SoYouLearn – A flexible and advanced spaced repetition platform
Founder here. Note: This is spaced repetition. I bootstrapped this over the past 1 1&#x2F;2 years.<p>A few key differences:<p>- A central DB (it has over 1.8M flash cards) which anybody can edit. Card owner can accept&#x2F;reject the change request.<p>- Courses are just <i>references</i> to flash cards, nothing else.<p>- You decide what you want to learn &quot;Display me field X,Y,Z and prompt me to enter field &#x27;A&#x27;. You can choose any field&#x2F;audio)<p>- Efficiently add bulk audio to a course<p>- A super fast UI (it&#x27;s an SPA)<p>I have a few ideas for premium which (as far as I know) would bring features that don&#x27;t exist yet for any spaced repetition platform:<p>- Prioritized learning (learn the most pressing ones)<p>- In advance learning (You&#x27;ll be gone for the weekend, but it&#x27;s Friday and you have 1h time: You can prelearn &quot;long term&quot; flash cards that&#x27;d come around over the weekend).<p>Also for some tech background: Frontend is pure Clojurescript + Datascript. Backend is Clojure, Cassandra, Datomic, Elasticsearch. I&#x27;d use the tech stack again, hands down.<p>The best introduction is the video at the bottom of the landing page it show all the features. There are only few courses right now so early adopters should (hopefully) be willing to create their own courses.<p>Questions welcome.
