AI for Slack on Mac

AI in your Slack composer — not in another tab.

Stop pasting Slack threads into ChatGPT. ElastoType reads the conversation you're already in and helps you reply, rewrite, translate, or summarize — right where you type, then replaces the text in place.

What it does inside Slack

💬

Reply in your tone

Draft a reply that fits the thread — it reads who said what and matches the register, casual or formal.

🪶

Soften or sharpen

Turn a blunt line polite, or a rambling one crisp, before you hit send.

🌍

Translate

Write to teammates across languages — translate your draft or their message in place.

📋

Summarize a thread

Select a long back-and-forth and get the gist or the action items in a couple of lines.

Your saved prompts

"Reply in my voice", "make it a standup update" — run the prompts you repeat, by name.

No context-paste

Because it sees the open thread, you skip the "here's the conversation…" setup every time.

It reads the room

The reason AI replies usually feel generic is that the model never sees what you see. You end up pasting the whole thread and explaining who's who.

ElastoType passes the on-screen context with your request — the message you selected, your half-written draft, and the visible conversation — so "how should I reply?" produces an answer grounded in the actual thread, not a guess. Ask it to reply and it already knows what's being discussed.

Questions

How do I use AI in Slack on a Mac?

Install ElastoType, then select text in any Slack message or your draft. A popup lets you reply, rewrite, translate, or summarize, and the result replaces your selection in the composer — no copy-paste to ChatGPT.

Does it understand the conversation?

Yes. It can read the thread and draft you're looking at, so a reply matches the tone and you don't have to paste the context yourself.

Can it translate Slack messages?

Yes — select a message or your draft and translate it into natural, tone-matched language.

Is it free, and is my Slack data private?

Free to start, no account. Your text only leaves your Mac to reach the AI model, never to us; on Lifetime it goes straight to your own provider key.

Reply faster, without leaving Slack.

Free, no account. Select a message and try it.
