Studying shouldn't feel like a mess of open tabs, lost handouts, and last-minute panic. Clarity brings your lectures, readings, and slides into one place and does what a great tutor would: it builds a plan around your exam dates, picks the right way to learn each topic, and tells you why you're doing it. Reading one day, a video the next, a practice quiz today and a real test tomorrow. Stuck on a problem at midnight? Snap it and work through it. Upload your PDFs, slides, and recordings, or drop in a web link or YouTube playlist, and Clarity turns your content into confidence. SNAP & SOLVE ANY QUESTION Point your camera at a problem and get more than an answer. Instant solutions: snap a question from a textbook, worksheet, or whiteboard Step-by-step explanations: the full working, not just the final result The approach behind it: Clarity shows you how to spot this type of problem so you can solve the next one on your own Ask follow-ups: stuck on step 3? Ask by text or switch to voice and talk it through—same session, nothing to re-explain EVERYTHING IN ONE PLACE Upload PDFs, DOCX, PowerPoints, and audio, or import web links and YouTube playlists Smart Recording: capture lectures with real-time transcription and clean formatting Scanner: turn a stack of handwritten notes into one tidy digital document Picture-in-Picture: watch video lectures while reviewing your notes side by side YOUR PERSONAL AI TUTOR Most apps hand you tasks. Clarity teaches—it decides what you study, how, and why, then adapts as you go. Learns your exam dates, builds your path: set as many sessions a day as you want and Clarity fills them with the right tasks, all the way to finals. The right tool for each concept: reading, generated slide decks, video explainers, flashcards, practice quizzes, and test-mode quizzes—Clarity picks the one that fits. Interactive Sessions for the hard stuff: when a concept needs real back-and-forth, Clarity opens a live session—switch between voice and text anytime, like office hours with a tutor. Knows the why—and tells you: every task comes with a note explaining what it's for. Adapts every session: each one is reshaped by how the last went, moving every topic from Developing to Mastered. THE TOOLS THAT MAKE IT STICK Whether Clarity assigns them or you reach for them yourself: Chat with Clarity: ask questions about any PDF, video, or recording and get instant answers from your own materials Instant Summaries: compress long documents into tight summaries or structured revision notes Smart Flashcards with spaced repetition: reviews land right before you'd forget Adaptive Quizzes that meet you at your level: – Below 70% (Developing): drill your weak spots – 70–90% (Proficient): lock in what you know – Above 90% (Mastered): unlock Challenge Mode LOCK IN WHEN YOU NEED TO The hard part of studying isn't starting—it's not reaching for your phone five minutes in. Optional app blocking: turn it on for any session and Clarity blocks the apps that derail you. No separate app needed. A real lock, not a nudge: your chosen apps stay shut until the session ends—with an emergency unlock if you need it. You set the rules: pick which apps to block and how strict to be. STUDY ANYWHERE, EVEN WITH THE SCREEN OFF Turn your commute or workout into study time. Audio Recap: pick the topics you want from any document and Clarity turns them into a podcast-style episode for the walk to class Background Play: keep listening to recordings, recaps, and revision notes with your phone locked or in other apps Text-to-Speech: turn any note into clear, natural audio STAY MOTIVATED Streaks & XP: build a daily study habit and earn rewards Achievements: unlock milestones as you master new subjects Smart Nudges: timely reminders to revisit a topic before it slips Download Clarity today and turn your content into confidence.

Verdict
The clearest difference is review sentiment: ClarityStudy at 100% against Knowt's 62%. Knowt's advantage is ratings volume (11K vs 4) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases 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. Knowt sells 9 in-app purchases, starting at $9.99 per 7 days and ClarityStudy sells 6 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
Knowt holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Knowt has 11K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 62% of Knowt's written reviews are positive against 100% of ClarityStudy's, so the app with the better star average is not the one people write more warmly about.
Knowt ships an update weekly, ClarityStudy every 10 days. The most recent releases landed on November 10, 2026 and October 30, 2026 respectively.
