Collection

Collections are smart filters that automatically aggregate content based on rules.

Imagine you're organizing a study room

• Topic = Work desk - Projects in progress, materials spread on the desk, discuss with assistant (AI) anytime
• Folder = Bookshelf - Books organized by category, take them out when needed
• Collection = Smart search - "Find all books about AI", automatically gathered from everywhere

Collection Features

• Automated - Automatically filters after setting rules.
• Dynamically updated - New content that matches rules automatically appears.
• Cross-folder - Aggregates content from all places.

How to Use Collections

Create Collection

1. Click the Collection button on the left, then click New.
2. Set filtering rules (type, keywords, time, etc.)
3. After clicking confirm, the collection will automatically display all content that meets the criteria.

Common Scenarios:

• "Last 7 days notes" - Track recent active content.
• "Today's clips" - Aggregate articles saved today.
• "All content about AI" - Automatically aggregate by keywords.
• "Specific tags" - Aggregate all content of a certain topic.
• "Inbox" - Built-in Dessix collection for storing content to be organized.
