Writing with GrammarGem
App-aware switching
Let GrammarGem pick the right Mode for the app you’re in.
App-aware switching detects the app you’re writing in and applies the Mode that fits — Email in Mail, Punchy Post in X, Team Chat in Slack — so you don’t have to toggle anything.
Enable it in Settings → General. You can map any app’s bundle identifier to any Mode, including your custom ones.
Paid feature
App-aware switching is part of the lifetime license.
