    Transform Any Prompt Into a Better One — On Your Device, Instantly
    
    Stop sending weak prompts. Prompt Enhancer rewrites your rough ideas into clear, detailed instructions using Chrome's built-in Gemini Nano AI — no servers, no subscriptions, no data ever leaves your machine.
    
    KEY FEATURES
    
    ★ Instant Enhance
    Click the floating icon button or press Ctrl+Shift+E to rewrite your prompt on the spot. Results stream in real-time, token by token, just like the AI platforms themselves.
    
    ★ Add Context Mode
    Press Ctrl+Shift+D to open a guided conversation. The AI asks clarifying questions about your intent and keeps asking until it has what it needs then crafts a prompt tailored to your exact situation. Each browser tab runs its own independent session, so multiple tabs never interfere with each other.
    
    ★ Native Editor Insert
    Push the enhanced prompt directly into the platform's input field with one click. No copy-pasting. The extension integrates with each platform's actual editor — ChatGPT, Gemini, Claude and Perplexity all work natively, including activating the send button automatically.
    
    ★ Regenerate
    Not quite right? Hit Regenerate for another take. In Context Mode, your full conversation history is preserved so each attempt builds on what came before.
    
    ★ 100% Private & Offline
    All processing runs on your device using Chrome's built-in AI. Your prompts never leave your computer. No accounts. No cloud. No exceptions.
    
    ★ Prompt History
    Your 20 most recent enhanced prompts are one click away in the popup — click any to copy instantly. Prompts are only saved when you choose to Copy or Insert, never automatically.
    
    ★ Dark & Light Themes
    Toggle themes from the popup. Syncs everywhere in real-time.
