been burned by easy promises before. So let's be direct.

Not magic

You still build. The kit gives direction and method — it doesn't replace you or hand you a finished app.

Doesn't test for you

Worked on your machine? Good. Held up to a real user? You need to make sure. The kit gives you the right base for it.

Devs benefit too

Experienced devs skip the setup and get the quality standard — for free.

§ Proof

So real this page was built with the kit itself.

Every section, every component, the login, the checkout, the chat — all from the same base you buy.

Frequently asked

Before you ask.

Still have doubts? Send a note to mail@aibuilderkit.io.

  • No. You set direction in plain English, the AI follows the kit's method, and WORKFLOW.md walks you step by step from clone to deploy. Even without writing a line of code, you can ship.

  • Claude Code, Codex, Antigravity, and Cursor. Calibrated for Claude Code — where the AI follows the guides most faithfully.

  • Yes. No royalties, no restrictive license. What you build with it is entirely yours — including reselling the product that comes out of it.

  • A simple site ships in hours. An app with auth and data, in a few days. The kit cuts the whole setup and gives the AI direction to follow — you keep the entire sprint to build what differentiates you.

  • Next.js + TypeScript + Tailwind. Dexie to start, Supabase when you grow. Stripe for payments. Geist for type. A stack every AI knows — and that scales without swapping.

  • The base is ready for Supabase and payments. The data layer is abstracted — migrating is swapping the implementation, not rewriting the app.

  • No. It brings best practices and steers you away from the common pitfalls (XSS, prompt injection, secrets on the client). But what you build on top is your responsibility — see the disclaimer below.

  • The guide (WORKFLOW.md) covers everything from clone to deploy. If you still get stuck, the AI itself — pointed at the kit rules — gets you out of most dead ends.

  • Yes, free forever — within the scope of the kit you bought. Fixes, polish, and new versions of the current starters and documents show up in My account at no cost. If we later ship a brand-new kit with different boilerplates or new documents, that's a separate product — your version stays yours, but the new one is sold separately.

  • Yes. Email mail@aibuilderkit.io describing your question. It covers the kit itself: usage, document questions, download or login issues. It doesn't cover building your project for you — for that, your AI pointed at the kit's rules is your pair.
