Is Knowt Free? The Free Plan Limits and Ultra Costs

Is Knowt Free? The Short Answer

Knowt is free for core flashcards and five study modes, while AI features beyond the free caps need a paid subscription. In the guides we publish at Chalkbox, we pull figures directly from official documentation so students can budget their study tools without surprises. The free student plan on Knowt includes unlimited flashcard sets, unlimited notes, and full access to standard study modes. AI summaries are the exception. The free tier allows one per month.

Students who need continuous access to AI tools must upgrade to the paid tier, known as Knowt Ultra. As checked in October 2026 on that plans page, Knowt Ultra costs $24.99 billed monthly or $149.99 billed annually. The annual plan comes with a 3-day free trial before the full yearly fee charges. Prices and promotional terms can change, so confirm them on the Knowt plans page linked in the first sentence before you pay.

What Knowt Is and How It Works

Knowt is a digital study application designed to help learners turn notes, documents, and videos into review material. According to the Knowt Google Play listing, the app lets students create manual flashcard sets, convert lecture notes into practice tests with artificial intelligence (AI), and study via spaced repetition. It also offers pre-made study guides for Advanced Placement (AP) courses.

Knowt runs in a web browser, on iOS and Android, and on Mac. The Knowt App Store listing notes compatibility with iPhones, iPads running iOS 16.4 or later, and Mac computers with Apple M1 chips or newer running macOS 13.3 or higher.

The mobile listing highlights that students can import sets directly from popular study sites like Quizlet. Once materials sit inside your library, you can study them in five modes at no cost: Learn, Practice Test, Spaced Repetition, Match and Flashcards.

Teachers can also set up classes inside Knowt. Instructors get access to assessment creation tools, chat-based tutoring interfaces, and interactive review games through Knowt Play. If you want to make quick decks online without an account, our free flashcard maker builds simple printable cards immediately.

Free Plan Limits and Paid Upgrades

While the basic plan provides generous storage, it places tight caps on automated learning tools. According to the Knowt student help article, free accounts receive exactly one AI summary per month. This single credit applies across uploaded Portable Document Format (PDF) files, images, video links, PowerPoint presentations, or live lecture recordings. A second summary in the same month needs Knowt Ultra.

Free accounts also encounter study ceilings on standardized test content. Free users receive one full-length mock exam across AP, SAT, and ACT materials, alongside five practice-room sessions. The free tier also shows ads.

Upgrading to Knowt Ultra removes these workflow restrictions. The paid plan removes ads and adds the AI podcast generator, lecture recording summarizer, and an AI voice tutor across all personal files. It also includes full access to AP, SAT, and ACT prep.

The student help centre lists Ultra at $24.99 per month billed monthly, or $149.99 per year, which it describes as about $12.50 per month. On the web plans page, Knowt displays the annual plan as $12.99 per month billed as $149.99 upfront. On iOS, in-app purchase options show varied price tiers. The US App Store lists weekly student options at $9.99, monthly tiers from $14.99 to $24.99, and annual tiers ranging from $59.99 to $149.99, which may represent promotional testing. Which of these a US iPhone user sees is not published.

Teacher accounts follow a separate pricing path. As detailed in the Knowt teacher help article, the free teacher tier allows file creation, live collaboration, and storage for up to 20 cumulative files. That newer article lists Teacher Ultra at $199.99 per year with a 30-day free trial, removing file limits and adding learning management integrations for Google Classroom and Canvas. An older help entry at Knowt teacher account differences lists Teacher Ultra at $19.99 monthly or $120.00 annually, so the current teacher price is unclear.

For entire schools, bulk purchasing is an option. The Knowt school pricing page states that licenses can cost as low as $4 per student, requiring an official quote request. The site notes that Knowt signs Data Privacy Agreements (DPAs) at no charge and lists the Family Educational Rights and Privacy Act (FERPA), Children's Online Privacy Protection Act (COPPA), and New York State Education Law 2-D.

Before entering payment details, understand the renewal and cancellation rules. Under the Knowt terms of use, subscriptions renew automatically for successive periods of equal duration unless cancelled. You can cancel by navigating to Settings, clicking Your Plan, selecting Cancel Subscription, and submitting the feedback form. The terms state that full refunds are available within 48 hours of purchase or renewal, dropping to a 50 percent refund up to 72 hours, with a transaction fee deduction of about 3.5 percent. However, the plans page lists a narrower 24-hour window for full refunds, and mobile purchases through Apple or Google do not qualify for direct web refunds.

Data rules also require attention. Knowt's terms set a minimum age of 13, and the Knowt privacy policy references COPPA parental consent for under-13s and FERPA in school settings. Students under 18 must have verifiable consent from a parent or legal guardian to access AI features. Students under 13 cannot purchase individual subscriptions.

Knowt Compared to Quizlet and Anki

Knowt includes Learn, Match, and test generation on user-created decks without charging a fee. If you are weighing other study platforms against Quizlet, read our breakdown of Quizlet alternatives to evaluate broader tool choices.

Who Should Pay for Knowt Ultra and Who Should Stay Free

If you study from cards you make yourself, you probably do not need Knowt Ultra. The free plan gives you unlimited manual cards, generous storage, and unrestricted use of the five study modes. If you already take organized notes and only need a digital deck for active recall, the free tier does the job.

Paying $24.99 a month or $149.99 a year is worth it only if you depend heavily on automated document processing. If you have dozens of dense PDF readings each month and want automated chapter outlines, or if you need an AI voice tutor to explain complex test prep materials, Ultra removes the bottleneck. Do not pay for Ultra just to study your own typed cards.

Our recommendation would change if Knowt placed the five core study modes behind a paywall, or if the free plan capped total flashcard deck creation. A lower Ultra price would also change it.

Before spending money on a subscription, test your study routine using the free tier on the Knowt website. Import one of your existing study sets, run through a complete session in Learn mode, and confirm whether the basic free tools meet your academic requirements.
