What is Caplo?

Caplo is an innovative iOS application designed to provide real-time captions and translations for any audio playing on a mobile device. Developed by Sparklight AI, it solves the problem of inaccessible or untranslated content by capturing system audio and displaying text via a Picture-in-Picture floating overlay. The tool supports 12 major languages, including English, Chinese, and Japanese, making it ideal for consuming foreign media or attending international meetings. Users can follow along with live sports, anime, podcasts, and video calls without needing native subtitle support from the source app. Its core capabilities include instant transcription, cross-app compatibility, and iCloud synchronization for saving session history. Caplo fits perfectly into the workflows of language learners, international business professionals, and media enthusiasts who need immediate textual context for audio content.
