Kalamy sits in your menu bar. Select text in any app — Gmail, Slack, VS Code, Notion — and press Cmd+C twice. A popup appears with the result. 7 AI writing actions: fix grammar, rephrase, shorten, formal, friendly, translate (14 languages — always free), and explain any text in plain language. Works in every app on Mac and Windows. Not a browser extension. $5/mo Pro. 14-day free trial. No signup required.
