Overview

Freiya supports two types of collections:
  • Paper collections - Group related research papers
  • Chat collections - Organize AI conversations
Both work similarly but serve different organizational needs in your research workflow.
Collection limits depend on your subscription tier: Free (2), Pro/Nova (20).

​
When to consolidate

Merge or delete collections when:

​
Troubleshooting

You’ve reached your tier limit:
  • Free: 2 collections of each type
  • Pro/Nova: 20 collections of each type
Solutions: Delete unused collections or upgrade your tier.
Papers can belong to multiple collections simultaneously:
  1. Remove from one collection if desired
  2. Add to new collection
  3. Paper exists in both places
There’s no “move” because papers aren’t limited to one collection.
Collection names must be unique per user. Options:
  • Choose a different name
  • Add differentiating details (dates, projects)
  • Delete the old collection if no longer needed
Check if:
  • You removed them accidentally
  • Papers were deleted from library (removes from all collections)
  • You’re viewing the correct collection
  • Filters are hiding papers
Yes! Export options:
  • Export all citations from collection
  • Download paper list as CSV
  • Generate bibliography for collection
  • More export options coming soon
