Hey, I'm Knowie - your new way of learning. Whatever you're working on, I'll help you understand it, remember it, and walk into your next SAT, ACT, or AP feeling ready. 30 million students already study with me, I am created by the best students and the core tools are free. This is a the new way of learning - here is how we do it. Everything runs through one place: your exam plan. Instead of a pile of separate features, I pull it all together - flashcards, quizzes, summaries, mock exams, voice practice, and the official SAT, ACT, and AP guidelines - and structure it into a day-by-day plan built around your test date and your topics. Your exam plan, made with you. Tell me when your test is and what you need to cover, and I'll map out exactly what to do each day, with the right notes and flashcards for your course. Add your class timetable and I'll fit study around your lessons - no all-nighters. As the test gets closer the plan adapts, and you always see what you've got down and what's next. Study that actually sticks - active recall. Rereading feels productive but fades fast, so your plan is built around active recall: pulling answers out of your own memory. Quizzes and flashcards ask you to remember, not just recognize, and mastery tracking shows each topic move from shaky to solid. Just say it out loud. This is where voice comes in. With voice recall in your plan, you say your answer from memory and I check it with you - hands-free, out loud, the way real recall works. And in chat, switch on voice mode to talk to me like a tutor: ask anything, no typing needed. Stuck on homework? Snap a photo of any problem - math, chemistry, physics, biology - and I'll walk you through it step by step, so you get the how, not just the answer. Keep a separate chat for each class so nothing gets mixed up. Turn anything into study material. Upload PDFs, slides, photos, or handwritten notes, paste in text and links, bring your old flashcard decks, or drop in a YouTube video - I'll turn it into flashcards, quizzes, and clean summaries in seconds, ready to slot straight into your plan. Need vocab for a language class or a clearer essay outline? I've got you there too. Practice like it's the real thing. Take full, AI-scored mock exams in real SAT and AP format and see where you stand before test day - then I fold the results back into your plan, so you review exactly what needs work. Learn from real students. Browse over 1 million notes, summaries, and past-paper solutions shared by students in your subject and grade - right alongside everything we make together. Keep your streak going. Earn XP as you study, join a weekly league of up to 30 classmates, and climb from Bronze to Gold. A little friendly competition to keep you coming back. I'm built for every subject - AP courses, Math, Sciences, Social Studies, English, World Languages, Computing, and SAT and ACT prep. Whether you're cramming tonight or planning weeks ahead, we'll get you there - and the core tools are always free. Ready when you are. Download Knowunity, and let's study smarter, not harder.

Verdict
The clearest difference is ads: Kiwi AI at none against Knowunity's shown. Knowunity's advantage is update cadence (daily vs every 10 days) and review sentiment (82% vs 57%). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Knowunity sells 8 in-app purchases, starting at $9.99 per 7 days and Kiwi AI sells 10 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Knowunity against 4.7 for Kiwi AI. That said, the two scores are not equally well evidenced: Knowunity has 12K ratings behind it against 574, so its average is the more settled of the two. Written reviews are what separate them: 82% of Knowunity's written reviews are positive against 57% of Kiwi AI's.
Knowunity ships an update daily, Kiwi AI every 10 days. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
