Yes, to start. Gizmo's help center says cards, decks and quizzing are free. The free plan has limits: after you lose 15 Hearts while quizzing you wait 10 minutes, Magic Import is limited to 2 a day with a 20-minute wait between imports, and you get 5 AI Tutor sessions a day. Gizmo Unlimited removes them. StudyPDF is free to start too: a free account, no credit card and no time limit, with about 4 materials a week.
Gizmo has two paid Unlimited plans: a yearly one (Long-term) and a weekly one (Last minute). Its help center lists no price, because the price is shown in the app by device and region, so check it there before you subscribe (as of October 2026). Subscriptions renew automatically until you cancel, and a student discount can show up if you qualify. StudyPDF's Free plan costs nothing. Pro and Ultra add a bigger weekly pool of materials.
Gizmo is a friendly study app. On its own site it turns PDFs, notes, YouTube links and recordings into flashcards and quizzes, schedules reviews with spaced repetition, has an AI Tutor, and adds XP, streaks, leagues and live multiplayer quizzes. It is a good fit if you like game-style studying and quick decks. Pick StudyPDF if you want answers cited to the page, one concept map across your whole course and graded practice exams.
Yes, if you want a tool built around your whole course, with answers cited to the page, full graded exams, mind maps, study guides and cheat sheets, and per-concept progress tracking. Both make flashcards and quizzes from your files and have apps for iPhone and Android plus the web. Gizmo adds live games and a playful reward system, while StudyPDF goes deeper on your own course material.
It cites the page behind every answer, maps your whole course into one connected concept graph, writes full graded practice exams with a pass mark, builds mind maps, study guides and cheat sheets, tracks per-concept mastery, and plans your revision up to the exam date. It also exports to PDF on every plan, and to Word and Anki on Pro and up.
Gizmo runs live multiplayer quizzes on any deck with a game code, rewards you with XP, levels and leagues, and imports Quizlet and Anki decks. StudyPDF has no game mode. It reads the files you upload, including photos and scanned or handwritten notes, plus YouTube links and websites.
It is free to start. Free gives you about 4 materials a week and 2 courses. Pro adds about 35 a week and 10 courses, and Ultra adds more, for heavier exam-season use. Every plan has weekly caps, and you only upgrade when you outgrow the free plan.
Upload your course and ask Bo anything. No card required.
