Transcape is a live captions translator for iPhone and iPad, built for foreign-language videos, meetings, podcasts, livestreams and courses. When you start a session, Transcape recognizes the current audio and shows the original speech plus translation as floating bilingual captions, so you can follow what is being said while you watch or listen. Why use Transcape: - Turn spoken audio into real-time captions - Translate video calls, meetings, podcasts, livestreams and courses - See original text and translation together as bilingual subtitles - Keep captions visible in a floating caption window while using other apps - Use Apple on-device speech recognition and translation resources - Audio, recognized text and translations are not uploaded to our servers - Start with a 30-minute free trial, then choose yearly or early-bird lifetime access Transcape is designed for active listening, not ordinary pasted-text translation. Some languages may require Apple speech or translation resources to be downloaded first. Protected media or unusual audio sessions may not provide usable app audio through the system broadcast path.
