Predictive text in Microsoft Teams: how Lightkey works in chats and channels
Yes, Lightkey works in Microsoft Teams. As you type a chat message, a channel post or a reply, Lightkey predicts your next words in grey right where you're typing. Press Tab to accept, or keep typing. It also suggests spelling corrections as you go.
How it works
Install the Lightkey desktop app and open Teams. Predictions appear in the message box of chats, channels and meeting chats, with nothing to configure in Teams.
Lightkey works in the Teams desktop app on Windows. In Teams on the web, use the Lightkey extension for Chrome or Edge; it works together with the desktop app.
What it helps you write in Microsoft Teams
Teams messages are short, frequent and often repetitive. Lightkey learns the phrases you use most, such as:
“Sounds good, thanks.”
“Can we move this to tomorrow morning?”
“I've shared the file in the channel.”
“Joining in two minutes.”
Over a day of chat, accepting these with one key adds up to a lot less typing.
Private by design
Lightkey's prediction engine runs on your own computer. What you type isn't sent to a cloud service to get a prediction, and Lightkey keeps working offline. Your team's conversations stay on your device.
