Features

Read full description

AstraLect turns lecture recordings into a timestamped transcript and structured study notes. Record or import audio or video, then review the original recording alongside the result. Keep the source close when you need to check a definition, formula, or example. AstraLect helps you: • Capture a class with the built-in recorder. • Import a file from your device. • Read a transcript with timestamps. • Review organized study notes in one place. • Jump from a note to the matching audio moment. • Move between Notes and Transcript without losing playback. • Retry processing without losing the recording. Your original audio remains available for playback so you can verify important details against the source. AI-generated content is a study aid and should be checked against your course materials. Please follow your school's recording policy and get permission where required.
