PromptEditor: Markdown Sidebar for AI Prompts

Stop copy-pasting. Edit AI responses in a Markdown sidebar, fill placeholders, set variables, and send to ChatGPT, Claude & Gemini.

**Stop fighting with copy-paste and small text boxes.** 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. --- **✦ MARKDOWN SIDEBAR — EDIT WITHOUT LEAVING THE CHAT** A lightweight Markdown sidebar (ChatGPT side panel) opens right alongside your AI chat. No new tabs, no copy-pasting to a separate app — just click, edit, and send. **✦ SEND DIRECTLY TO ANY AI CHAT** Finished editing? Click "Send to…" and choose where to send your prompt. PromptEditor opens a new tab and automatically inserts your prompt into ChatGPT, Claude, Gemini, Perplexity, or Copilot — ready to send with one keystroke. The smoothest AI workflow you'll find. **✦ SMART PLACEHOLDER DETECTION** PromptEditor automatically highlights [variables] and {parameters} in your prompt. Click any placeholder to instantly replace it with the real value. A practical prompt engineering tool for anyone building reusable prompt templates. **✦ GLOBAL VARIABLES** Define persistent key→value pairs once (e.g. your name, environment, project context) and PromptEditor will silently auto-fill every matching placeholder whenever a prompt loads. Toggle auto-replace on or off at any time. **✦ LOAD FROM FILE** Open any .txt or .md file directly into the editor with one click. Markdown files render as rich text; plain text files load as-is — ready to edit and send. **✦ FIND & REPLACE** Need to swap a word or phrase throughout your prompt? Open the Find & Replace panel, type what you want to change, and replace one occurrence or all of them at once. **✦ RICH TEXT THAT COPIES AS MARKDOWN** Bold, italic, underline, bullet lists, numbered lists, tables — format your prompt visually. When you click "Copy Prompt", it converts everything to clean Markdown automatically. A true Markdown prompt exporter built into your browser. **✦ PROMPT HISTORY** Every prompt you copy is saved to a local history. Restore any previous prompt with one click, or delete entries you no longer need. **✦ WORKS ON ALL MAJOR AI SITES** - Claude (claude.ai) - ChatGPT (chatgpt.com) - Gemini (gemini.google.com) - Perplexity (perplexity.ai) - Microsoft Copilot (copilot.microsoft.com) **✦ SELECT ANY TEXT** Highlight any text on any of the supported AI sites and a PromptEditor button floats above your selection — send any part of a response to the editor instantly. **✦ PRIVACY FIRST** Zero data leaves your browser. No accounts, no servers, no telemetry. All history and variables are stored locally using Chrome's built-in storage. --- **HOW TO USE** 1. Install PromptEditor and open any AI chat 2.
