A SIMPLE 4-STEP PROCESS

From AI idea to a live, editable website

  1. 1. Download the knowledge kit

    A free zip of authoring instructions, the schema reference, a ready-to-copy system prompt and an example project.

  2. 2. Generate a project

    Give the kit to an assistant you already use and ask for a .sima package. The kit teaches it the document format.

  3. 3. Import into Sima

    Create a site from the package, or replace the draft of an existing one. Nothing is written until the package passes validation.

  4. 4. Customize and publish

    Pages, components, data and theme are editable in the same editor as any hand-built project. Then publish.

BUILT FOR YOUR CONTROL

Where the AI actually runs

The AI generates your project in an external assistant such as ChatGPT. You then import its .sima file, customize every part and publish with Sima. Your project stays editable.

Sima is independent and is not affiliated with or endorsed by OpenAI.

HOW IT WORKS

Two steps outside.
Two steps inside.

The first two steps happen in an AI assistant you choose. The last two happen inside Sima.
