From idea to live in four stops.

The same line you follow in the panel. The blue dot is where your product is right now.

  1. 1 · Idea

    You describe

    How the business works today and what gives you headaches.

  2. 2 · Planning

    AI draws the plan

    Screens, rules and steps. When it assumes something for you, it tells you.

  3. 3 · Building

    Agents build and test

    Every part is tested on its own before it reaches you.

You're in charge. No code knowledge needed.

Once the system is live, it keeps evolving. In the panel you see what's being built, what's already delivered and what's waiting for your decision.

  • Only calls you when neededOne question at a time, in plain language. Everything else stays quiet.
  • AI suggests improvementsIt watches usage and proposes the next step. You decide if it goes in.
  • Everything is yours and reversibleEvery change is recorded and can be undone. Code and access are yours.

One plan. Credits to build.

How far does a credit go?

Common questions.

Do I need to understand technology?

No. You explain what you need in your own words. When something is missing, the AI asks, one thing at a time.

Can I reuse the spreadsheet I already have?

Yes. It can be the starting point: the same data becomes records, statuses and reports inside the system.

Can I start with just one part?

You can, and it's what we recommend. Start with what takes the most work today, like orders or scheduling. Each new part is a separate request, with its credit cost shown before you approve.

Is someone coding behind the scenes?

No. A pipeline of AI agents plans, builds, tests and publishes. That's why it's ready so fast and fits a monthly plan.

How long does it take?

The first version of a new product takes a few hours. After that, each improvement you approve joins the queue and goes live when it's ready.

What if I don't like the result?

You see every delivery before it counts. Ask for a change in the panel, or undo it. And in the first month you can cancel and pay nothing.

What happens when the credits run out?

The system stays live. New builds wait for next month, or you buy a one-off pack whenever you want.

Is the system mine?

Yes. The code, the data and the access are yours. Everything is recorded, and you can take it to another team whenever you want.
