I’ve been looking for a fun way to create a personal curriculum, and this is perfect! I can write summaries of the things I’m reading and learning, and it turns it into a beautiful mind map! I also love the quiz feature!! It’s worth the upgrade! ### 5/5 — Incredible use of AI for deeper thinking and learning *2026-06-04* If you’re a person who acquires a lot of insights or experiences in a day and you want to remember that information, this app is phenomenal! The best part about it is that doesn’t just regurgitate the insights you provide it, but actually reframes them and rephrase them, adding deeper insights so that you actually retain the information more deeply and meaningfully. The quizzes are more like deeper reflections to me than strict memory checks. In short, it’s one of the most impressive and valuable uses for AI I’ve experienced to date. ### 1/5 — Hidden costs. *2026-05-21* This app forces you to sign up for “Premium” charges that will hit in 7 days without telling you what those charges could be. I’m not signing blank check for an app I’ve never even used. Deleted. **Developer response:** Hi, Thank you for your feedback. The app does not force a subscription, there is a free tier that we recently improved to be generous. I encourage you to give it a try. ## Frequently asked questions about Prismo ### What is Prismo's learning methodology?
