## What is rozeta?

Lectures you recorded but never listened to again — now make the most of them with rozeta.
rozeta is an AI-powered study note that supports the entire learning process for university students, from recording lectures to reviewing them.

1. Slide-Synced Recording
Upload your lecture slides as a PDF and follow along during class.
Slides and audio are synced together, so when reviewing, simply select any slide to instantly play the lecture from that point.
No more scrubbing through long recordings to find what you need.

2. High-Quality Lecture Subtitles
Conventional STT services can't accurately transcribe university lectures filled with technical terminology.
rozeta uses high-performance speech recognition combined with AI correction to flawlessly convert even difficult terminology into text.
  - Subtitles: Displayed in real time during playback, so you can review comfortably without relying on audio alone
  - Scripts: Full lecture transcripts organized by slide

3. AI Study Content
Unlike generic AI explanations based solely on slides, Rozeta incorporates your lecture slides, the professor's spoken content, and your own notes to generate explanations that capture your professor's perspective and key points.

4. Lecture Translation
Don't give up on lectures in English. Rozeta provides accurately translated subtitles and scripts powered by AI.
With context-aware AI translation, experience a level of quality that sets it apart.
All study content can also be generated in your preferred language.

Recommended for
  - Students who record lectures but never get around to listening again
  - Students who need a more efficient way to review major coursework
  - Students struggling to understand lectures in English
  - Students who study with AI but wish it reflected their professor's actual lectures

### 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

### 5/5 — 요근래 가장 완벽한 음성 인식

*2026-04-02*

다른 어플에 비해 전문 용어 인식률이 월등히 높네요! 특히 다른 어 플에선 전공  수업에서 용어들을 영어로 설명하는지라 인식이 잘 되지 않았는데, 정확하게 인식되는거 보고 놀랐네요. 앞으로 여기 정착할듯..!

### 5/5 — 곧 떡상할앱

*2026-04-01*

클로바노트같은 음성인식앱은 일상대화는 몰라도 학문적인 내용 들어가면 인식 너므 이상했었는디 얘는 진짜 소름돋게 정확해요!!! 엄청 유용하게 쓰고있습니다

## Version history (last 5 releases)

### 2.1.0 — 2026-08-24

• Draw shapes — drag out a line, arrow, rectangle, ellipse, or triangle. Pause mid-stroke and what you just drew snaps into a clean shape.
• Export notes as PDF or images. Pick this page, every page, or just the ones you choose, and toggle handwriting, text, and images on or off.
• Crop inserted images. The original is left untouched, so you can undo it at any time.
• Pick the image tool and your recent photos appear right above the toolbar. Photos land in the middle of what you're looking at.
• Text editing was rebuilt — formatting now applies while you type in Korean, the caret stays inside the box when a line wraps, and you can set font size and line spacing.
• Wider pen thickness range, and the top half of the monoline slider now works.
• Notes open on the page you were last reading.
• Recordings pick up where you stopped listening, even if that was on another device.
• New logo, and a new app icon to match.
• Upgrading a plan now credits the time you haven't used and starts a fresh billing month that day. Upgrading from a gifted plan only charges the difference until the gift expires.
• Terms, privacy policy, and business information are now in Settings > About.
• Fixed accounts with payment history failing to delete.
• Fixed files sticking around after deleting notes or recordings, which made storage look larger than it was.
• Fixed the screen rotating to portrait when opening ink tool options in landscape, along with various other bugs.

### 2.0.1 — 2026-08-12

• Start recording from anywhere — tap Record on the home screen, pick a subject, and you're recording.
• Long-press notes and recordings to select several at once, then move them to another subject or delete them together.
• Reset your password and resend the verification email right in the app.
• Top up AI credits without changing your plan.
• Recordings made without lecture slides now open straight into the transcript and AI analysis.
• Dark mode reworked — cards and floating elements now sit at the right
  brightness, so lists and the top bar no longer glare, and the launch screen is dark too.
• Lists load much faster.
• "Current segment" now always jumps where it should, and the transcript follows playback smoothly.
• Sheets and dialogs were rebuilt so they open and move around the keyboard without stutter.
• Handwriting in a recording now looks exactly as it does in your notes — fountain-pen nibs, pressure-based thickness, colored-pencil grain, and highlighter overlap all match.
• Fixed handwriting disappearing or breaking up when you moved between devices. Most strokes that were already damaged come back on their own.
• Stroke thickness now follows measured pressure values, so strokes no longer come out too thin or too thick.
• Edits made on another device now come through. A note you've already opened keeps picking up handwriting, pages, and title changes.
• Fixed notes staying blank on a device when the lecture slides failed to download.
• Improved social sign-in — you may need to sign in again after updating.
• Fixed display issues with your name, subscription, and storage usage, along with various other bugs.

### 2.0.0 — 2026-07-22

rozeta 2.0 — A fresh new look and smarter lecture notes

• Completely redesigned app interface for a cleaner, more unified experience.
• New "@ references" and "slide grouping" — connect and organize your lecture flow section by section.
• Record without a note using "Audio only," or start recording right on top of an existing note.
• Move freely between screens while recording, with a floating dock to jump back anytime.
• Select multiple notes or recordings to delete or move to another subject in one go.
• Greatly improved transcription accuracy and consistent terminology.
• Refined handwriting responsiveness and more reliable recording & saving.
