Personal
Predictions come from your own writing: your words, your phrases, your style.
Private
Runs on your device and works offline. Your content is never sent to the cloud.
Everywhere
Natively in Teams, WhatsApp, Notes and virtually every desktop app, and across the web with our Chrome and Edge extensions.
Express yourself faster, everywhere
Lightkey is natively integrated with virtually every desktop and web app, from Teams, WhatsApp, Notes and Docs to emails and spreadsheets. That includes AI assistants like ChatGPT, Gemini and Copilot, and coding tools like VS Code and Cursor.
Every web app, including
Google Workspace
Lightkey's Chrome and Edge extensions bring the same predictions to virtually every web application. Write in Gmail, Google Docs, Sheets and Slides, WhatsApp Web, and the web tools your team uses every day.
Turbocharge your typing and gain more time
Lightkey predicts up to 18words ahead, including punctuation marks, in more than 80 languages. Accept a full sentence with a single Tab and keep going.
Communicate your personal tone & style
Every prediction comes from your own writing: the terms, phrases and expressions you actually use. What Lightkey suggests is what you would have written.
One personal prediction profile for your desktop and the web. A phrase you type in Teams can be predicted in Gmail and vice versa, while everything Lightkey learns stays locally on your device.
Private by design
Personal shouldn't mean public. Lightkey learns and predicts entirely on your device and works offline.
Your content is never sent to the cloud, in any application
