Overview
Iris
Iris is a dedicated eye protection solution that helps you reduce the physical toll of long hours in front of a computer. By automatically adjusting your screen's color temperature and brightness, it eliminates the flicker and blue light that typically cause eye fatigue and disrupt your natural sleep cycles. You can choose from various pre-set modes like Health, Sleep, or Reading to match your current activity and environment.
The software works at the driver level to control the pulse-width modulation (PWM) of your monitor, ensuring a flicker-free experience even at lower brightness levels. Whether you are a programmer, designer, or office worker, you can customize every aspect of your display to protect your vision and maintain high productivity throughout the day without the typical afternoon burnout.
Lightkey
Lightkey is an AI-powered writing assistant that predicts your next words and phrases as you type in real-time. Unlike standard autocorrect, it learns your unique professional vocabulary and writing style to offer highly relevant suggestions across Microsoft Office, Outlook, and popular web browsers. You can significantly increase your typing speed and reduce keystrokes by simply hitting the Tab key to accept predictions.
The software operates locally on your machine to ensure your data remains private and secure while you work. It also includes a built-in dashboard where you can track your productivity gains, such as time saved and keystrokes avoided. Whether you are drafting complex legal documents, academic papers, or daily emails, Lightkey helps you maintain your creative flow without the distraction of manual typing errors.
