For Teachers
Your Files
The file library — where your uploaded lessons live, how to reuse the same file in another class, how to pick which files the AI reads, and how to delete one.
Every file you upload stays in Your files, in the left menu. It belongs to you, not to one class, so the chapter you upload for 3A this morning is ready for 3B this afternoon without uploading it again.
Students never see these files. They only ever see the cards you approve.
What can go in
PDF, PowerPoint (.pptx), Word (.docx), plain text and Markdown, or a photo of a page (.png, .jpg, .webp).
Each file can be up to 10 MB and 100 pages or slides. Your library holds 200 MB in total — the bar at the top of the page shows how much room is left. One assignment can use up to 3 files at a time.
If a PDF is password-protected, remove the password first. If a chapter is longer than 100 pages, split it or export the part you are teaching.
Reusing a file in another class
In the assignment wizard, under the upload box, open Reuse a file you uploaded before and click Add. The same file can feed as many assignments as you like, in any of your classes. Nothing is copied and nothing is uploaded twice.
On the library page, each file lists the assignments it is being used in, with the class name — so you can always see where a lesson has ended up.
Choosing which files the AI reads
When an assignment has more than one file, each one has a tick box in the Your files panel on the assignment page. Only the ticked files are read the next time the AI writes cards.
That is useful when you have attached a chapter and a worksheet but want the next batch of cards to come from the worksheet alone. Leaving a long file out also saves AI credits, because the AI has less to read.
Removing a file from an assignment (the × next to it) does not delete it — it stays in your library.
Making more cards without repeats
When you ask for more cards on an assignment that already has some, the AI is given the questions already in the deck and told not to repeat or reword them; it looks for parts of the material the deck has not covered yet. The same happens when you swap a single card: the rest of the deck is protected, and the new card has to test something different.
Regenerate the whole deck is the exception — it throws the old cards away and starts again, so it is only offered while an assignment is still a draft.
Deleting a file
Click Delete on the library page. If the file is used by an assignment, you are told which ones before you confirm.
Deleting is safe for your students: every card already written stays exactly where it is, in the deck and in each student’s park. You just cannot make new cards from that file afterwards. Cards are yours once they are written; the file is only the source they came from.
Who else can see them
Nobody. A file library belongs to one teacher account. A co-teacher you invite into a classroom can see and edit that classroom’s assignments and cards, but not your file library.
If you and a colleague want to work from the same chapter, upload it to each account for now — a shared team library is not part of the beta.
