PromptEditor adds an "Edit in PromptEditor" button to every AI response on ChatGPT, Claude, Gemini, Perplexity, and Copilot. One click sends the response into a Markdown sidebar where you can refine, fill placeholders, and send it directly back to any AI chat — without ever leaving the page.
I got tired of constantly struggling with copy-paste and cramped text boxes when working with complex prompts, so I decided to build my own PromptEditor—designed to make writing and editing prompts much easier.
One of the most valuable features I added is placeholder detection. It saves a huge amount of time when working with reusable prompts by automatically identifying and organizing variables.
The sidebar has become an essential part of my workflow. It’s always open in my browser—not just for editing prompts, but also as a flexible note-taking panel where I can capture ideas for future prompts and instantly send them to any AI chat with a single click.
