Prompt Helper — AI Prompt Improver & Writing Assistant

Write better AI prompts in one click, and rewrite emails, posts & messages anywhere. Works with ChatGPT, Claude & Gemini.

Prompt Helper turns rough ideas into clear, detailed prompts, and polishes the emails, posts and messages you write. Sign in with Google and start in seconds. ⸻ IMPROVE PROMPTS • Paste your idea in the popup and click "Improve prompt" • Choose a mode: Text, Code, Image or Video • Pick a style (default, concise, detailed and more) and copy the result • Works right inside popular AI chats: an "Improve" button appears next to the send button, so you can refine your message before sending • Stays out of the way: it hides while the chat is generating and never covers the site's own controls • Optional conversation context (off by default): Prompt Helper reads your last few messages so short prompts like "make it shorter" make sense REWRITE WHAT YOU WRITE • A small rewrite button appears in email, social and messaging boxes on a handful of popular sites • Tuned to where you are writing: punchy posts, clear emails, friendly chat messages, tidy technical notes • One click, or pick Shorter, Friendlier, More professional or More confident • Undo in one click • Right-click any selected text and choose "Rewrite selection" on any page • Optional rewrite bubble on any site (off by default): turn it on, allow the permission, and a small button appears when you select text • Optional email context (off by default): replies can take the last couple of messages of the thread into account • Nothing is read or sent until you click MORE • Ask tab: ask questions directly in the extension • History: reuse your recent improved prompts • Keyboard shortcut: Ctrl+Shift+E (Windows) or Cmd+Shift+E (Mac) improves your selected text FREE AND PRO • Free: 10 improvements and 5 Ask questions per week, plus limited history • Pro: unlimited improvements, unlimited Ask and full history, from the Pro tab ⸻ HOW IT WORKS 1.
