Review a recorded lecture without replaying every minute.
Find the main concepts in a spoken class, seminar or course recording. Read an organized summary, then listen to a shorter version when you want to revisit the explanation.

A recording is a source. A useful summary helps you study it.
When several lectures are waiting, restarting each one can consume the time you meant to spend practising. MinuteMinds helps you review the argument and identify where the full explanation still matters.
Review concepts together
A structured summary keeps related ideas in context. Use it to orient your revision and identify the sections you need to study more carefully.
Use listening time for revision
Generate a short spoken summary in English or Spanish. Listen between study sessions, with the written result available when you need to check the wording.
Know when to return to the class
Concept coverage and quality signals are automated guidance. Worked examples, diagrams and mathematical notation may still require the original recording and your course materials.
How it works
Pick one recorded class
Upload an audio or video recording you have permission to process. A clear explanation is more useful than slides without narration.
Set your revision language
Choose English or Spanish and review the estimated balance usage. Confirm only when the source and output choices are correct.
Use the result as a starting point
Read the concepts, listen to the audio and make your own notes. Return to the original for evidence, solve the exercises and check anything used in assessed work.
One source. A result you can check.
This is a saved result from an original test talk about decision-making under limited attention. Play the source, compare the five ideas and listen to the generated summary. No account or upload is needed to explore it.

The five ideas in the summary
Attention limits make information costly
Attention is scarce; extra information has opportunity costs, so preserve decision-relevant evidence and show marginal cost.
Calibrate rigor to reversibility
Cheap-to-reverse choices need modest evidence; irreversible ones need more analysis. Miscalibration causes paralysis or careless damage.
Expected value guides uncertain comparisons
Expected value weights outcomes by probability, highlights assumptions, but never guarantees results or replaces judgment.
Base rates anchor case judgment
Start with outside-view base rates to avoid overconfidence, then update them with evidence explaining why this case differs.
Premortems surface actionable risks
Premortems ask how a plan could fail, make dissent easier, and should yield specific mechanisms, warning signals, and mitigations.
Read the listening script (English)
Better decisions do not always come from more information, because attention is limited and every extra source has an opportunity cost. A useful system preserves decision-relevant evidence and makes the cost of more attention visible. Calibrate the amount of analysis to how reversible the choice is: move quickly with modest evidence when a decision is easy to undo, but use more analysis, more independent evidence, and an explicit look at downside when it is hard or impossible to reverse. Expected value helps compare uncertain options by weighing outcomes against probabilities, but it is not a promise or a substitute for judgment. Start with base rates, then update them with evidence about why this case differs. Finally, use a premortem to identify specific failure mechanisms, early warning signals, and mitigations.
The source and generated voice are in English. This is one MP4-upload test, not three separate tests or a full university lecture.
The automatic assessment found all five detected concepts in this result. It is not an independent accuracy guarantee. The 79% reduction compares source speech with generated audio; the MP4 includes a brief silent tail. Other sources can produce different results.
Before you upload
Does it read slides, PDFs or handwritten equations?
This workflow uses spoken audio from an uploaded recording. It does not read PDFs, slide images or the board. If an equation or diagram is not explained aloud, consult the original material.
Does it replace attending or studying the lecture?
No. It is a revision aid, not a substitute for the course, practice or your teacher's instructions. Summaries can omit nuance or contain errors; check important points against the source.
Is the demo a full university lecture?
No. It is a short, original test talk about making decisions under limited attention. The saved result shows the workflow and its measurements without implying that the same result applies to a whole course.
Can I keep summaries from several classes?
Completed results remain in your account library for later reading and listening. This page does not promise automatic cross-course analysis, flashcards, quizzes or live classroom recording.
