## What is rozeta?

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 Apple Pencil'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, iPhone 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

### 5/5 — 레알 좋네

*2026-10-02*

클로바노트의 말도 안되는 스크립트 보다가 이거 쓰고 광명 찾음 진짜 어떻게 한 거지? 무료는 아니지만 공짜로 클로바노트 따위 쓸 바엔 돈 내고 이거 쓴다 개발자님 감사합니다

### 4/5 — 마음에 드는데...

*2026-09-16*

음성 인식도가 높고, 슬라이드와 음성파일을 동기화할 수 있으니 편리하더라고요. 기존 노트 앱에서 갈아타려고 요 며칠 사용해봤는데, 아쉬운 점이나 오류 사항이 있어서 건의 드립니다.
1. 음성 녹음하며 파일 1의 슬라이드를 사용하다가, 다른 자료 파일을 열어 필기에 함께 사용하려고 하면 앱이 튕겨요. 음성 녹음 자체가 날아가서, 복구되지 않은 적도 더러 있었고요. 이건 부디 하루빨리 고쳐졌으면 좋겠습니다.
2. 필기 내용에 올가미 툴을 사용했을 때 크기 조정은 가능하나, 회전 기능이나 글씨의 색 변경 기능은 지원하지 않아서 불편해요. 두 기능도 도입해주세요! 3. 키보드와의 연동성이 떨어져서 불편해요. 타 필기 앱의 경우 키보드의 좌우화살표로 슬라이드를 넘길 수 있는데 지원이 안 되네요. ctrl +Z도 안 될 때가 가끔 있어요. 튜토리얼엔 스페이스바로 깃발 기능이 가능하다고 적혀있었는데, 제가 테스트해봤을 땐 아예 안 됐어요. 4. 개요나 북마크 추가 기능이 추가되었으면 좋겠어요. 5. 홈화면에서 새 노트를 추가할 땐 PDF 파일 불러오기가 안 되더라고요. PDF 불러오기도 지원되었으면 좋겠습니다. 6. 현재는 앱에서 녹음하는 것만 가능한 것 같은데, 따로 녹음 후 녹음 파일을 올릴 수도 있게 해주셨으면 좋겠습니다.

### 5/5 — 너무 좋네요

*2026-09-06*

지난주에 직접 사용해봤는데 정말 괜찮았어요!

교수님 강의자료랑 음성파일이 거의 완벽하게 연결돼서 강의를 다시 들으면서 해당 슬라이드를 바로 확인할 수 있어서 복습할 때 특히 편했습니다. 그냥 녹음파일만 듣는 것보다 훨씬 이해가 잘 되는 느낌이에요.

그리고 필기한 내용도 첨삭이나 수정이 가능해서 강의 들으면서 정리하기에도 좋았습니다. 시험기간에 복습할 때 꽤 유용하게 쓸 것 같아요. 👍

### 5/5 — 좋아요 근데 보완해야할점 있습니다

*2026-08-31*

저는 갤탭으로 필기를 해서
S펜 지우개 버튼을 많이 쓰는데 안된다는점이 매우 불편하고 다른 노트어플은 제스처ex. 손가락 두번 톡톡으로 이전(컨트롤 z느낌) 기능이 없는게 아쉽습니다

이 외에는 진짜 혁명입니다…
획 쓰는데 레이턴시도 삼성노트급으로 없다고 봐도 될정돕니다

이런 어플 만들어주셔서 정말 감사합니다

### 5/5 — 개쩔음

*2026-07-09*

이거깔고 클로바노트니 뭐니 다지움

### 5/5 — 굿

*2026-05-11*

리뷰 별로 없어서 그냥 궁금해서 깔아봤는데 타 강의녹음어플 기능은 기본으로 탑재+AI 분석, 요약 이라서 지피티 없이 공부하기도 좋아요 대박입니다

### 5/5 — 정확도 미쳤어요

*2026-04-11*

다 알아듣고 적어줍니다 

대학생들에게 최고의 앱이에요

### 5/5 — 진짜 좋음 얼마나 좋냐면 진짜로 좋음

*2026-04-08*

대학 전공수업 들을 때 다른 앱들도 많이 사용해봤는데 이건 진짜 좋네요.. 경제학과라서 수식도 많이 필요한데 전부 문제없고, 영어로 경제 설명하시는 교수님 말씀도 전부 쉽게 공부할 수 있게 도와줍니다! 1학년 때 부터 이 앱과 함께 공부했다면 과탑했을만큼 유능한 앱입니다!!!

