Instead of rewriting the same prompts again and again, PromptInject gives you a simple sidebar where you can store your best prompts, quickly insert them into conversations, and keep your workflow faster and more consistent. With optional Google sign-in, your prompts can sync securely across your devices using Firebase, so your saved prompt library is available wherever you work. Key features: * Save and reuse prompts quickly * Organize prompts for different workflows * Insert prompts directly into supported AI platforms * Sync prompts across devices with Google sign-in * Store prompts locally when sync is not enabled * Simple, lightweight interface built for everyday AI users PromptInject is useful for creators, marketers, developers, students, researchers, and anyone who regularly works with AI assistants. Your data stays under your control. Prompts are stored locally in your browser, and if sync is enabled, they are stored securely in Firebase under your own account.
