What makes a useful study summary?
A study summary should preserve the ideas that help you understand the subject. That includes definitions, relationships, examples and conditions that change the meaning of a claim. Shortening every paragraph is less useful than giving the material a clear structure.
Use the summary as a study session
- Listen once to build a map of the topic.
- Pause and answer a recall question before checking the answer.
- Return to the flashcards when you need a shorter review.
- Use the original material to verify important details.
Supported study material
You can work with PDF, Word, PowerPoint, Excel, OpenDocument, Markdown, plain text, images with OCR and document URLs. The finished audio can be generated in Spanish, English, French, Italian or Portuguese.
