OpenCards — Organize Your Knowledge

Turn your Markdown notes into beautiful, browsable knowledge cards. OpenCards helps you organize, review, and carry your knowledge everywhere.

Organize Your Way
Create sections to group your cards by topic — class notes, research papers, vocabulary, or anything you need. Browse cards in a smooth horizontal carousel or search across your entire collection instantly.

Rich Markdown Rendering
OpenCards renders full Markdown with support for math equations (KaTeX), syntax-highlighted code blocks, tables, and more. Your content looks great in both light and dark mode.

Tag, Like & Filter
Mark your favorite cards with a like. Add tags to categorize and find cards quickly. Filter any section by likes or tags to focus on what matters.

Full-Screen Reading
Tap any card to enter an immersive full-screen view. Swipe through cards one by one — perfect for studying and review.

iCloud Sync
Your cards sync automatically across all your devices via iCloud. Start on your iPhone, continue on your iPad.

Import from GitHub
Paste a GitHub folder URL to bulk-import Markdown files directly into any section. Great for pulling in shared notes, study materials, or documentation.
