Lazur is an AI assistant for Slack on your Mac: hold ⌥ ⌘ while a thread is open and ask it to sum up, explain or draft the reply. Hold fn to dictate a message straight into the compose box.

## Quick answer

- Hold ⌥ ⌘ in Slack and ask about the thread on screen. Lazur answers out loud.
- Say “draft a reply, Thursday works” and the draft lands at your cursor for you to check.
- Hold fn to dictate a standup. It comes out as clean lines, not a transcript.
- Works in the Slack Mac app and Slack in the browser.

## What Lazur does in Slack

Slack is where questions pile up. Lazur sits in the notch above it. Hold ⌥ ⌘, say what you need, and it looks at the Slack window you have open. You do not copy the thread into a chat window first.

- **Catch up:** “what did I miss in this channel?”
- **Reply:** “draft a reply, yes to Thursday, ask about the budget”
- **Find your way:** “where's the setting for notifications?”
- **Type by voice:** hold fn and talk. The text appears in the compose box.

## Dictating Slack messages on a Mac

Click the compose box first. Hold fn, say the update the way you would say it in standup, and let go. Lazur types clean, formatted text at your cursor. Filler words drop out, and lists come out as lists.
