Key Features

AI-Powered Caption Styles

Our tool generates captions across four proven formats that perform best on TikTok:

  • Hook Captions: Attention-grabbing openers that stop the scroll and make viewers want to watch
  • Storytelling Captions: Narrative-driven text that builds curiosity and emotional connection
  • Trending Captions: Captions that leverage TikTok trends, sounds, and cultural moments
  • CTA-Driven Captions: Call-to-action focused text that drives likes, comments, follows, and shares

TikTok Character Limits

TikTok captions allow up to 2,200 characters. Our generated captions are optimized for engagement, not just length — short, punchy captions often outperform long ones.

Tips for Great TikTok Captions

  • Use the first line as your hook — it shows before "See more"
  • Add relevant hashtags after the main caption text
  • Include a clear call-to-action ("Comment your answer below!")
  • Use line breaks to improve readability
  • Mirror the energy of your video in your caption tone
