Turn live lectures into verifiable bilingual notes, summaries, and quizzes
Memo Card converts classroom speech to text while the lecturer is still talking and displays translated text next to the original, so students can follow fast delivery, unfamiliar accents, and technical vocabulary in real time.
Original speech and translated meaning are preserved together, and every note or AI answer can be traced back to a precise timestamp in the recording for verification before exams.
A linear transcript becomes timestamped branches, keywords, section summaries, course quizzes, and visual recaps, giving a structured entry point without hiding the complete transcript.
Search any term inside a session, open the matching moment, replay the audio at your preferred speed, and export material for revision, group work, or a personal archive.
