Groups & Editor
Organize knowledge with hierarchical groups and create cards with a powerful editor supporting Markdown, LaTeX, images, and audio.
Paste content from clipboard — split front/back by line. Supports Markdown, LaTeX, images, and audio inline references.
Insert images and audio into cards. Images are auto-compressed (2560px, JPEG 80). Files stored with MD5 deduplication.
Organize cards into multi-level groups. Each group shows card count, new cards, and due cards at a glance.
Full-text search across thousands of cards. Find and edit any card in milliseconds.
FastPasteEditor
The editor is designed for speed. Paste a block of text from a webpage or document, and click the line number to separate front and back. Multiple paste modes are available:
- Append mode — add content without overwriting
- Overwrite mode — replace current content
- Overwrite & Save — replace and save in one click
Markdown & LaTeX
Card content supports full Markdown rendering. Code blocks with syntax highlighting and LaTeX math formulas (via $...$ or $$...$$) are rendered inline during review.
Multimedia
- Images: pick from file system, auto-compressed with MD5 deduplication
- Audio: embed audio players directly in cards for listening practice
- Reference format:
[media:image:filename.jpg]or[media:audio:filename.mp3]in card text
Group Management
Groups appear as an expandable tree in the UI. Each group has a color indicator and displays:
- Total cards
- Active (non-deleted) cards
- New cards waiting for first review
- Due cards ready for review today
Batch operations include multi-select cards to move them between groups or delete in bulk.
