Predictive text in Mattermost: how Lightkey works in channels and threads
Yes, Lightkey works in Mattermost. As you type in a channel, a thread or a direct message, 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 the Mattermost desktop app on Windows. Predictions appear in the message box, with nothing to install on your Mattermost server.
Using Telegram Web? Add the Lightkey extension for Chrome or Edge; it works together with the desktop app.
What it helps you write in Mattermost
Team chat repeats from day to day. Lightkey learns the messages you write most, for example:
“Deployed to staging, please test.”
“Can someone review my merge request?”
“Moving this to the incident channel.”
“Back in 15 minutes.”
For teams that run Mattermost on their own servers, Lightkey adds predictive text without adding a plugin or an integration.
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. That fits teams that self-host Mattermost to keep their conversations in-house.
