A private study companion for class audio
Ezra helps you keep a class recording or imported course audio and video as one source in your private library. Read the transcript, return to a concise summary and key ideas, ask questions grounded in that class, and create study guides, quizzes, or flashcards when you are ready to review.
From classroom audio to active review
Record the class in the Ezra mobile app, or import a supported audio or video file you already have. The recording becomes one clearly bounded source, so the lesson you are reviewing does not get mixed with another class or with unrelated material in your library.
Open the source to read its transcript and concise summary, then scan the key ideas and useful takeaways. These views give you a faster way back into a long lecture while preserving the source itself for moments when wording, context, or emphasis matters.
Ask about the selected course source when a concept, example, or connection needs clarification. Ezra answers from that source rather than acting as an unrestricted general-knowledge assistant. A cited moment helps you return to the part of the class behind the answer and check it in context.
When you decide it would help, ask Ezra to create a study guide, quiz, or set of flashcards from the source. Nothing is generated automatically. You choose the tool and the moment, then use it to practise recall and identify which parts of the lesson deserve another look.
Start with what was actually taught
A lecture can contain definitions, demonstrations, cautions, examples, and questions in quick succession. Ezra gives the recording a readable form, so you can begin with the transcript and summary instead of guessing where an important point appeared. The transcript is useful when exact wording matters; the summary and key ideas are useful when you need the shape of the lesson first. Because each class remains its own source, the notes reflect that recording rather than quietly blending material from a different course.
Active study, when you request it
Rereading notes can refresh recognition, but a useful review session often needs a more active step. Ezra lets you request a study tool after the course source is ready. A guide can organize the major ideas and relationships. A quiz can help you practise retrieving information without looking at the answer first. Flashcards can turn terms, distinctions, and concise concepts into short rounds of recall. These tools are based on the selected class source and support your own learning; they do not complete an assignment, write a submission, or replace the judgment expected from you as a student.
One class, one conversation
Open a class source before you ask. Ezra uses that source as the boundary for the conversation and points back to the relevant moment, which makes the answer easier to verify. If the recording never covered a topic, the conversation is not meant to invent a general answer from elsewhere.
Questions students ask
Yes. Ezra can record class audio in the mobile app, or you can import supported course audio or video from your device. The recording becomes one source in your private library, where its transcript, notes, questions, and study tools stay together.
Ezra can transcribe the selected recording and present a summary, key ideas, and useful takeaways that help you review what was covered. Keep the original source available when accuracy is important, and compare any study note with the instructor's materials rather than treating generated text as an official course record.
No. Conversation is scoped to the class source you opened. Ezra is useful for asking what the lecturer said, how two ideas in that source relate, or where an example appeared. It is not an unrestricted subject tutor, a search of the whole internet, or a conversation across every course in your library.
No. Ezra supports review of a source you provide. You can explicitly create a study guide, quiz, or flashcards to practise, but the product is not positioned as completing graded work, writing submissions, or replacing your own analysis and your instructor's requirements.
Ezra is built for one person's private library across their devices. It is not a class portal, instructor dashboard, team account, or public notes feed. Your recording, transcript, questions, and study tools stay connected to the selected class source instead of becoming a shared course workspace.
