Overview
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.
Stretchly
Stretchly is a cross-platform break reminder tool designed to help you maintain your physical well-being while working at a computer. By default, it follows a rhythm of suggesting 15-second microbreaks every 10 minutes and longer 5-minute breaks every 30 minutes. These prompts encourage you to look away from the screen, stretch, or step away from your desk to reduce eye strain and physical fatigue.
You can fully customize the duration and frequency of these breaks to match your specific workflow or medical recommendations. The app lives in your system tray and provides unobtrusive notifications or full-screen takeovers depending on your preference. It is an ideal solution for developers, writers, and office professionals who spend long hours at a desk and need a simple, automated way to prioritize their health.
