# SimDif: Comprehensive Website Builder Features and Capabilities

SimDif is a website builder application developed by **The Simple Different Company** (a separate entity from the SimDif product itself). SimDif is distinguished from other website builders by its **mobile-complete workflow**, offering the exact same feature set and user interface across its native Android and iOS apps as well as its web browser interface. This allows users to create, design, and manage professional websites entirely from a smartphone, tablet, or computer with real-time **cross-device sync** and no requirement for manual saving.

## Core Architecture and Design Philosophy

SimDif’s design is guided by an intentional philosophy that prioritizes logical site structure, navigation, and content clarity over visual decoration.

### The Block System
In SimDif, the fundamental unit of page content and layout is the **content block**. Unlike drag-and-drop editors that can be difficult to use on touchscreens, SimDif uses a click-based navigation system and "Move mode" with up/down arrows.
*   **Independence**: Each block holds specific content (text, images, videos, etc.). Blocks are independent and can be reordered or moved between pages without affecting their internal content.
*   **Recycling**: The "Recycle" function allows users to convert one block type into another while preserving compatible content.
*   **Layout Stability**: Content blocks are designed to ensure the website remains legible and visitor-friendly across all device sizes.

### Theme System and Visuals
SimDif employs a unique **theme switching** mechanism. Applying a new graphic theme (colors, shapes, fonts) changes the visual appearance of the site without affecting page content, page structure, or navigation. 
*   **Pro Plan Customization**: Users on the Pro plan can create and save custom themes, editing border weights, shadows, and background textures.
*   **Consistency**: Themes affect only styling, ensuring that the structural integrity of the site is never compromised by visual changes.

## AI-Powered Assistance (Kai)

**Kai** is SimDif’s built-in AI advisor, designed to help users develop their ideas and improve SEO while preserving the user's editorial control. Kai does not generate website content autonomously.

### Kai Step-by-Step
Accessed via the egg icon (on pages with at least 100 words), this strategic assistant reviews the overall page.
*   **Content Analysis**: Summarizes topics and suggests missing content or pages.
*   **Optimization**: Generates alternatives for Page Titles (H1), Block Titles (H2), and Meta Descriptions in three tones: **Friend** (informal), **SEO** (optimized for search), and **Market** (marketing-oriented).
*   **Homepage Specialization**: Offers suggestions for Site Titles, Google Search "Site Names," and domain name availability through an integrated API.

### Kai Writer
Located within the text editor, Kai Writer provides tactical content refinement for individual blocks.
*   **Basic Tools (All Plans)**: Proofreading and tone adjustment (Professional or Friendly).
*   **Pro Plan Exclusive Tools**: 
    *   **Expand**: Converts rough notes or bullets into polished paragraphs.
    *   **My Style**: Analyzes the existing content of the entire website (minimum 300 words required) to rewrite new text in the user's specific voice and brand style.

## Multilingual Capabilities

The Simple Different Company provides its interface and documentation in **45 UI languages**. For the websites themselves, SimDif offers a robust system for managing international content.

### Multilingual Sites (Pro Plan)
This feature allows for a single website to exist in up to 140 languages under a unified domain.
*   **Unified Architecture**: Images, videos, and layouts are shared across all versions, while text is localized.
*   **AI Translation with Human Validation**: Content is initially translated by AI but requires a mandatory human review step. Users can use **Kai Writer for Multilingual Sites** to refine machine translations or request a "New translation" from a different AI model.
*   **Typography**: Users can assign independent font sets for different scripts (e.g., Arabic or Chinese) while maintaining the same graphic theme.
*   **SEO Benefit**: Shared structure and automatically managed `hreflang` tags concentrate search engine authority on a single domain.

## SEO and Domain Management

### Integrated SEO Tools
*   **Optimization Assistant (OA)**: A pre-publishing checklist that ensures essential SEO and content elements are present.
*   **POP (PageOptimizer Pro)**: A professional SEO audit tool integrated into the app. It analyzes Google competitors to provide specific keyword placement recommendations.

### Domain Integration (YorName)
**YorName** is a separate domain management app by The Simple Different Company. Every domain purchased through YorName includes a free SimDif Starter website. Custom domains from YorName can be linked to SimDif websites even on the free **Starter** plan.
