Study less. Remember more.
Dorothy is a spaced repetition tool that learns when you should study something and then delivers it to you in a daily quiz.
How it works
Efficiently memorize anything for the long-term
We predict, to the day, when you will forget the answer to a question.
We then quiz you on that question the day before, allowing you to get the most out of the time that you do spend studying and to help you keep every answer memorized.
Whether you’re learning a new language, preparing for a graduate school exam, or so much more, Dorothy will help you not forget a single thing.
Quiz focused
-
Return
When you learn something, open Dorothy and simply add a question. Then let go of any worries. We’ll let you know when it’s time to study.
-
Recall
Dorothy’s algorithms use spaced repetition to notify you at the optimal time to engage your brain in active recall. All you have to do is open it up and answer the question.
-
Reflect
A quick self-assessment updates your algorithms to improve efficiency and accuracy. You don’t have to think about anything else until it’s time for your next quiz.

I am absolutely blown away by the incredible impact that Dorothy has had on my ability to learn and retain information! This amazing memorization tool is nothing short of a game-changer... I personally use Dorothy to learn a new language, increase my vocabulary, and help me with trivia, and I cannot imagine going back to my old study methods now that I have discovered this amazing app.

I love Dorothy, and what I love the most about it is that when I wanted a spaced repetition tool, I just found your product, and onboarded here with so much ease and so much less friction. I didn't need to read the manuals to agree on a free plan and then do registration. It just started seamlessly.

I am an architect and I like to keep myself up to date. There are many areas that I want to continue studying and I would like to obtain some certifications. But I also try to have a balance between exercise, work, family, boyfriend, social life and my dog so Dorothy allows me to study and keep myself constantly in preparation to take the certifications exams, dedicating just a few minutes a day.

I really like that it’s not like a flash card app where there’s just a “practice” button and you can do as many cards as you want. I like that some days you have no questions, some days you have one, others you have 15. I’m cool with that and it’s a nice surprise what I’m gonna get each day. Also I’m sure this is scientifically better for learning than ad hoc “practice when you feel like it”.
