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.
Speechify
Speechify helps you turn any written text into high-quality audio so you can listen while you commute, exercise, or multi-task. Whether you are dealing with a long PDF for work, a physical book you need to scan, or a web article, you can instantly transform it into a spoken track. It uses advanced AI to provide human-like voices that make listening feel natural rather than robotic.
You can adjust reading speeds up to 4.5x to power through content faster or slow it down to aid comprehension. The platform is designed for students, professionals with heavy reading loads, and individuals with dyslexia or visual impairments. By syncing across your phone and computer, you can start a document at your desk and finish it on your walk using the mobile app.
