CaptionAddr adds bold, word-by-word captions to your videos on iPhone and iPad. Speech is transcribed on the device with Whisper, so your clip is never uploaded. Fix any word, pick from 20 fonts and export a new video with the captions burned in, ready for TikTok, Reels or Shorts. Free for clips up to 2 minutes with no watermark; Pro (monthly or yearly, with a free trial) goes up to 30 minutes. English speech only.
