Why turn a PDF into a podcast
You have 30 to 60 minutes a day that aren't usable for reading: commute, exercise, errands, meals. That's time you can reclaim with audio. A well-built podcast doesn't replace active learning, but it consolidates what you've learned actively and keeps you in the topic effortlessly.
The issue with raw text-to-speech is it's mechanical and tiring. A robotic voice reading a textbook for 30 minutes isn't enjoyable. Diane takes a different approach: the AI rewrites the PDF as a teaching podcast script, with transitions, mid-summaries and a natural tone. The result feels like an educational podcast you'd choose to listen to.
Several audio formats
Narrative monologue
A single voice presenting your material clearly, like a condensed lecture. Best for dense topics where you want the raw content.
Two-voice conversation
Two voices in dialogue: one explains, one asks the beginner's questions. The dynamic helps memory because you naturally want to answer the questions raised. Passive active recall.
Audio quiz
Diane turns your course into an audio quiz: the question is read, 5 seconds of silence for you to answer mentally, then the correct answer. Listen on the go and actually test recall.
Natural voice, several languages
Diane's voices are synthetic but with intonation, breath and inflection close to human speech. Pick male, female or neutral. The podcast is generated in the language of your source, with playback speed between 0.75x and 2x.
When to use it
The podcast isn't your first study step. It consolidates and maintains what you've already worked actively via flashcards or quizzes. Use it to turn a 30-minute commute into 30 minutes of quality passive review instead of music for the thousandth time.
Use cases
Students: course podcast on the train, chapter podcast the night before an exam, re-listening podcast when your eyes are tired. Pros: absorb an internal procedure during a work trip, listen to a report in the car. Self-learners: progress on a topic while doing daily tasks.
