The problem · The fix

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

😩 What's draining your week

  • Engagement decides reach, but replying to 100 comments/day burns 90 minutes.
  • Generic 'thanks for sharing' replies kill your authority.
  • ChatGPT replies sound like a customer support bot.

⚡ What PostSpark gives you

  • Brand Voice AI keeps replies in your tone — Pro users see this auto-applied.
  • 5 reply angles per comment so you pick the one that fits.
  • Free for 3 replies/month, Pro at $19/mo unlimited.
