From paper books to passages of your own Underline the words that stay with you. Let each passage grow into a thought of your own.
종이책에서 만난 문장을 나만의 글조각으로 마음에 남은 문장에 밑줄을 긋고 나만의 글조각으로 간직하세요. 한 조각씩 쌓인 문장들이 나만의 생각으로 성장합니다.
紙の本で出会った一文を、自分だけの言葉のかけらに 心に残った一文に線を引いて、大切にしまっておきましょう。 集めた言葉が、少しずつ自分の考えに育っていきます。
Have you ever wanted to underline a sentence or jot down a thought while reading, but hesitated because you wanted to leave the book unmarked?
BZOGAK is a mobile app for capturing passages you love, keeping reading records, and getting more out of your reading with AI.
When your eyes feel tired, or you want to hear a little more of the story before falling asleep, try AI narration. Photograph the pages you are reading and enjoy your paper book like a personal audiobook.
You no longer have to wonder where you wrote down that favorite passage. Find it with a quick search, then explore your saved passages with AI to discover insights of your own.
- Underline and save: Draw a line with your finger over the sentences you want to keep on a captured page, and save them as text. There is no need to copy them out or mark the book itself.
- Listen to captured pages: Photograph one or several pages and listen to them continuously with on-device narration, even while the screen is locked or you are using another app.
- Bookshelf and search: Organize passages and notes by book, then search titles, tags, and notes to find the records you need.
- Reading records: Keep track of reading dates, progress, ratings, and reflections for each book.
- AI reading notes and insights: Use saved passages to draft a book reflection, ask questions about a book, summarize its content, and organize your thoughts.
- Community and book information: Browse popular books and blog posts about what you are reading, or find nearby bookshops and libraries.
종이책을 읽다가 밑줄을 긋거나 메모를 하고 싶은데, 책에 흔적을 남기고 싶지 않아 망설였던 적 없으신가요?
글조각 서랍은 책을 읽다가 마음에 든 문장을 캡처해서 글조각으로 저장하고, 독서 기록을 관리하며, AI와 함께 독서 경험을 확장하는 모바일 앱입니다.
책을 읽다가 눈이 피로할 때, 잠들기 전 읽던 이야기를 조금만 더 듣고 싶을 때는 AI 나레이션을 활용해보세요. 읽던 페이지를 촬영하면 종이책도 나만의 오디오북처럼 즐길 수 있습니다.
마음에 드는 구절을 메모해두고도 어디에 적었는지 찾지 못했던 번거로움도 줄어듭니다. 원하는 문장을 검색으로 다시 꺼내보고, 모아둔 글조각을 AI와 함께 살펴보며 나만의 인사이트를 발견해보세요.
- 밑줄긋기: 촬영한 책 페이지에서 원하는 문장에 손가락으로 밑줄을 그어 텍스트로 저장합니다. 문장을 일일이 옮겨 적거나 책에 직접 표시할 필요가 없습니다.
- 페이지 읽어주기: 한 장 또는 여러 장을 촬영해 기기 내 음성으로 연속해서 듣습니다. 화면을 잠그거나 다른 앱을 사용하는 동안에도 재생을 이어갈 수 있습니다.
- 책장과 검색: 글조각과 메모를 책별로 모으고, 제목·태그·메모로 검색해 필요한 기록을 찾습니다.
- 독서 기록: 책마다 읽은 날짜와 진행 상태, 별점과 감상을 함께 기록해 독서 이력을 관리합니다.
- AI 독서 메모와 인사이트: 모아둔 글조각으로 독서 감상문 초안을 만들고, 책에 관해 질문하거나 내용을 요약하며 생각을 정리합니다.
- 커뮤니티와 책 정보: 인기 도서와 읽고 있는 책에 대한 블로그 글을 살펴보고, 가까운 서점과 도서관을 찾아봅니다.

| Optional local AI narration | Supertonic 3 with ONNX Runtime 1.24.2 |
| On-device text correction | Apple Foundation Models on supported iOS 26+ devices |
| Optional external AI | OpenAI, Anthropic, Gemini, OpenRouter |

Use Xcode 26.6, the toolchain used to verify this project, and a physical iPhone running iOS 17.0 or later for camera and audio testing.
git clone https://github.com/hsu3046/OverlineAI.git
cd OverlineAI
open Overline.xcodeproj- Select the
Overlinescheme. The built app is namedBZOGAK. - Configure your own signing team and a bundle identifier available to that team.
- Select your iPhone and build and run the app. Allow camera or microphone access when using the corresponding features.
The project and source directory retain the internal name Overline. The public product name is BZOGAK / 글조각 서랍.
- External AI: Configure a provider and your own API key in the app, then consent to sending selected content. Provider charges may apply independently of the free app.
- High-quality local narration: Download the optional Supertonic voice model from the app before first use. Once downloaded, narration runs on the device without an internet connection.
- Community API: Follow the backend setup guide to deploy your own service. Provider credentials belong in server environment variables, not in the iPhone app. Use the configuration example to override the app's API base URL locally.
Run the focused library-backup, in-flight insight, and legacy credential cleanup tests from the repository root:
bash Tests/LibraryBackupCodec/run.sh
bash Tests/LibraryContentRevision/run.sh
bash Tests/LegacyCredentialCleanup/run.shAfter installing the backend dependencies as described in its setup guide:
cd CommunityAPI
npm run typecheck
npm testCamera capture, speech generation, interruptions, and background playback should also be tested on a physical iPhone.
