    **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 & MARKDOWN EXPORT**
    Bold, italic, underline, bullet lists, numbered lists, tables — format your prompt visually. When you're ready, click "Copy Prompt" to copy clean Markdown to your clipboard, or use the "Download as .md" button to export your prompt as a file instantly.
    
    **✦ 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. Click the "Edit in PromptEditor" button that appears below any AI response
    3. Edit the text in the side panel — fill in placeholders, reformat, rewrite
    4. Click "Send to…" to open your prompt directly in any AI chat, or "Copy Prompt" to copy as clean Markdown
    5. Your prompt is ready to go
