## Description

GPT Handbook is a productivity tool for organizing prompts, applying them quickly, and chatting with AI. You can save frequently used prompts, create your own prompt notes, and send prompts directly into a dedicated chat tab.  
  
The rebuilt version uses a modern interface with separate Prompt Library and Chat tabs, making each workflow clearer. It also keeps local chat history so you can return to previous conversations when needed.  
  
Key features:  
  
1\. Built-in prompt templates for learning, work, coding, writing, and everyday tasks.  
2\. Custom prompt support with editing, categories, and tags.  
3\. Copy, share, open ChatGPT/Gemini, or send a prompt directly to the built-in chat tab.  
4\. Built-in AI chat with local chat history and conversation management.  
5\. OpenAI and Gemini support with a common model selector and custom model ID input.  
6\. No default API key is included. To use AI chat, enter your own API key.  
7\. API keys are encrypted and stored locally on your device. They are not included in the app's default setup, and they are not uploaded to the cloud or sent back to any app server.  
8\. Traditional Chinese and English interface switching.  
  
Important notes:  
  
GPT Handbook is not an official product of OpenAI, Google, or Gemini. Using OpenAI, Gemini, or other third-party APIs may incur costs according to each provider's rules. Please review your API key, selected model, and usage settings before using the chat features.
