1. Generate Your Slack Chat Animation
Use the embedded Slack fake chat generator on this page to create your custom conversation. Set workspace and channel headers, add messages (with avatars, names, timestamps, threads, emoji reactions), and pick light or dark theme. This tool is designed for entertainment, skits, memes, and mockups - never for impersonation or deception.
- No app or signup required - everything runs in your browser.
- Preview your chat as you build it to match the classic Slack look.
2. Export for Overlay Use
Once your conversation is ready, export it as an animated video (MP4 or WebM). The animation includes Slack’s signature background, message flow, and reactions. Alternatively, export a static PNG screenshot for a cut-out overlay style.
- Animated video: Ideal for dynamic overlays in streams and edited videos.
- Screenshot: Perfect for quick, static overlays or cut-out effects.
3. Add the Overlay to Your Video or Stream
Import the exported MP4/WebM into your editing or streaming software:
- OBS: Add as a Media Source, position and scale it as a picture-in-picture inset.
- CapCut/Premiere/DaVinci Resolve: Place the video on a new track, resize, move to a corner, and round corners or add a phone frame for style.
Time the appearance of messages to sync with your voice-over or reactions for maximum impact.
4. Tips for Realistic & Ethical Use
- Label overlays as staged or for entertainment if they could be mistaken for real conversations.
- Use overlays for office skits, 'reply-all' chaos, or remote-work humor.
- For a masked/cut-out look, use the PNG export and mask it in your editor.
