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.

Notion

Notion provides you with a flexible, all-in-one workspace where you can build the exact tools your team needs.

The platform adapts to your specific way of working through its unique building-block approach. You can start with a simple page and transform it into a robust database, a Kanban board, or a collaborative calendar. Whether you are a freelancer organizing your personal life or a large enterprise managing global operations, Notion scales to fit your requirements while reducing tool sprawl and subscription costs.
