Adds an Optimize button on chatgpt.com that opens OpenAI’s GPT-5 Prompt Optimizer with your current prompt. ### 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.
