+
+**Perplexity Client** is an Electron-based desktop application that provides a polished interface for interacting with Perplexity's Sonar API. Unlike typical chat interfaces, it exposes advanced API parameters like temperature, top-p, and max tokens, making it ideal for developers who want fine-grained control over their AI interactions while enjoying a beautiful, macOS-inspired UI.

+
+## Features
+
+* **Multiple Sonar Models** with support for Sonar, Sonar Pro, and Sonar Reasoning Pro
+* **Custom Spaces** with save/load functionality for different use cases
+* **API Parameter Controls** including temperature, top-p, and max tokens adjustments
+* **API Debugging Mode** showing full request/response payloads for troubleshooting
+* **Token Usage Tracking** to monitor API consumption and costs
+* **Focus Modes** for specialized tasks like coding, writing, and research
+
+## Prerequisites
+
+* Node.js v16 or higher
+* npm or yarn
+* Perplexity API key
+
+## Installation
+
+```bash
+# Clone the repository
+git clone https://github.com/straight-heart/Perplexity-client-.git
+cd Perplexity-client-
+
+# Install dependencies
+npm install
+
+npm run dev
+```
+
+## Build
+
+Build the application for your platform:
+
+```bash
+npm run build:win    # Windows
+npm run build:mac    # macOS
+npm run build:linux  # Linux
+```
+
+## Configuration
+
+API keys are managed directly within the application:
+
+1. Launch the app and open Settings (gear icon)
+2. In the **API Keys** section, click **Add Key**
+3. Enter your Perplexity API key
+4. The key is stored securely and persists across sessions
+
+For custom system prompts, use the **Spaces** feature to save and switch between different instruction sets.
+
+## Usage
+
+1. **Launch**: Run `npm run dev` or use the built application
+2. **Add API Key**: Open Settings and add your Perplexity API key
+3. **Select Model**: Use the dropdown to choose between Sonar variants
+4. **Create Spaces**: Set up custom system prompts for different tasks
+5. **Chat**: Start conversing with real-time streaming responses
+6. **Debug**: Enable API debugging to see full request/response details
+7. **Track Usage**: Monitor token consumption in the Settings panel
