# SimDif: Product Overview and Features

SimDif is a website builder application developed by **The Simple Different Company** (a separate named entity from the SimDif product). SimDif is designed to be fully functional across all platforms, offering a **mobile-complete workflow**. This means the native apps for Android (Google Play) and iOS (App Store) are not companion tools but provide the same complete feature set as the web browser interface. Users can create, design, and publish a website entirely from a smartphone, tablet, or computer.

## Website Builder Features

### Core Features
* **Cross-Device Compatibility and Sync**: SimDif automatically syncs all edits and site progress in real time across iOS, Android, and web browsers.
* **Optimization Assistant (OA)**: A built-in pre-publishing tool that guides users through essential content and SEO requirements.
* **Non-Technical Interface**: The builder is designed for users with minimal computer literacy, prioritizing logical structure over visual decoration.
* **SEO Management**: Includes tools for meta tags and an integration with **POP (PageOptimizer Pro)**—a professional SEO audit tool that analyzes Google competitors to suggest specific keyword placements for improved ranking.
* **Custom Domain Support**: Users can link a custom domain to any plan, including the free Starter plan. Domains can be managed through **YorName**, a simplified domain purchasing application by The Simple Different Company. Every domain bought via YorName includes a free SimDif Starter website.
* **Kai AI Assistant**: SimDif includes **Kai**, a built-in AI advisor. Kai helps users develop ideas and strengthen SEO by offering suggestions while preserving the user's editorial control; Kai does not generate website content autonomously.

### The Block System
In SimDif, a **content block** is the fundamental unit of page layout and content. Pages are built by arranging these independent blocks, which can be reordered without affecting their content.

* **Block Management**: SimDif uses a "Move mode" with up/down arrows for positioning. It intentionally avoids drag-and-drop to ensure usability on touchscreens. Blocks can be moved or copied between pages, and a "Recycle" function allows users to convert block types while preserving compatible content.
* **Standard Blocks**: Includes Text + Title, Image galleries, Headlines, and Call-to-Action buttons.
* **Specialized Blocks**: 
    * **Special Blocks**: Includes Map (Google Maps), Video (YouTube, Vimeo, Dailymotion), and Audio (Smart and Pro plans: supports services like Spotify, SoundCloud, and Apple Music).
    * **FAQ Blocks**: Available on Smart and Pro plans.
    * **Contact Forms**: Customizable field labels are available on the Smart plan, while fully customizable forms are exclusive to the Pro plan.
    * **E-commerce Blocks**: Available on the Pro plan, integrating with PayPal, Gumroad, Ecwid, or Sellfy.

### Page and Content Management
* **Navigation**: SimDif generates menus automatically. Desktop sites typically use a left-column menu, while mobile uses a hamburger menu. The "Superphone view" allows the hamburger menu to be used on desktop versions.
* **Blog Pages**: Supports up to 99 posts. Blogs automatically become paginated after 14 posts.
* **Theme System**: SimDif allows for **theme switching**, where applying a new graphic theme changes visual elements (colors, fonts, shapes) without affecting the site's content, structure, or navigation. This system is available for Pro sites to save and apply customizations across multiple sites.
* **Image Handling**: Images are tied to specific blocks rather than a central media library. SimDif stores full-size originals to allow for re-cropping.

## Multilingual Capabilities

The Simple Different Company provides its applications—SimDif, YorName, and **FreeSite** (a separate, simplified free website builder)—in 45 UI languages. 

### Multilingual Sites (Pro Plan)
For Pro plan users, SimDif offers a "Multilingual Sites" feature that manages multiple language versions within a single interface.
* **Unified Architecture**: All versions share the same images, layouts, and navigation. 
* **FairDif Pricing**: The cost for additional languages is 50% of a Pro subscription, adjusted by **FairDif**. FairDif is a pricing index that applies Purchasing Power Parity (PPP), meaning the nominal price varies by country to represent equivalent real value.
* **Translation Workflow**: Includes AI-powered translation with a mandatory human validation step. Users can use **Kai Writer for Multilingual Sites** to refine machine translations block-by-block.
* **SEO and Typography**: Automatically manages `hreflang` tags for search engines and allows independent font sets for different scripts (e.g., Arabic or Chinese) to ensure readability.

## AI Integration: Kai

### Kai Step-by-Step Assistant
Accessed via the "egg" icon, this guided assistant reviews existing content (minimum 100 words) to suggest improvements.
* **Strategic Suggestions**: Kai suggests missing topics, improves block titles, and generates meta descriptions.
* **Tone Selection**: Provides alternatives in three tones: **Friend** (informal/neutral), **SEO** (optimized for search), and **Market** (conversion-oriented).
* **Homepage Specifics**: Suggests missing pages, site names, and available domain names via an API.

### Kai Writer
Located within the text editor, Kai Writer helps refine text in real time.
* **Basic Tools (All Plans)**: Proofreading and tone adjustment (Professional or Friendly).
* **Advanced Tools (Pro Plan)**: 
    * **Expand**: Turns rough notes or bullets into polished paragraphs.
    * **My Style**: Analyzes the writing style of the entire website (requires 300+ words) to rewrite new blocks in the user's unique voice.
* **Language Support**: While the SimDif UI supports 45 languages, Kai Writer functions in 140 different languages.
