Stop losing your best AI prompts. PromptInjector is a secure, freemium Chrome Extension that injects your saved prompts instantly into ChatGPT, Claude, and Gemini with a simple hotkey.

Hey Product Hunt! 👋 I’m Saurabh, the maker of Prompt Injector. Like many of you, I use ChatGPT and Claude every day. But I realized I was wasting so much time switching tabs, digging through Notion/Google Docs, and copy-pasting my most-used prompts. It completely broke my flow. So, I built Prompt Injector. 🚀 It’s a lightweight extension that brings your prompt library directly into the chatbox. Just type / anywhere in ChatGPT, Claude, or Gemini, and your vault opens up. Select your prompt, hit enter, and it’s injected instantly. Key Features: ⚡ Type / to inject instantly 🔒 Free tier runs 100% locally for max privacy ☁️ Cloud sync for Pro users across all devices I built this to solve my own itch, and I’d absolutely love to hear your feedback, roast my design, or tell me what I should build next! Cheers! 🍻

The hotkey injection is genuinely fast and the prompt library syncs between my work and personal laptop without any setup. Surprised how lightweight it feels compared to other prompt managers I've tried.
