rozeta: AI Lecture Notes

rozeta is an AI lecture notes app for college students.
Write while you record, and rozeta creates transcripts, explanations, translations and quizzes.

■ Handwriting and recording, linked page by page
Import your lecture slides as a PDF file and write on each page while you record.
When the slide changes, tap the Mark button. The recording so far is linked to that page, and your note moves to the next page. When you review, tap a page to hear the explanation from that point.

■ Speech recognition that gets technical terms right
Lectures that mix Korean and English are transcribed exactly as your professor said them.
- Terms spoken in Korean are written in Korean with the English in parentheses, and terms spoken in English stay in English.
- Formulas, symbols and units use standard notation.
- Add technical terms or proper nouns under Vocabulary, and they're transcribed just as you wrote them.

■ AI explanations built on what your professor said
Explanations don't rely on the slides alone. They're based on what your professor explained and emphasized in class, and they take the handwriting on each page into account.
You can also create an overview that puts a whole lecture into one document.

■ AI quizzes made from your class
Questions come from what was covered in class. Take a quiz before the exam, and replay the part of the lecture behind any question you missed.
A cumulative quiz combines several lectures so you can check everything on the exam at once.

■ Lectures in another language, translated
Whatever language the class is in, transcripts can be translated.
Translations and AI explanations are available in Korean, English, Japanese, Chinese, Spanish, French and German.

■ Premium handwriting
Your S Pen's pressure comes through with no lag. You get pens, highlighters, shapes, the lasso and text, plus 8 paper types.

■ Pick up on any device
Notes and recordings are saved to the cloud. Open them on iPad, Galaxy Tab, your phone or the web, and playback picks up where you left off.

Made for students who
- record lectures but rarely listen back
- want handwriting, lecture recordings and review in one place
- want accurate transcripts of lectures full of technical terms
- want to review lectures given in another language in their own
- want AI study help that reflects what their professor said