### 5/5 — 음성 잘 인식하는 AI 녹음 어플

*2026-04-06*

다른 녹음 어플들 사용해봤었는데 이것만큼 잘 인식해서 적어주는 어플 못 봐서 계속 사용하고 있어요. 교수님이 수업시간에 영어랑 한국어랑 섞어서 수업하셔도 잘 인식하고, 전공 단어들도 미리 입력해서 인식하기 쉽게 만들어서 좋아요. 컴퓨터랑 앱 둘 다 사용하는데,앱으로 녹음한 자료들 쉽게 볼 수 있어서 유용하게 사용하고 있어요. 특히 슬라이드 마다 중요한 내용들 정리해주고 교수님이 강조한 부분들도 잘 캐치해서 알려주니까 시험기간에 효율적으로 공부 가능해서 잘 쓰고있어요.

### 5/5 — 말도 안 되는 정확도네요

*2026-04-06*

오래된 노트북으로 사용해서 생각보다 잡음이 많이 들어가고 음성이 깔끔하게 녹음되지 않더라구요. 그런데도 교수님의 목소리만 정확하게 인식해서 텍스트로 변환하는 거 보고 정말 놀랐습니다.. 인식률 하나는 모든 앱들 중에 최고 같습니다 👍 양천구불주먹의오른팔 믿고 한번 써보세요

• On tablets, a preview opens next to the recording list.
• Undo in segment editing, renaming and reordering courses, and more.
• More reliable sync and bug fixes.

### 2.4.0 — 2026-09-29

• Added handwriting directly on the recording screen. The slide for the segment you are listening to opens as you go.
• Added note attachment for recordings made without one.
• Redesigned the player bar. Segments appear as blocks, and dragging previews a thumbnail of that segment.
• Added 1.75x playback speed, and the app now remembers your last choice.
• Added a Save button to segment editing.
• Added English UI support, selectable from the language menu in Settings.
• Fixed handwriting loss when the same page was edited on multiple devices.
• Redesigned the subscription screen and added standalone AI credit purchases.
• Fixed Korean text not displaying in some PDFs, incorrect duration for imported recordings, and various other bugs.

### 2.3.0 — 2026-09-23

• Notes are much faster and smoother throughout. Page grids, note lists, and the transcript list in a recording were rebuilt from the way they draw up.
• Jumping to the current segment is instant, even in long transcripts. Nothing to wait for with thousands of sentences.
• Flipping pages left and right no longer makes you wait. The next page is there immediately, and you can keep writing mid-flip.
• Keep several notes open and switch between them from the tab strip in the app bar. Tap the count to see every open note, or close one without opening it.
• A Recent Notes shelf was added to the home screen. Notes you were just in,
  across subjects, line up as covers you can swipe through.
• Sort a subject's note list — four orders, including most recent and title.
• Sidebar navigation on tablets was tidied up. Tapping an item moves you sideways to that destination instead of stacking up back steps.
• Bring a PDF in from another app as a note.
• When something goes wrong, the error details now reach us automatically so it can be fixed sooner.
• Tightened up edge spacing that was off in places on tablets.
• Fixed text boxes not finding their place when you turned the page, along
  with various other bugs.

### 2.2.0 — 2026-09-17

• AI quizzes were rebuilt. Make several sets from one lecture, add questions
  to a set, or regenerate it — and pick which segments a set draws from.
• Every question now shows where it came from. Tap the chip with the note,
  page, and timestamp to hear that moment again, and questions you skip with
  "I don't know" come back for review later.
• Each subject has an AI Quiz hub. Retry just the questions you got wrong, or
  build a comprehensive quiz spanning several lectures.
• Short-answer marking is more forgiving. Spacing and spelling variants count
  as correct, and borderline answers get a second look from AI.
• A timetable was added. Enter class times, rooms, and instructors per subject
  to see your week at a glance, get a "class now" row on the home screen, and
  be reminded before class starts.
• Notes can scroll continuously up and down. Choose page-flipping or scrolling
  in Settings.
• Notes open much faster. They now open from your local copy first and verify
  afterwards, with page images and thumbnails kept on hand.
• Squeeze or double-tap Apple Pencil Pro to fan the tool palette out at the
  pen tip. You can change what each gesture does in Settings.
• Lasso copy and paste now use the system clipboard, so you can paste a
  selection into another app and bring images or text from other apps into a
  note. Long-press an empty spot with the lasso to get a Paste button.
• Share a PDF from another app to open it straight into a new note — or into
  your recording if one is running.
• AI explanations now include a lecture overview, mark anything not on the
  slides, and take your own handwriting into account.
• Fixed transcription failing when you started it before the audio finished
  uploading.
• Fixed handwriting being covered by another page's ink, along with various
  other bugs.
