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. https://sites.google.com/view/pr...

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.
