Writing a good prompt means juggling placeholders, formatting, variables, and rewrites — all in a tiny chat input box. PromptEditor gives you a proper side panel editor right in your browser. No tab-switching, no copy-pasting. Write, format, fill, share and send — all in one place.

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.
