The problem · The fix

What's costing you hours — and how PostSpark removes it.

😩 What's draining your week

  • 80% of viewers decide in the first line. Most posts die on the hook.
  • Writing 10 hook variants manually takes 20 minutes per post.
  • You have no way to predict which hook will actually perform.

⚡ What PostSpark gives you

  • 10 distinct hook types per request — variety guaranteed, not 10 reworded versions.
  • Predicted scroll-stop score per hook, trained on top-performing X & LinkedIn posts.
  • Free for 3 uses, Pro at $19/mo. Pair with PostSpark to build the full post.
