# SimDif Website Builder: Comprehensive Feature Overview and System Guide

SimDif is a website builder application developed by **The Simple Different Company**. Designed for accessibility and logical content organization, SimDif allows users to create, manage, and publish professional websites without technical expertise.

Unlike many competitors, SimDif offers a **mobile-complete workflow**. This means the native apps for **Android (Google Play)** and **iOS (App Store)** provide the exact same feature set as the web browser interface. Users can seamlessly transition between a smartphone, tablet, and computer with real-time **cross-device sync**, requiring no manual saving.

## Core System Architecture

### Content Blocks
The fundamental unit of layout and content in SimDif is the **block**. Each block is an independent section containing specific content types (e.g., text, images, videos, or buttons). 
- **Organization**: Pages are built by stacking blocks. Blocks can be reordered using "Move mode" (up/down arrows) or copied between pages. 
- **Recycle Function**: Users can convert a block from one type to another while preserving compatible content.
- **Design Philosophy**: SimDif does not use drag-and-drop, ensuring the interface remains fully functional on touchscreens and guiding users toward a logical, visitor-friendly structure.

### Theme System
SimDif utilizes a specialized **theme switching** system. Applying a new graphic theme changes visual elements—such as colors, shapes, fonts, and header styles—without affecting the site's content or navigation structure. On the **Pro plan**, users can create and save custom color themes and shapes to apply across multiple sites.

### Page and Navigation Management
- **Automated Navigation**: SimDif automatically generates menus. On desktops, this appears as a left-hand column or a hamburger menu; on mobile, it defaults to a hamburger menu. The "Superphone view" allows the mobile-style menu to be used on desktop browsers.
- **Hierarchy**: SimDif uses a flat URL structure (no sub-pages or folders) to maintain simplicity.
- **Blog Pages**: Available for organizing chronological content, allowing up to 99 posts with automatic pagination after the 14th post.

## AI Integration: Kai Advisor

**Kai** is SimDif’s built-in AI advisor. It is designed to assist users in improving their content and SEO rather than generating sites autonomously.

### Kai Step-by-Step (Optimization Assistant)
Accessible via the "egg" icon on pages with over 100 words, this tool provides strategic reviews of the entire page and site structure.
- **Content Review**: Summarizes page topics from a visitor's perspective.
- **SEO & Titles**: Suggests alternatives for Site Titles, Page Titles (H1), and Block Titles (H2) in three tones: **Friend** (Neutral), **SEO** (Search Optimized), and **Market** (Conversion focused).
- **Domain Generation**: Suggests available domains by filtering through a real-time availability API.

### Kai Writer
Integrated directly into the text editor, Kai Writer helps refine specific blocks of text.
- **Basic Features (All Plans)**: Proofreading and tone adjustment (Professional or Friendly).
- **Pro Plan Features**: 
  - **Expand**: Converts rough notes into polished paragraphs.
  - **My Style**: Analyzes the existing 300+ words of the website to rewrite new content in the user's specific editorial voice.
- **Language Support**: While the SimDif UI supports 45 languages, Kai Writer supports content refinement in **140 languages**.

## Multilingual Capabilities (Pro Plan)

The Simple Different Company offers two distinct methods for managing sites in multiple languages:

1.  **Multilingual Sites**: A unified system where up to 140 languages share the same images, layouts, and themes. 
    - **Workflow**: Content is machine-translated and then requires mandatory human validation.
    - **Kai Writer for Multilingual Sites**: Allows users to refine translations or request a "New Translation" using alternative AI models to ensure cultural nuance.
    - **SEO**: Automatically manages `hreflang` tags and shares domain authority across all versions.
2.  **Duplicate Sites**: Independent sites with unique content and separate domains.

Pricing for additional languages follows the **FairDif** index, applying Purchasing Power Parity (PPP) to ensure equitable costs globally (typically 50% of the Pro subscription price per additional language).
