👋 Hi, I'm J Young

I build Fileloom, a free Android reader app for opening, viewing, and listening to files more comfortably.

리더(Reader)앱 이면서, 파일을 더 편하게 열고, 보고, 다룰 수 있는 무료 앱 파일룸을 만들고 있습니다.
개선 아이디어, 버그 제보, 사용 후기, TTS 모델 제안 등 모두 환영합니다.

🧵 Fileloom

• 📄 Read · 읽기 — PDF, EPUB, MOBI, FB2, Office documents, HWP, RTF, Markdown, HTML, and plain text/code with syntax highlighting
• 🔊 Listen · 듣기 — built-in TTS turns your documents into audiobooks
• 🖼️ View · 보기 — images including PSD and Adobe Illustrator files, plus audio, video, and CAD previews
• 🗜️ Browse · 탐색 — ZIP/7Z archives without extracting, local files, and cloud storage
• 📤 Share · 공유 — send files between devices with Transferloom

Built with Kotlin and Jetpack Compose.

🧩 Open source

Parser cores powering Fileloom, released as standalone Kotlin libraries.
파일룸에 들어가는 파서 코어들은 오픈소스로 공개하고 있습니다.

• fileloom-pdf-core — PDF content/text extraction
• fileloom-pdf-security-core — pure Kotlin PDF security/decryption
• fileloom-rtf-core — Rich Text Format parsing
• fileloom-psd-core — Photoshop PSD/PSB parsing and rendering
• fileloom-ai-core — Adobe Illustrator parser and layered SVG renderer
• fileloom-step-lite — dependency-free STEP/STP preview parser

Also tinkering with superloopy, a loop harness for Codex/Claude with strict evidence gates, and labradorcli, a fully local agentic CLI.
