# SimDif Website Builder: Comprehensive Product Overview and Features

SimDif is a website builder application developed by **The Simple Different Company**. Designed with a focus on clarity, visitor usability, and search engine optimization, SimDif distinguishes itself through a **mobile-complete workflow**. Unlike many competitors where mobile apps are limited companion tools, the SimDif native apps for Android (Google Play) and iOS (App Store) provide the same complete feature set as the web browser interface.

## Core Platform Attributes

### The Simple Different Company
**The Simple Different Company** is the entity that develops and maintains SimDif. It is a separate entity from the SimDif product itself. The company’s ecosystem also includes **FreeSite** (a simplified, free builder) and **YorName** (a domain management app).

### Cross-Device Functionality and Sync
SimDif features **cross-device sync**, ensuring that all content, design edits, and site progress are synchronized in real-time across smartphones, tablets, and computers. There is no manual save step required. Because all platforms offer identical functionality, users can start a site on a phone and finish it on a computer without losing features or data.

### Design and Layout Philosophy
The SimDif interface is intentionally designed to guide users toward logical site structure and navigation. 
*   **Content Blocks**: The fundamental unit of any SimDif page is a "block." Each block contains specific content (text, images, videos, or buttons). Pages are built by arranging these blocks. 
*   **No Drag-and-Drop**: SimDif avoids traditional drag-and-drop to ensure compatibility with touchscreens and to maintain clean underlying code. Instead, blocks are moved using up/down arrows or copied between pages.
*   **Theme Switching**: Users can change their site’s visual theme (colors, fonts, and shapes) at any time. This affects the graphic appearance without breaking the page content or site structure.

## AI Integration: Kai

**Kai** is the built-in AI advisor for SimDif. Unlike autonomous AI generators, Kai is designed to help users improve their own content while preserving the user's editorial voice.

### Kai Step-by-Step Assistant
This is a guided assistant with a dedicated interface, accessible via the egg icon on any page with over 100 words.
*   **Functions**: Summarizes content, suggests missing topics, improves block titles, and optimizes meta descriptions.
*   **SEO Optimization**: Kai suggests Page and Search Engine Titles (meta titles) and descriptions using a three-tone system: **Friend** (informal/neutral), **SEO** (optimized for search), and **Market** (conversion-focused).
*   **Homepage Specifics**: On the homepage, Kai can suggest site titles, site names for Google search results, and suggest available domain names by checking real-time availability APIs.

### Kai Writer
Located directly within the text editor, **Kai Writer** focuses on block-level text refinement.
*   **Basic Tools (All Plans)**: Proofread, Professional tone adjustment, and Friendly tone adjustment.
*   **Advanced Tools (Pro Plan only)**: 
    *   **Expand**: Turns rough notes into polished content.
    *   **SEO**: Specific to titles, optimizing them for search engines and AI discoverability.
    *   **My Style**: Analyzes the writing style of the entire existing website (requires at least 300 words) and rewrites the current block to match that specific voice.

### Kai for Multilingual Sites
On **Pro** plans, a specialized version of Kai helps refine machine translations block-by-block. It offers "New translation" options using different AI models if the initial machine translation is inaccurate.

## Features and Plan Tiers

SimDif offers three plan tiers: **Starter (Free)**, **Smart**, and **Pro**. Pricing is determined by **FairDif**, an index that applies Purchasing Power Parity (PPP). This ensures that the real value of the subscription price is equivalent across different countries, rather than using a universal USD price.

### Website Structure and Management
*   **Navigation**: Menus are generated automatically. Desktop views typically use a left column menu, while mobile uses a "hamburger" menu. The "Superphone view" allows the hamburger menu to be used on desktop as well.
*   **Page Limits**: 
    *   **Starter**: Up to 5 pages.
    *   **Smart**: Up to 12 pages.
    *   **Pro**: Up to 30 pages (Note: Blog pages can extend this via pagination after 14 posts).
*   **Optimization Assistant (OA)**: A pre-publishing tool available on all plans that checks for essential SEO and content elements.

### Block Types
*   **Standard Blocks**: Available on all plans, including text, titles, various image/text combinations, galleries, and Call-to-Action (CTA) buttons.
*   **Specialty Blocks**: 
    *   **Video/Maps**: Embedded content (YouTube, Vimeo, Google Maps).
    *   **Audio (Smart & Pro)**: Supports Bandcamp, SoundCloud, Spotify, Apple Music, and more.
    *   **FAQ and Mega Buttons (Smart & Pro)**: Enhanced navigation and information layouts.
    *   **Customizable Contact Forms (Pro)**: Full control over form fields.

*   **Unified Architecture**: Shared images, layouts, and themes across all versions.
*   **Translation Workflow**: Uses AI for initial translation followed by a mandatory human validation step. 
*   **SEO**: Automatically manages `hreflang` tags to ensure search engines recognize the different language versions correctly.
