AI Writing Power, Right Where You Need It

Not anymore. With NotGPT's Chrome Extension, you can transform any text on any website with a simple right-click. Your personalized AI personas are always just one click away, ready to rewrite, improve, or transform your words—instantly.

💡 The Game Changer: No more context switching. No more copy-paste gymnastics. Just select text, right-click, and let your AI personas do their magic. It's like having a professional writing team built into your browser.
