How to Write Viral Captions

Even with AI, understanding the psychology of a great caption helps. Here is the formula we use:

  • The Hook (Line 1): This must be visible *before* the "more" button. Make a bold statement, ask a weird question, or call out a specific audience.
  • The Value (Body): Deliver on the promise of the hook. Educate, entertain, or inspire. Use line breaks to make it readable.
  • The CTA (End): Tell them exactly what to do. "Save this for later," "Share with a friend," or "Check the link in bio."
