InboxIQ is a Gmail assistant designed to improve your email productivity while ensuring your privacy. It summarizes lengthy email threads into concise points, making it easier to grasp the main ideas quickly. Additionally, it can assist with follow-up questions based on email content, providing AI-powered responses. Users must provide their own OpenAI API key, which ensures that their data is handled securely and privately. The processing of emails is done locally on the user's device, and no data is stored or seen by third parties. This approach offers customization options and enhances productivity, all while prioritizing user privacy.
