Guide
Find a subject
Discovery is how you arrive at a subject. It is not the same as studying it.
Explore is the catalog: languages, science, culture, business, people, design, and technology. A card is a subject, not a lesson. Opening one is how study starts.
Search when you know the name. Browse and filter when you are looking around. Suggested and Serendipity are badges on cards, not a separate list of what is “best.” They use only subjects you have already started on this device.
How to
Open Explore. Use the search field if you know a name such as Psychology, Python, or UX.
Or browse the list and filter by category when you do not have a name yet.
Read the card: a short description and how many lessons it has. That is enough to decide whether to open it.
A Suggested badge comes from subjects you already started, spread across fields. A heart is Serendipity — one subject outside that path, the same pick for the day.
Press Ctrl+K (or / when you are not typing) from any page. Search finds subjects, lessons, Quizzes, Games, and these how-to pages.
What you will see
- The catalog, category filters, and a short line on each card.
- Suggested badges only after you have started at least one subject.
- One heart a day. It does not jump every time you reload.
- If you have not started anything, early suggestions lean toward business, people, and design — not a tech stack.
If you get stuck
- No results: try a shorter name, or clear the filter and browse.
- No Suggested badge yet: open any subject first. The catalog still works without it.
- Suggested is “nearby,” not a ranking. You choose what to study.
