Press ⌘J in any app, sketch what you mean, and send a polished message that still sounds like you. Never generic, never off-tone.
Fragments are fine. CMD + J gathers the context around the thread, who's talking and what was just said, and uses it to turn three words into a finished message you'd actually send.
CMD + J accelerates founders, sales, customer succes, engineers and product manager
It learns from messages you've already sent, then matches your tone: warm, concise, lightly playful, whatever you actually are.
It gathers the context around your reply: who you're talking to, what was just said, which channel. It uses that so every draft fits the conversation, not a blank page.
Slack, Mail, Teams, any text field. One system-wide hotkey, the same result.
On-device option. Context is read in the moment and never stored.
Review and edit every draft before it sends. It never sends on its own.
Sketch the gist, hit enter, done. A finished draft before you'd finish typing.
Slack replies, emails, Teams pings, even a clean AI prompt. Pick the format and CMD + J shapes the draft to fit it.
