Caplo
Caplo is an iPhone app companion that turns live audio from other apps into real-time translated captions in a floating Picture-in-Picture window.
Overview
Caplo is an iPhone app companion that turns live audio from other apps into real-time translated captions. It is designed for situations where subtitles are missing, delayed, or in the wrong language, and it displays the translation in a floating Picture-in-Picture window while you keep using the original app.
The product page positions Caplo for live streams, anime, sports commentary, podcasts, courses, news, and live events. It also supports session history, iCloud sync, and Markdown export, which makes it useful not only for watching live content but also for reviewing and saving transcripts afterward.
