One click sends any AI response to your side panel. Fill placeholders, reformat, rewrite — then send directly to any AI chat or copy as clean Markdown. No tab switching.
PromptEditor stays out of your way until you need it. Then it's just a click away.
A button appears below every AI response on Claude, ChatGPT, Gemini, Perplexity, and Copilot. Click it and the side panel opens instantly with the text loaded in.
Placeholders like [topic] and {variable} light up automatically. Click any one to replace it. Bold, italicise, add bullets — format visually, not in raw Markdown.
Hit "Send to…" and your prompt lands directly in Claude, ChatGPT, Gemini, Perplexity, or Copilot — ready to go. Or hit "Copy Prompt" for clean Markdown you can paste anywhere.
Click "Send to…" and choose where to send your prompt. PromptEditor opens the tab and pastes your text in — ready to send with one keystroke.
Define persistent key→value pairs once — your name, project, environment — and PromptEditor silently auto-fills every matching placeholder whenever a prompt loads.
Zero servers, zero accounts. Everything runs in your browser. Your prompts never leave your machine — no telemetry, no tracking, ever.
Automatically highlights [brackets] and {curly} placeholders. Click any one to type the real value inline.
Bold, italic, underline, bullet lists, numbered lists. Edit visually and copy out as perfectly formatted Markdown every time.
Every prompt you copy is saved locally. Restore any past prompt in one click.
Opens alongside your AI chat using Chrome's native Side Panel API. Your conversation stays fully visible.
Converts your formatted text to clean, standard Markdown when you copy — ready for any AI or note tool.
Open any .txt or .md file directly into the editor with one click.
Swap a word or phrase throughout your prompt instantly. Replace one occurrence or all at once — Cmd+H or the toolbar button.
PromptEditor has no backend, no user accounts, and no analytics. Prompt history is stored in Chrome's built-in local storage — only you can access it, and it never leaves your browser.
Free forever. No account needed. Install in 10 seconds and start using it on your next AI chat.
