How money works here
- Do I need to pay to build projects?
- No. Discovering, starting, building, recording data and finishing a project are all part of the free Explorer experience.
- What is a premium project?
- A creator can choose to charge for access to their project template and instructions. The price is always shown on the card and the project page — never hidden.
- How do creators get paid?
- Free Explorer creators keep 80% of every premium sale (20% platform fee). Scientist subscribers keep 85% (15% fee). The fee covers payment processing, hosting, moderation and support. Earnings are held briefly in case of refunds, then paid out to the creator's connected payout account.
- Which fee applies to my sale?
- The fee is locked in by our servers at the moment a sale is created, based on your plan at that time, and stored with the sale record. Changing plans later never changes a past payout.
- Does the AI do the project for my child?
- No. Every measurement is entered by the builder and all statistics are calculated from those numbers. The assistant only explains concepts and asks guiding questions.
