POP! Math Cards quizzes you with fun math flash cards across a variety of game modes for addition, subtraction, multiplication/Times Tables multiples, and division! Play fun quizzes with colorful comic style backgrounds and music, and show off your progress across games with your “Study Goals” level meter that increases with correct quiz answers! As you level up, you can unlock more backgrounds and colors to decorate your games with! You can also level up even more by playing weekly Study Goals objectives, where POP! Math Cards creates 2-4 weekly goals based off of which types of math (or Times Table multiples) that you are currently learning! Parents/Educators can appreciate that various parts of the game adjust their difficulty to the player’s performance, in order for players to better learn. (Weekly Study Goal objectives change their difficulty based on player performance, and multiplication quizzes prioritize repeating problems that the player gets stuck on.) POP! Math Cards is also designed to be accessibility friendly, with VoiceOver support, Large Text support, and various game settings such as “Training Wheels” (where you can try again if you pick the wrong answer in a quiz, but without increasing your score). Improve your math skills while having fun with POP! Math Cards!
Anti/Agent

Save is not the same as learn. A chat answers and forgets. Anti/Agent is the opposite: every page you build comes back and teaches you, on the day you'd otherwise forget. It's an AI notebook for both knowledge and skills. Drop in sources, write your thinking, and choose how each page should return. HOW A PAGE IS BUILT - Sources: drop anything in. URLs, PDFs, YouTube, audio, past pages. Read, indexed, ready to cite. - Editor: a real editor, not a chat. Blocks, formatting, drag-to-reorder, a slash menu. - AI partner: highlight, ask, and the AI streams a researched, cited section right into the page. THREE WAYS A PAGE TEACHES YOU BACK - Memory: flashcards in your own words. You type the answer in plain English and the AI grades it like a teacher. Spaced repetition (FSRS) books the next review for the day your memory is about to slip. - Thinking: dialogues that talk back. Debate a claim, rehearse a mock interview, hold a conversation in a new language, or explain an idea to a curious learner. Each session comes back a little harder. - Skill: exercises with your own rubric. You set the standard in the page; the agent grades your attempt against your bar, not generic correctness. WHY IT STICKS Recognizing an answer and producing it from memory are different skills. Anti/Agent removes the gap between writing something down and being asked about it later, so understanding a source and remembering it stop being two separate jobs. SHARE AND LEARN TOGETHER Make a page public when you're proud of it. Start your own from a page somebody else shared. Spaced repetition keeps pulling either of you back. LEARN ANYTHING Screenwriting. Japanese, French, Mandarin. Python, Rust, ML. Philosophy. Music theory. Anything you can write a page about. FREE TO START 100 credits every month, no card required. Unlimited pages and every learning block on the free plan. PRIVATE BY DEFAULT Your content is never used to train AI models, never shared with third parties, and stored on encrypted infrastructure. Delete everything any time. GO FURTHER WITH A SUBSCRIPTION Optional auto-renewable subscriptions unlock more monthly credits: Starter ($9.99/month) and Pro ($24.99/month). Prices may vary by region.
