LectMate

LectMate is a web-based workspace designed for students and professionals who need to understand and review spoken content, particularly in a multilingual context. It takes live or recorded audio—from lectures, Zoom calls, or meetings—and turns it into a structured, searchable text document. The core function is to provide real-time transcription alongside simultaneous translation, creating a side-by-side bilingual record of the conversation.

The tool works by using a stack of AI models for different tasks. It employs models like 'gpt-realtime-whisper' for low-latency live transcription and 'gpt-realtime-translate' for streaming translation. After a session, stronger language models clean up the text, extract key concepts, and generate summaries. What makes it stand out is the integration of these features into a single workflow, combining real-time captioning, translation, keyword extraction, and audio replay in one place.

This tool is most beneficial for students studying abroad who attend lectures in a non-native language, as well as tutors and education teams who need to review sessions. Real-world use cases include following a fast-paced economics seminar in English with Chinese translations, preparing for exams by searching for specific terms in a semester's worth of lectures, or reviewing the key points from a complex customer service call without listening to the entire recording again.
