Hemmingway for Slack · Pilot

Better writing. Inside Slack.

Turn a rough draft into a message you want to send. Polish, Shorten, Make warmer, Make more professional, or give Hemmingway your own instruction.

Checking pilot availability…

A workspace owner may need to approve installation. A Hemmingway AI account is required. Existing account allowances apply; free usage is limited.

Your words. Your decision.

Type /hemmingway followed by a writing request to get a response only you can see. Use /hemmingway on its own to open the editor, choose Rewrite with Hemmingway from a message’s menu. Write from a brief or rewrite a draft, then review the private preview.

Edit and refine the result inside Slack. The Chrome extension adds recording inside the popup, with a waveform, pulsing indicator and timer. In Slack desktop, use your device’s dictation in the text fields.

With the Chrome extension, choose Insert into Slack to place the preview in your draft, then press Slack’s normal Send button. In the native app, connect your Slack account once and confirm Send message to send as yourself. Nothing is sent automatically.

USE YOUR HEMMINGWAY AI ACCOUNT

Add Hemmingway to your Slack workspace.
Run /hemmingway and choose Connect Hemmingway.
Sign in to Hemmingway, generate a connection code, and paste it into the Slack dialog.
Write a draft or brief and preview your result.

Hemmingway processes the text you explicitly submit. The native app does not read channel history or unsent composer drafts, and it does not send automatic replies. To rewrite directly in a supported Slack web composer, use the browser extension.

This pilot is distributed directly. It is not yet listed in the Slack Marketplace.
