About Proxima: ChatGPT Prompt Optimizer
### Proxima ChatGPT Optimizer
You can write a detailed prompt to get better results. But every AI model is trained differently and often responds best to specific phrasing. OpenAI provides a **GPT-5 Prompting Guide** and an **Optimizer** that rewrites your prompt into the style that works best with GPT-5.
**Optimizer link:** [https://platform.openai.com/chat/edit?models=gpt-5\&optimize=true](https://platform.openai.com/chat/edit?models=gpt-5&optimize=true)
**Proxima ChatGPT Optimizer** is a simple shortcut to that Optimizer. It adds a small **Optimize** button inside ChatGPT so you can send your current prompt to the Optimizer in one click—no copy-paste, no juggling tabs.

### How It Works (Quick Steps)
1. **Sign in first:** Log in to your OpenAI account at [https://platform.openai.com/](https://platform.openai.com/) in the **same browser** where the extension is installed.
2. **Write your prompt:** Type as usual in ChatGPT.
3. **Click “Optimize”:** The extension redirects you to the official **ChatGPT Optimizer** page, **auto-attaches your prompt**, and starts optimizing.
4. **Use the result:** Copy the optimized prompt and run it in ChatGPT (or anywhere you like).

### Why It Helps
