PDF to audio for studying
Convert a study PDF into an audio lesson
Long PDFs are difficult to revisit when you are away from your desk. Upload the file, choose the level of detail and get a spoken explanation you can listen to during a walk, commute or break.
Upload your PDF
Use lecture notes, course reading or presentation slides up to the current file limits.
Set the lesson
Choose a summary type, language and duration that match the next review session.
Listen and review
Hear the key ideas, then check your recall with questions and flashcards.
What happens after you upload the PDF?
SintetizAI extracts the document content before preparing the lesson. If a page is scanned, OCR can be used where selectable text is not available. The result is organized as a spoken explanation rather than a page-by-page reading.
What can you do with the audio?
- Review the main ideas without opening the PDF again.
- Listen to the lesson in the language you choose.
- Use recall questions and flashcards after listening.
- Return to the original source when a detail matters.
Is PDF to audio a replacement for the original?
No. It is a layer for understanding and review. Important facts, formulas and instructions should always be checked against the original material.
