About

Your big announcement gets buried in 47 unread messages. The quarterly win? Three thumbs-up emojis and silence. Important updates feel like shouting into a void. Instead, make messages impossible to scroll past. Claude creates custom GIFs that match your message, your brand, and your team's vibe—so your announcements actually land.

Stop sending text walls. Start sending moments that stick. Celebration GIFs That Feel Personal Launch party? Sales milestone? Team anniversary? Get animated celebrations with your team's inside jokes, not generic confetti from Giphy. Announcement Animations That Stop the Scroll Product updates, policy changes, deadline reminders—turn forgettable text into eye-catching visuals people actually notice in a busy channel. Custom Reactions for Your Culture Build a library of team-specific reaction GIFs. The running joke from last quarter's offsite. The CEO's favorite phrase. GIFs that make your Slack feel like your Slack.

  • · Turn forgettable announcements into messages people actually notice
  • · Create team culture artifacts—inside jokes that live in your emoji picker
  • · No design software or animation experience required
  • · Brand-matched animations that feel custom, not clip-art

Not for

  • · Complex character animations (walking people, detailed mascots) work best as simple, stylized graphics
  • · Very long text may need to be shortened for readability at Slack preview sizes
  • · Custom emoji uploads require Slack admin permissions for your workspace

Example prompts

Exploring styles before committing

Before we build the full GIF, show me 4 different animation styles for announcing our Series B funding. Give each a name and describe the vibe: one corporate, one playful, one minimal, one over-the-top celebration.

Celebrating a team milestone

Create a celebration GIF for our engineering team shipping v2.0 after 6 months of work. Include the text "WE SHIPPED IT" with animated confetti. Make it feel triumphant but not cheesy. Our brand color is #10B981.

Making a policy update noticeable

I need to announce new PTO policy changes in #general. Nobody reads these. Create an animated banner that says "New PTO Policy - Check Your Email" with a subtle pulse effect that catches attention without being annoying.

Building team reaction GIFs

Our team says "ship it" constantly. Create a reaction GIF with a cargo ship sailing across the screen and the text "SHIP IT" appearing dramatically. I want to upload this as a custom Slack emoji.

Deadline reminder that lands

Create an animated reminder for our Friday 5pm expense report deadline. It should feel urgent but not stressful. Include a ticking clock element and the text "Expense Reports Due Friday 5PM."
