BetterSend vs Rewrait
Rewrait vs BetterSend for Slack and work messages
Both have a desktop app. Pick BetterSend if you write mostly in Slack or Teams: it adds a button to the composer, in Chrome and in the native apps on Mac and Windows, translates and explains the messages you receive, accepts drafts in any language and costs less. Pick Rewrait if you want one shortcut that rewrites selected text in any app, including on Linux.
