Public decks
You don't have to study only what you build yourself. You can share your decks and study the ones other people have made public.
Sharing a deck
Every deck has a visibility. In Public it becomes visible to anyone, with or without a Medkit account: it shows up in Explore and on your profile, opens with the link, and may show up in search engines like Google. Whoever opens it sees all of its cards and can clone it, but editing it, deleting it and studying it as is are still only yours. In Private only you see it: the link is no use to anyone else.
You can also pick up to 3 categories (Medicine, History, Programming...). They are optional, but they are what lets people filter it in Explore: without any, the deck is found by searching its name and little else. There are several because a deck can belong to more than one area: a professional ethics deck can be both Law and Engineering, and it shows up under both. Type in the field to search for the one you want, and if none of them fits pick Other and write what it is about: that is how the missing ones get added. They are chosen only on the top level deck, and subdecks inherit them, same as the visibility.
A deck also carries a language, the one its cards are written in, and that one is required to publish it: a deck written in a language you cannot read is useless even if the topic is exactly the one you wanted. If the deck teaches a language, pick the one the prompts are written in. It is chosen only on the top level deck and subdecks inherit it, same as the categories. While the deck stays private you can leave it unset.
Every deck can carry a colour, and that colour travels with it: it looks the same in your own deck list and in Explore. Unlike the category, any deck can have one, subdecks included.
You can also upload a cover: the image that stands for the deck in your deck list, in Explore, on your profile and at the top of its page. It needs to be at least 600 pixels wide, because on the deck page it spans the whole screen. Since it gets cropped differently in each place, drag the control on the side or any of the three views to pick which part stays visible: the whole image is kept, so you can reframe it later without uploading it again. Any deck can have one, subdecks included, and whoever clones it takes it along. A deck with no cover isn't left blank: in full view it shows its colour.
You don't need to hunt the deck down to change any of this later: the three-dot menu has Edit in your deck list and on your profile, and its own page in Explore has an Edit deck button. They all open the same window, where you can also set it back to private.
You don't need to copy the address bar to pass a deck along: its page has a Share button. On a phone it opens the system menu, so you can send it straight to WhatsApp or wherever. On a computer it copies the link.
Discovering other people's decks
Other people's public decks don't mix in with yours: they live in Explore, in the top bar, with the ones from all of Medkit. There you search them by name and filter them by category and language. You also reach them from the profile of whoever created them, and either way you land on the same deck page: that's where you browse the cards, like it or clone the deck. The page carries the author, three numbers, and the mix of card types, which isn't decoration: two decks of 1240 cards aren't the same thing if one is all Front/Back and the other has half of it in Hidden words. The three numbers are: how many cards, how many subdecks and how many parts (every hidden word, rectangle, tag or zone is reviewed on its own, so a single card can contribute several).
Explore opens with or without an account, so you can browse decks and read their cards before signing up. What does need an account is cloning, liking, commenting and studying.
The list starts sorted by most cloned. Searching by name and changing the sort order are immediate: they filter the decks already on screen, with nothing to reload.
The Filters button opens two groups, categories and language, with only the options that have at least one published deck and the count next to them, so none of them leaves you on an empty list. You can tick several: within a group they add up (Medicine and Nursing brings both) and across groups they cross (Medicine in Spanish brings only those). Whatever you ticked stays visible below the bar even with the panel closed, and can be removed one at a time. There are also No category and No language, and a deck with three categories shows up under all three. Filters travel in the page address, so you can share an already filtered search.
The view button switches between full and compact. The compact one keeps the name, the deck's numbers and its tags. The full one adds the description. It is the same preference here and on a profile's public decks, and on narrow screens the list is always compact. Your own decks keep their view separately.
Every deck shows how many likes it has and how many people cloned it. Clones count people, not times: someone who clones the same deck twice still counts as one.
Cloning a public deck
If a public deck is useful to you, you can clone it. That creates your own private copy, with all its subdecks and cards, which stays synced with the original and which you study like any other deck.
You don't have to take all of it. On the deck's page, and on a profile's list of public decks too, every subdeck has its own Clone button: if all you want out of a whole subject is one midterm, clone that one. To decide which, each deck's three-dot menu opens Details, with its description, what it holds, and its language and categories (a subdeck inherits its main deck's).
The copy is born synced: while it is, it cannot be edited, and in exchange it stays up to date with the original. When you want to make it yours, edit, move or delete something and Medkit asks whether you want to cut the sync.
The detail of how cloning works (where the copy appears, what is copied and what isn't) is in Organizing your decks and cards.
Comments on a deck
Below a public deck's page there are comments: to say thanks, flag a mistake in a card, or ask something before cloning it. Anyone can read them without an account, same as the rest of the page, but you need to sign in to write.
They always live on the main deck, not inside each subdeck or on the cards. A large deck can have hundreds of subdecks, and scattering the conversation in there is the same as not having one. You can reply to a comment, but only one level deep: no replies to replies.
Any comment can be reported if it's out of line. It can be deleted by its author, by whoever made the deck, or by the Medkit team. And when someone comments on a deck of yours you get a notification in the bell.
Reporting a deck
If a public deck has something that shouldn't be there, its page has a three-dot menu next to Clone with Report deck. You tick one or more reasons and can add details. The report goes to the Medkit team, not to the author: they aren't told that their deck was reported or by whom.
That report is about the deck's content. If the problem is the person (their username, their profile picture, or an account that only posts spam), the report goes from their profile. And a comment that's out of line gets reported from the comment itself, not from here.
If a deck of yours is taken off public
When a public deck has something that can't be there, an administrator switches it to private. Nothing is deleted: the cards, your progress, the likes and the comments stay as they were, and you keep studying and editing it the same. What changes is that it's no longer public and you can't publish it again.
The reason goes in an email, and that's the only place you'll read it: inside the app it only says the deck was taken off public. You also get a notification in the bell, and when you edit the deck you'll see the visibility selector turned off. If you think it was a mistake, write to the address the email gives you: an administrator can lift the restriction, and from there the deck stays private until you publish it again.
