MirrorCaption is a simultaneous interpreter in your pocket. It listens to a live conversation and gives you the other language as it is spoken — in meetings, lectures, calls, and face-to-face conversations. Point your iPhone at any conversation and watch the words appear on screen the moment they are said, in the original language and translated into yours. When you're done, get a clean AI summary of everything that was said. REAL-TIME CAPTIONS AND TRANSCRIPTION Live captions appear as people speak, with high accuracy. MirrorCaption works as a speech to text app for meetings, lectures, interviews, and videos — no file to upload, no recording to process afterwards. Real-time transcription starts the second you tap record. LIVE TRANSLATION, BOTH DIRECTIONS See real-time translation of what is being said, in your own language, as it happens. The face-to-face mode splits the screen across the table, so two people speaking different languages can hold a natural conversation — each reading their own side, each in their own language.
