TwinMind is a personal AI sidebar that understands meeting and website content, providing you with real-time answers and drafting any content based on context. It allows you to access the latest AI models and ask questions about browser tabs, PDFs, YouTube videos, etc. TwinMind offers next-step recommendations during meetings and interviews, searches the web on the sidebar for instant answers, and emphasizes privacy by processing audio data directly on your device without storing it anywhere, ensuring audio cannot be replayed or accessed later.
