Quizlet sells Plus at $35.99 a year and Plus Unlimited at $44.99 a year when billed annually in the US, as of October 2026. A Family plan for up to 5 accounts is $83.99 a year. Prices vary by country, billing period, and app store, so check Quizlet's own pricing page before you subscribe. StudyPDF's Free plan costs nothing. Pro costs $11.99 a month or $47.99 a year and Ultra $19.99 a month or $95.99 a year on the web, with a bigger weekly pool of materials.
Yes, if you want a tool built around your own course rather than generic study sets. StudyPDF cites the page behind every answer, maps your whole course into one connected concept graph, writes full graded exams, exports flashcards to Anki and fold-over PDFs, and tracks per-concept mastery. Quizlet is still great if you mostly want ready-made sets and quick study games.
It cites the page behind every answer and refuses to make things up, maps your whole course into one connected concept graph, writes full graded practice exams with sections and a pass mark, imports your slides, scans, and YouTube links, builds mind maps and cheat sheets, exports to Anki, and tracks per-concept mastery so it knows what to study next.
Quizlet has millions of ready-made study sets from other students that you can search and use right away, plus casual study games like Match. StudyPDF builds everything from your own uploaded course material instead.
It is free to start, and the free tier gives you about 4 materials a week. Pro and Ultra add a bigger weekly pool of credits for heavier exam-season use. You only upgrade when you outgrow the free plan.
Upload your course and ask Bo anything. No card required.
