One-liner
A minimalist, fast PDF reader with seamless note-taking and sync, optimized for Obsidian users who want a lightweight alternative to heavy-duty note-taking apps.
Strengths
- Fast, smooth rendering of large PDFs with minimal lag (review: 'opens instantly even with 500-page docs')
- Seamless integration with Obsidian via local file sync (review: 'syncs perfectly with my Obsidian vault')
- Clean, distraction-free interface focused on reading and annotation (review: 'no clutter, just text and notes')
- Supports Markdown export of highlights and notes (review: 'I can easily move my annotations into Obsidian')
- Lightweight and efficient use of system resources (review: 'runs smoothly on my old iPad')
Weaknesses
- No cloud sync beyond local file sharing (review: 'would love iCloud or Dropbox support')
- Limited collaboration features (review: 'can’t share annotated PDFs with others easily')
- No built-in search across multiple PDFs (review: 'search only works within one file')
- No OCR support for scanned documents (review: 'can’t read text in image-based PDFs')
- No dark mode toggle (review: 'bright white background hurts my eyes at night')
Opportunities
- Add optional cloud sync (iCloud/Dropbox) to enable cross-device access without compromising privacy
- Introduce batch search across multiple PDFs in a folder, ideal for researchers and students
- Implement OCR for scanned PDFs using Apple’s Vision framework to unlock text extraction
- Build a dark mode with customizable themes to improve nighttime reading comfort
- Create a simple sharing feature that generates a link to a shared annotated PDF (e.g., for study groups)
