What is Lightkey?

Lightkey is a typing assistant that works across any application on your computer, offering AI-powered text predictions and corrections as you type. It suggests single words and multi-word phrases based on context, catches spelling errors, and includes a spell-checker. The tool supports over 85 languages, making it useful for people who write in multiple languages or work internationally. Rather than replacing your keyboard, Lightkey sits on top of existing applications, so you can use it in email clients, messaging apps, document editors, browsers, and custom software without changing your workflow.
