Publishing Platforms

Connect and publish to:
  • X (Twitter)
  • LinkedIn
  • Instagram
  • Facebook
  • TikTok
  • YouTube
Click Manage Social Media Integrations to connect, disconnect, or refresh your accounts. You only need to do this once per account.

​
AI Captions for Posts (Optional)

Tell the AI how to write your social media post text. Examples:
  • “Make it witty and add relevant hashtags”
  • “Write for LinkedIn with a strong hook and CTA”
  • “Write for TikTok using casual language and emojis”
Leave empty for a neutral auto-generated caption.
Destination works best at the end of a workflow chain like: Clips → Reframe → Captions → Destination
