Two models
Knowunity's core is study notes published by students, whom it calls "Knowers". Knowunity claims more than 30 million users and a very large catalogue; its terms say content goes through an algorithmic check before publication. Finding a note on a curriculum chapter is often quick.
Mindlet doesn't start from another student's notes but from your own course: the one your teacher handed out, with its structure and examples. The AI turns it into cards, multiple-choice questions and open questions, and spaced repetition brings them back at the right time. Mindlet also has a Discover section with shared collections, but that's not where you start.
The AI
Knowie, Knowunity's AI, explains an exercise step by step, answers questions and generates flashcards, quizzes, study plans and practice exams. Knowunity says it works with several providers: OpenAI, Anthropic, Google and Mistral AI.
Mindlet's assistant knows your collections: it explains a notion another way, quizzes you, creates cards, and can talk to you out loud (in French only). Cards, document reading and voice run mainly on models from Mistral AI, a French company. Whatever the tool, AI can get things wrong: check what it produces.
Memory
On the Knowunity pages we checked, spaced repetition isn't named. Knowunity writes that Knowie spots topics you're stuck on and brings them back later, and it offers study plans. We couldn't verify more about how that scheduling works.
In Mindlet, every review is scheduled by FSRS-6, card by card, with settings adjusted weekly to how you forget. Each day you see what's due, you get at most one reminder a day, and your stats show what you're retaining. More on spaced repetition.
Price and ads
Knowunity is mostly free, with ads. Pro removes the ads, lifts the AI limits and adds exam grading; its French site listed it at €49.99 a year on 22 October 2026, next to a struck-through price that suggests a promotion. Weekly plans exist too. Its privacy policy mentions advertising tools (subject to consent) and says a transfer of data to the United States cannot be ruled out.
Mindlet shows no ads and sells no data. The free plan has no time limit; paid plans, from €5.99 a month on the web (€4.99 billed yearly), raise your generation capacity and cost a little more through the app stores. Purchases are for adults only. Details in your data and on pricing.
