Frequently asked questions
Our review notes are written to mirror the current digital SAT's content and skill categories. Practice questions are original — written or AI-generated and verified against the correct answer before publishing — never copied from real College Board material. Every question has a report button if something looks off.
Yes. Pro is billed monthly or annually with no lock-in — cancel from your billing settings whenever you like and you'll keep Pro access until the end of your current billing period.
PDFs, audio recordings (lectures, voice memos), YouTube links, images of handwritten or printed notes, and plain text. Primer transcribes and reads all of it before generating notes.
Primer scripts a natural two-host discussion of your note set using AI, then converts that script to audio — so you get a listenable recap instead of a robotic read-through of your notes.
Your documents, notes, and generated content are private to your account. We don't use your material to train models, and you can delete any document — and everything generated from it — at any time.
Free is capped: 2 uploads and 2 flashcard/quiz generations a month, 15 SAT practice questions, and no mock exams or podcast mode. Pro removes those caps entirely and unlocks the full SAT question bank, mock exams, and podcast mode.
