Why Teams Need Canned Responses in Slack

Slack moves fast. Customer success teams, HR, IT support, and managers all send the same messages repeatedly — status updates, greetings, standup templates, onboarding instructions, escalation responses. Typing them fresh every time is slow and inconsistent.

Lightning Assist lets you create shortcuts for your most-used messages and expand them instantly anywhere in Slack — and in every other tool you use throughout the day.

Works in Desktop & Browser Slack

Whether you use the Slack desktop app or Slack in Chrome, Lightning Assist expands your snippets identically.

AI Message Improvement

Select any message text in Slack, press the AI hotkey, and instantly rewrite it, adjust tone, or make it more concise.

Cross-App Consistency

Use the same snippets in Slack, email, Zendesk, Notion, and anywhere else. One library, every app.

Team Sharing

Share your Slack message templates with your entire team so everyone sends consistent, on-brand messages.

Common Slack Messages to Automate

Status updates — "Working on X, back by Y" templates
