Pros & Cons

Captions AI

Strengths

  • +Eye contact correction actually works on good footage — it's the feature that makes talking-head videos shot on a phone look polished
  • +Translation with voice cloning is useful for reaching non-English audiences without hiring a voiceover artist
  • +The mobile app is fast enough to go from recording to posted in under 5 minutes for simple content

Limitations

  • -Watermark on free exports is aggressive — you can't share anything to evaluate it socially before paying
  • -Eye contact correction degrades noticeably on lower-quality video or when you move your head a lot
  • -Background removal is usable outdoors or in good light but struggles in typical home office lighting
