What is a collection?

A collection is your own structured list inside Moonjar — fields, types, and all. When you tell the assistant “make me a list of plants with watering schedules”, it builds the schema for you and starts filling it in.

Each collection has fields. Each field has a type — text, number, date, location, image, true/false, a fixed set of options, or a reference to another collection. Each collection has items, which are rows that hold one value per field.

When you add an item by chat, the assistant fills the fields in from what you described. You can also edit items by hand on the collection’s detail screen.

Collections can be reordered (drag-to-rearrange in the Collections tab), pinned with summaries, and grouped under parent collections.

When something doesn’t fit as free-form notes:

  • Books you’ve read, with star ratings and dates finished.
  • Plants you own, with light needs and watering intervals.
  • Restaurants you want to try, with cuisine and neighbourhood.
  • Anything you’d otherwise build a spreadsheet for.

Collections are different from documents — documents are things you’ve captured (a webpage, a photo, an email), with fields Moonjar extracts. Collections are things you’ve defined.

  • Collections are private by default. To share with others, see Share with a group.
  • Reference fields target a collection you have access to — your own collections, or any shared with you through a group.
  • The assistant won’t create a collection on its own — you have to ask.
