Market

Updated on August 5, 2026

The Market is where students share problem collections with the rest of the community. You can browse what others have published, preview the problems before committing, and clone any collection to your account in one click.

Browse collections

Open the Market from the navigation bar. By default you will see the Browse tab with the most-cloned collections in your language. Use the selector in the top-right corner to change the order: Most cloned or Newest.

Search by author or tag

The search bar accepts three kinds of input:

  • Free text — searches collection titles and descriptions.
  • @username — filters collections published by that user.
  • #tag — filters by a specific tag.

You can combine them in a single search, for example: integrals @professorx #calculus.

Preview before cloning

Click any card in the Market to open the preview. There you will find:

  • The Structure of the collection: the tree of folders and sub-collections.
  • Sample problems: a selection of the actual problems inside.

Toggle Include subcollections to also see problems from sub-folders as you navigate the tree.

Clone a collection

From the preview, click Clone to my account. A confirmation dialog appears; confirm and the collection will be available in My problems, ready to use.

You cannot clone your own publications. If you try to clone a collection you published, the app will let you know.

Frequently asked questions

Does a cloned collection update if the author changes it? No. Cloning creates an independent copy. Changes made by the original author do not affect your copy.

Can I search for collections in another language? The default browse shows collections in your language. When you search with free text, @username, or #tag, results may include other languages.

What does the clone count on a card mean? It shows how many times that collection has been cloned by other users. A high clone count is a good sign that the collection is useful.

Is there a limit on how much I can clone? The number of problems you can have depends on your plan. SimuLab warns you before cloning if the collection would exceed your available limit.
