Caplo brings live AI captions to iOS

Caplo is a real-time transcription and translation tool for iOS that uses system-wide audio capture to display live subtitles in a floating Picture-in-Picture window. It enables instant captioning for any mobile application—including YouTube, Zoom, and Netflix—supporting over 12 languages to break down communication barriers during meetings, livestreams, and media consumption.

// ANALYSIS

Caplo elegantly bypasses iOS sandboxing constraints to provide a system-wide utility that feels like a native OS feature.

  • Leverages ReplayKit for low-latency system audio capture without requiring manual video uploads
  • Floating PiP overlay maintains caption visibility across all apps for a seamless multitasking experience
  • Fills a critical gap in mobile accessibility for foreign-language content and real-time transcription
  • Practical $3.99/mo pricing or pay-as-you-go credits offer flexibility for casual and power users alike
  • Strong focus on privacy with local session history and optional iCloud synchronization
