Frequently asked questions

Is this audio to flashcards really free?

Yes. Duetoday gives free daily usage so students can try the workflow without creating friction. The exact free limit depends on the tool type, and heavier source-based tools have tighter daily limits than lightweight calculators or planners.

What works best as input for this tool?

The best input is specific, relevant, and already close to what you are studying. Clear notes, focused topics, structured prompts, and source material with enough detail almost always lead to better outputs than vague one-line requests.

Do I need an account to use it?

For basic free usage, usually not. If you want more runs, saved history, or to continue the result inside Galileo with flashcards, quizzes, summaries, or follow-up study, you should create a free Duetoday account.

What happens after I use this tool?

The best next step is usually to keep the same material moving. If you generate notes, turn them into flashcards or a quiz. If you generate a summary, turn it into a study guide. If you start with a source like audio, PDF, or YouTube, open it in Duetoday and continue the full study workflow there.

Strong next step

Use the free tool, then keep studying inside Duetoday.

Duetoday does more than generate a one-off output. It lets you keep going with the same material by turning lectures, PDFs, notes, and summaries into flashcards, quizzes, study guides, and guided AI follow-up study in Galileo.
