Yes, and it refills every day rather than running out after a week. You get the tutor, notes, practice questions, the planner and the career guide without a card. Every tool shows what you have left before you use it.

PDFs, Word files, PowerPoint, plain text, photos of handwritten pages, and audio recordings up to about fifteen minutes. A scanned PDF has no text in it, so upload those pages as images instead and it reads them with vision.

They are stored privately against your account and read only to answer your questions. Delete a file and both the file and the text taken from it go. Nothing is shared with other users.

One click from your account page, which opens the billing page where you cancel yourself. You keep Premium until the end of the period you already paid for, and nothing is charged after that.
